Exogenous plant growth regulators/plant growth promoting bacteria roles in mitigating water-deficit stress on chicory (Cichorium pumilum Jacq.) at a physiological level

Plants respond differently to water-deficit stress conditions in the soil. In order to study different irrigation regimes and plant growth regulators/plant growth promoting bacteria effects on some physiological characteristics and inulin content in chicory plants, experiments were conducted as a factorial based on randomized complete block design with five replications at the greenhouse of Agricultural Faculty of Azarbaijan Shahid Madani University, Tabriz, Iran in 2017-2018. Experimental factors were different irrigation regimes: ((i) irrigation at the 55 %; (ii) irrigation at the 30 %; and (iii) irrigation at the 10 % of total available water capacity in the soil) and plant growth regulators including methyl jasmonate, uniconazole, chlormequat chloride and the solution containing plant growth promoting bacteria. Results indicated that the lowest relative water content, membrane stability index, chlorophyll a, b, total chlorophyll, carotenoids; soluble sugars and inulin in the roots; and the highest thiobarbituric acid reactive substances, proline, and soluble sugars in the leaves were related to severe water-deficit stress in the soil. Relative water content, membrane stability index, chlorophyll a, b, total chlorophyll, carotenoids, proline (except of plant growth promoting bacteria), soluble sugars and inulin increased, whereas thiobarbituric acid reactive substances decreased by the application of exogenous plant growth regulators/plant growth promoting bacteria compared with control plants. Interaction effects revealed that plant growth regulators/plant growth promoting bacteria could diminish water-deficit stress adverse effects in chicory plants at a physiological level by regulating endogenous phytohormones and antioxidant enzymes. In general, exogenous plant growth regulators especially uniconazole and plant growth promoting bacteria, improved inulin content in chicory plants compared with control plants.

Cetylpyridinium picrate: Spectroscopy, conductivity and DFT investigation of the structure of a new ionic liquid

A new cetylpyridinium picrate ionic liquid has been synthesized and characterized by differential thermal analysis, XRD, FT-IR, and NMR (H-1 and C-13) spectroscopy. Differential thermal analysis indicates the congruent melting of cetylpyridinium picrate and a temperature range of liquid state is 47-267 degrees C. A solid form of the sample characterized with a polymorphic transformation at 37 degrees C, which was confirmed via the XRD analysis. The interionic charge-transfer interactions, namely the charge transfer from the picrate anion to the cetylpyridinium cation, were detected by comparison of NMR spectra of DMSO solutions of the ionic liquid and cetylpyridinium chloride. The H-NMR chemical shifts’ differences of about 0.2 ppm and 0.1 ppm were observed in the case of the o-protons and the oz-methylene group protons, respectively. Additionally, the charge-transfering between the attracted ions was confirmed by DFT calculations. Based on the solid state NMR technique, the higher ions mobility was suggested for the solid sample of the ionic liquid in comparison to the solid cetylpyridinium chloride monohydrate. Moreover, the association constants K-A at 22, 30, 40, and 50 degrees C, obtained from the electrical conductivity measurements, clearly testifies much lower dissociation in the case of picrate. The K-A values of cetylpyridinium picrate and chloride in DMSO medium at 22 degrees C equal 748.7 L/mol and 525.0 L/mol, respectively. The performed DFT computations of the reduced density gradient function in four proposed structures of the new ionic liquid cation-anion pair identifies the presence of weak non-covalent C-H center dot center dot center dot O=N interactions between cetyl chain hydrogen atoms and nitro groups of picrate was explored through DFT calculations and analysis of the RDG function.

A simple cation exchange model to assess the competitive adsorption between the herbicide paraquat and the biocide benzalkonium chloride on montmorillonite

Since adsorption on clay minerals is one of the most popular water-pollutant removal method, it is important to consider the coexistence of several compounds that can affect pollutant retention. In this work, the competitive behaviour between cationic herbicide paraquat (PQ) and a benzalkonium chloride compound (BAC) on montmorillonite (MMT) was performed by adsorption experiments and analysed by a theoretical cation exchange model. Experimental studies included adsorption isotherms, XRD, FTIR and zeta potential (zeta). Binary systems (BAC + PQ) were performed at different initial concentrations ratio BAC/PQ = 0.1; 0.5; 1.0; 2.0 and 3.0. Results showed that at higher BAC initial concentration, the maximum adsorbed PQ amount decreases. X-Ray diffractograms showed that as the BAC/PQ ratio increases, the MMT basal spacing peak shifts to lower angles suggesting that the basal spacing is mainly controlled by the presence of BAC. Besides, the total adsorbed amount (adsorbed PQ plus adsorbed BAC) is closer to clay CEC value (0.91 mEq g(-1)), at this value zeta similar or equal to 0 mV suggesting that the adsorption occurs through a cation exchange mechanism. The theoretical model applied was originally developed to describe the exchange of simple cations on clay minerals, however it was effective in predicting the behaviour of larger cations such as PQ and BAC. In this scenario, thermodynamic parameters calculated through the model indicate that cation exchange process is spontaneous towards adsorbed BAC, suggesting that an adsorbed PQ cation is replaced by an equivalent amount of BAC cation (expressed in terms of electrical charge).

Aerobic and Anaerobic Biodegradability of Organophosphates in Activated Sludge Derived From Kitchen Garbage Biomass and Agricultural Residues

Organophosphates (also known as organophosphate esters, OPEs) have in recent years been found to be significant pollutants in both aerobic and anaerobic activated sludge. Food waste, such as kitchen garbage and agricultural residues, can be used as co-substrates to treat the active sludge in sewage treatment plants (STPs). We investigated the biodegradability of nine OPEs derived from kitchen garbage biomass and agricultural residues under different conditions. Under anaerobic conditions, the rate of removal of triphenyl ester OPEs was significantly higher than that of chloride and alkyl OPEs. The addition of FeCl3 and Fe powder increased the rate of degradation of triphenyl ester OPEs, with a DT50 for triphenyl ester OPEs of 1.7-3.8 d for FeCl3 and 1.3-4.7 d for Fe powder, compared to a DT50 of 4.3-6.9 d for the blank control. Addition of an electron donor and a rhamnolipid increased the rate of removal of chlorinated OPEs, with DT50 values for tris(2-carboxyethyl)phosphine) (TCEP) and tris(1,3-dichloroisopropyl)phosphate (TDCPP) of 18.4 and 10.0 d, respectively, following addition of the electron donor, and 13.7 and 3.0 d, respectively, following addition of the rhamnolipid. However, addition of an electron donor, electron acceptor, surfactant, and Fe powder did not always increase the degradation of different kinds of OPEs, which was closely related to the structure of the OPEs. No treatment increased the removal of alkyl OPEs due to their low anaerobic degradability. Tween 80, a non-ionic surfactant, inhibited anaerobic degradation to some degree for all OPEs. Under aerobic conditions, alkyl OPEs were more easily degraded, chlorinated OPEs needed a long adaptation period to degrade and finally attain a 90% removal rate, while the rates of degradation of triphenyl ester OPEs were significantly affected by the concentration of sludge. Higher sludge concentrations help microorganisms to adapt and remove OPEs. This study provides new insights into methods for eliminating emerging pollutants using activated sludge cultured with kitchen garbage biomass and agricultural residues.

Hepato-renal toxicities associated with heavy metal contamination of water sources among residents of an oil contaminated area in Nigeria

Objectives: This study was conducted to estimate the heavy metal (HM) content of water sources from oil contaminated area, HM and hepato-renal functions of residents and to determine association between consumption of crude oil contaminated water and development of multiple organ toxicities. Methods: Heavy metals (Pb, Cd, As, Hg) content of 20 surface water sources (SWS) and 20 underground water sources (UWS) from crude oil contaminated area and 40 water sources (20 SWS and 20 UWS) from uncontaminated area (controls) were estimated using AAS. The HM, indices of liver function (aspartate and alanine aminotransferases (AST and ALT), alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT), total protein (TP), albumin, total and conjugated bilirubin (TB and CB)) and renal functions (urea, creatinine, sodium, chloride, potassium, bicarbonate and kidney injury molecule-1 (KIM-1)) were determined in 120 residents each from contaminated and control areas using enzyme-colorimetry and ELISA methods. Results: The HM levels of all water sources studied were above WHO standards. Water sources from contaminated area had higher HM levels compared to control. HM contents of SWS from contaminated area and control were higher than UWS from both areas. Residents of contaminated area had higher levels of HM, urea, bicarbonate, chloride, sodium, KIM-1, ALP, GGT, AST, ALT, TB and CB and lower TP and albumin compared to residents of control area. Conclusion: Water contamination with crude oil is associated with elevated HM content with perturbations in HM, liver and renal functions of consumers which may suggest an increased risk of hepato-renal toxicities.

The Concrete Performance with Iron Tailings Sand Modified by Polypropylene Fibers under Aggressive Environment

This paper aimed to explore the performance of concrete with iron tailings sand modified by polypropylene fibers under aggressive environment. Three kinds of concrete (ordinary concrete, concrete with iron tailings sand (ITS), and concrete with ITS modified by polypropylene fibers) were exposed to drying-wetting cycles in 5% Na2SO4 solution for 28, 56, 84, 112, and 140 days. The performance, such as pores distribution, crack width, corrosion products, mass variation, expansion variation, compressive strength, flexural strength, and the diffusion of sulfate ion were measured at regular time intervals during the whole exposure period to describe the associated evolution laws. The results show that, in the process of the corrosion of sodium sulfate solution, the formation of gypsum and ettringite (AFT) has an important impact on the harmful pores (>0.1 mu m), cracks, mass variation, expansion variation, compressive strength, and flexural strength of the three concrete. Polypropylene fibers can refine the pores development and inhabit the crack development of the concrete with ITS, further alleviating the rate of sulfate ion attack on concrete and the rate of increase of corrosion products, so that the mass variation, the expansion variation, and the reduction of compressive strength and flexural strength can be limited effectively. Furthermore, in the concrete with ITS modified by 0.1% polypropylene fibers, the content of sulfate ions diffused is always the lowest.

Durability deterioration of concrete under marine environment from material to structure: A critical review

Durability deterioration of cementitious concrete and reinforced concrete (RC) is critical to durability, safety, and sustainability of infrastructures, especially for offshore concrete structures under marine environment. In this paper, the effects of marine environment on the deterioration mechanism, performance, and durability of concrete materials and structures are systematically reviewed. For the deterioration mechanism, the effect of various chemicals in seawater and different marine exposure zones on the cementitious concrete and reinforced concrete is firstly analyzed and compared. At material level, this paper discusses the characterizations of cementitious concrete, including compressive strength, chloride diffusion, carbonation depth, and pore structure. On the other hand, the performance of cementitious concrete with the addition of supplementary cementitious materials was also compared when exposed to marine environment. At structure level, the durability of RC structures, including beams and slabs and other elements with corrosion protection under marine environment is evaluated. This paper also assesses some cases studies of RC structures after many years of exposure to marine environment. Furthermore, prospectives are proposed for practical applications on concrete under marine environment. The conclusions are of great benefit to the researchers and engineers in the concrete-related industry who aim to develop durable and sustainable concrete infrastructures under marine environment.

Profiling the occurrence of biogenic amines in different types of tuna samples using an improved analytical approach

Food deterioration caused by microbial agents often involve the formation of biogenic amines (BAs), which can have harmful effects on human health. In this study a set of BAs – tryptamine, cadaverine, putrescine, spermine, histamine, tyramine, and spermidine, were simultaneously analysed to monitor their occurrence in different types of tuna samples. An improved extraction approach involving ultrasound-assisted microextraction (USA mu ET) followed by derivatization with dansyl chloride (DnsCl) and analysis by ultrahigh performance liquid chromatography (UHPLC) with fluorescence detection was validated for BAs quantification. The performance of the USA mu ET/UHPLC-FLD was assessed by studying the limits of detection (LOD) and quantification (LOQ), linear dynamic range (LDR), precision (intra and inter-day) and matrix effect (ME). Good linearity (r(2) > 0.98), LODs (from 0.98 to 8.57 mg kg(-1)) and LOQs (3.20-25.6 mg kg(-1)) were achieved for all BAs analysed. Recoveries ranged from 76% to 106%, with relative standard deviations (RSD) lower than 5.0%. ME was determined from 7.52 to 50% and the intra and inter-day precisions ranged from 4.7 to 11.6% and 5.5-14.2%, respectively. BAs levels varied significantly from 4.09 +/- 0.8 mg kg(-1) of putrescine in olive oil canned samples to 577.9 +/- 5.9 mg kg(-1) of cadaverine in natural canned samples. Tryptamine and tyramine were not detected in any of the samples analysed, while spermine and spermidine were found in 85.7% of the assayed tuna samples. Cadaverine was the most dominant BA with concentrations ranging from 54.3 +/- 2.5 mg kg(-1), in olive oil canned tuna, to 577.9 +/- 5.9 mg kg(-1), in natural canned samples, whereas putrescine had the lowest concentration (average 6.9 +/- 2.5 mg kg(-1)). The validated methodology revealed important improvements in terms of simplification of the experimental layout, expressed in the low sample and reagent amounts, in addition to less time-consuming and labour-intensive requirements that did not compromise the analytical performance.

Corrosion Inhibition Effect of Microorganism on 5754 Al Alloy in Seawater

Currently, with the gradual depletion of onshore resources, more efforts are being devoted to both scientific and resource exploitation of the ocean and the deep sea. Compared with the onshore environment, marine habitats are complex and characterized by high hydrostatic pressure, high salinity, and high marine population. The ocean is a unique aquatic environment, and it has a large population of microorganisms. There is a need to exploit the ocean for new energy sources. The significant challenges of exploiting oil, gas, and minerals have forced the people to innovate and develop advanced exploration tools. Al alloys are attractive for use in marine environments due to their low densities, high strengths, good plasticity, excellent electrical and thermal conductivities, and excellent corrosion resistance. The high chloride concentrations and microorganisms in the ocean have a significant effect on the corrosion resistance of many metallic materials. In this work, the corrosion behavior of 5754 Al alloy in seawater containing B.subtilis was investigated. The corrosion rate was analyzed by the weight loss method. The morphologies of the corrosion products and the corrosion profiles were observed by SEM and white light interferometer, respectively. The corrosion products were analyzed by energy dispersive spectroscopy and XRD. Finally, the corrosion mechanism of the Al alloy was studied using electrochemical impedance spectroscopy. The results show that the corrosion rate of the Al alloy in the seawater with B.subtilis was 12.5 mg/(dm(2).d), which was only 1/6 times that in the seawater without the bacteria. A protective film comprising of CaMg(CO3)(2), was gradually formed on the surface of the alloy in the presence of the bacteria. The bacteria promoted the formation of the CaMg(CO3)(2 )film, which protected the alloy from the seawater, and consequently, inhibited the pitting corrosion of the Al alloy in the marine environment.

Iron oxide nanoparticle synthesis using trigonella and tomato extracts and their antibacterial activity

Iron oxide nanoparticles (IONPs) were synthesised by combining the extracts of new plants (trigonella and tomato) with ferric chloride salt (FeCl3) via a simple chemical method at 200 degrees C for 2 hours. The biomolecules in the extracts play an important part in transforming FeCl3 to FeO NPs, which demonstrate antibacterial properties. IONPs were characterised via X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), and Fourier-transform infrared spectroscopy (FT-IR). XRD revealed a crystallite size of 17 nm with a body centre cubic (BCC) structure (wustite) phase for FeO NPs made using trigonella extract. FeO NPs synthesised using tomato extract were 41 nm, and the diffraction peaks revealed a BCC structure phase with excellent crystal quality. FE-SEM images demonstrated that the average grain size of Fe2O3 without using any plant extract was approximately 31.36 to 125.5 nm, while for the FeO NPs using tomato extract, it was approximately 48.18 to 77.54 nm, and for trigonella extract, 27.91 to 40.94 nm. In the FT-IR spectra of IONPs with and without plant extract, a strong peak appeared at 699 cm(-1) for FeO NPs using trigonella extract and 655 cm(-1) using tomato extract. Antibacterial activity of IONPs was determined by growth inhibition zones of the gram-negative bacteria Klebsiellapneumonia and gram-positive bacteria Staphylococcus aureus. The growth inhibition zones for FeO NPs using trigonella extract were 42 and 47 mm, respectively. The zones for FeO NPs using tomato extract were smaller (30 mm and 35 mm, respectively). These NPs may be effective in healing infections caused by these bacteria.
