Machine learning to predict dynamic changes of pathogenic Vibrio spp. abundance on microplastics in marine environment.

Microplastics are widely found in the marine environment. Recent studies have shown that pathogenic microorganisms can hitchhike on microplastics, which might act as a vector for the spread of pathogens. Vibrio spp.

Synergistic effects of ultrasound and extraction solvent on the bioactive compound in kenaf seed oil.

Kenaf seed oil was extracted with 3 different solvents, i.e. hexane, ethanol and aqueous enzymatic medium with or without ultrasonic assistance.

Effect of Accelerated Storage on Fatty Acids, Thermal Properties and Bioactive Compounds of Kenaf Seed Oil.

The effects of thermal oxidation at 65 °C for 24 days on oxidation indices, fatty acid positional distribution, thermal properties, vitamin E composition and sterol composition of kenaf seed oil are investigated. The results showed that total oxidation value (TOTOX) of the oil increased from initial 8.83 to 130.

Leaching of indium from end-of-life LCD panels via catalysis by synergistic microbial communities.

Currently, a large amount of discarded liquid crystal displays (LCDs) are being produced, and the improper treatment of discarded LCDs causes serious environmental pollution problems. Indium is the most valuable metal in LCDs and is present in such devices at a concentration of over 0.025%.

Changes to the tropomyosin structure alter the angiotensin-converting enzyme inhibitory activity and texture profiles of eel balls under high hydrostatic pressure.

Changes in the structure of tropomyosin (TM) altered the texture profiles of eel balls and the inhibitory activity of the angiotensin-converting enzyme (ACE). The secondary and tertiary structure of TM was determined after high hydrostatic pressure (HHP) treatment. The correlation between the spatial structure of TM and the texture profiles of eel balls was developed and discussed.

Insights into the role of nanoalloy surface compositions toward catalytic acetone hydrogenation.

A significant composition-dependent catalysis behavior was observed in catalytic acetone hydrogenation. Carbon supported PtRu alloy nanoparticles (NPs) with optimal surface composition achieved ultra-efficient and highly selective production of isopropyl alcohol.

Effects of gamma irradiation on aflatoxin B levels in soybean and on the properties of soybean and soybean oil.

Fungal infection is inevitable in the cultivation and storage process of soybean. Gamma irradiation is an effective method to control fungal growth and inactivate mycotoxins. The effects of gamma irradiation and fungal damage on the number of fungi, aflatoxin B content, proximate composition of soybeans, and quality of soybean oil (acid value, peroxide value, iodine value, fatty acid profile, tocopherols content, and oxidation stability) were investigated in this work.

Optimization of Supercritical Carbon Dioxide Extraction of Eucommia ulmoides Seed Oil and Quality Evaluation of the Oil.

Supercritical carbon dioxide extraction (SC-CO) technology was used to extract oil from Eucommia ulmoides seed. The optimum conditions and significant parameters in SC-CO were obtained using response surface methodology (RSM). The qualities of the extracted oil were evaluated by physicochemical properties, fatty acid composition, vitamin E composition.

Determination of ultra-low milk fat content using dual-wavelength ultraviolet spectroscopy.

A precise determination of milk fat content in dairy products is of great practical importance. Several studies have reported methods to determine the milk fat content in commercial dairy products. However, very few of them validated or tested cases where the fat milk fat content was ultra-low.

Design, synthesis, and biological activity of oxime ether strobilurin derivatives containing indole moiety as novel fungicide.

Twenty-one novel oxime ether strobilurins containing indole moiety, which employed an indole group to stabilize the E-styryl group in Enoxastrobin, were designed and synthesized. The biological assay indicated that most compounds exhibited potent fungicidal activities. The structure-activity relationship study demonstrated that the synthesized methyl 3-methoxypropenoate oxime ethers 7b-e exhibited remarkably high activities among all the synthesized oxime ether compounds 7.

Antiretrogradation in cooked starch-based product application of tea polyphenols.

Unlabelled: Retrogradation in cooked starch-based products is a significant hindrance in extending the shelf life of these products as they become progressively hard to bite over short time periods (say 1 or 2 months). In this study, the effects of tea polyphenols (TPs) on cooked amylopectin-rich cassava starch have been investigated. Cassava starch was mixed with TPs and then gelatinized to form starch gels.

Design, synthesis and structure-activity relationship of novel oxime ether strobilurin derivatives containing substituted benzofurans.

Background: Strobilurins are one of the most important classes of agricultural fungicides. To discover new strobilurin analogues with broad spectrum and high activity, a series of novel oxime ether strobilurin derivatives containing substituted benzofurans in the side chain were synthesised and bioassayed.

Results: The synthesised compounds were characterised by (1) H NMR, (13) C NMR, MS and HRMS.

Synthesis and fungicidal activities of novel benzothiophene-substituted oxime ether strobilurins.

Twenty-one novel benzothiophene-substituted oxime ether strobilurins, which employed a benzothiophene group to stabilise the E-styryl group in Enoxastrobin (an unsaturated oxime strobilurin fungicide developed by Shenyang Research Institute of Chemical Industry, China) were designed and synthesised. The biological assay indicated that most compounds exhibited good or excellent fungicidal activities, especially against Colletotrichum lagenarium and Puccinia sorghi Schw. In addition, methyl 3-methoxypropenoate oxime ethers and N-methoxy-carbamic acid methyl esters exhibited good in vivo fungicidal activities against Erysiphe graminis, Colletotrichum lagenarium and Puccinia sorghi Schw.
