There is an increasing contradiction between humanity's growing demand for natural resources and relatively limited supplements. Thus, ecological security has received widespread attention, making it a research hotspot in the global environment important topic construction of civilization. Ebinur Lake Wetland typical arid wetland area considered as fragile sensitive ecosystem. Quantitative monitoring landscape patterns ecosystem great significance environmental protection. To clarify...

Abstract Qingke ( Hordeum vulgare L. var. nudum Hook. f.) is a cereal of Gramineae, and it an indispensable food crop for people in the Qinghai—Tibetan Plateau China. This work focused on dynamic changes volatile non‐volatile fractions qingke (Heilaoya), that is, black qingke, during steaming, flavor variations were discussed combined with their correlation. According to results sensory analysis, revealed rice sweet aroma increased extension steaming time reached maximum at 60 min, whereas...

Pseudomonas fluorescens (P. fluorescens) and fragi fragi), two kinds of psychrotrophic species with pathogenicity, are likely to contaminate foods cause diseases even in fairly cold environments, an outcome which should be suppressed. This paper investigates the antibacterial mechanisms Dellaglioa algida (D. algida), a new type low-temperature-resistant Lactobacillus, on such Pseudomonas. By enzyme treatment approach, substance existing cell-free supernatant (CFS) D. is preliminarily...

Microbiology Society journals contain high-quality research papers and topical review articles. We are a not-for-profit publisher we support invest in the microbiology community, to benefit of everyone. This supports our principal goal develop, expand strengthen networks available members so that they can generate new knowledge about microbes ensure it is shared with other communities.

Despite the importance of learning activities for older adults, proportion those engaging in such remains low. To devise interventions that would increase participation learning, it is essential to analyze psychosocial predictors learning. This study employed a cross-sectional design, with data collected through self-administrated questionnaire, and proposed two hypotheses: 1) Self-efficacy interest recognition effectiveness social support from family friends significantly predict will...

Fatty Acyl-ACP thioesterase (FAT) is a key enzyme controlling oil biosynthesis in plant seeds. FATs can be divided into two subfamilies, FATA and FATB according to their amino acid sequences substrate specificity. The Upland cotton genome contains 20 GhFAT genes, amongst which 6 genes were of the GhFATA subfamily 14 GhFATB subfamily. are unevenly distributed on chromosomes. have 5 or 7 exons exons. All proteins conserved Acyl-ACP_TE domain PLN02370 super family, typical characteristics...

Cotton is the main source of renewable fiber in world and primarily used for textile production. This study analyzed 3,487 papers on cotton research published during 1990 to 2021 from agronomy category Web Science (WoS). Papers were mainly written English (96.329%), 8,860 authors, 87 countries/territories, 1,661 organizations, 107 journals book series. The top five core Crop (433, 12.418%), Agronomy Journal (310, 8.89%), Weed Technology (205, 5.879%), Field Crops Research (203, 5.822%),...

Green onion (Allium fistulosum L.) is a popular spice for cuisine in East Asia its potent odor. The deep-frying process reduces the original pungency and imparts frying hedonistic flavor to boost consumption behavior. To investigate puzzle of variability, volatile non-volatile fractions deep-fried green oil (FO) were dynamically monitored using GC-O-MS & chemometrics. results showed that profile FO at 155℃ changed significantly. A total 144 odorants identified samples, which...

A pilot scale anaerobic sequencing batch reactor (ASBR, working volume 530 L), inoculated by sludge from an A2O process, was developed to investigate the start-up of ammonia oxidation (ANAMMOX) and its combination with denitrification for deep-level nitrogen removal saline wastewater. Simultaneously, flora structure analyzed. Results showed that under conditions temperature 35℃±1℃ reaction time 14 h, ANAMMOX successfully started-up after 160 days operation. During stabilized operation stage,...

A bare platinum (Pt) plate electrode, two composite Pt electrodes of Pt/polypyrrole/glassy carbon electrode (Pt/pPy/GCE) and nanoparticles/CeO 2 microspheres/GCE (Pt NPs/CeO /GCE) were prepared to investigate the electrochemical redox behaviors sulfur mustard (HD). Cyclic voltammetry (CV) measurements revealed irreversible oxidation peaks an reduction peak. All three had at 1.02 V (vs. saturated calomel (SCE)) 1.26 SCE), indicating formation bis(2-chloroethyl) sulfoxide sulfone on all...

Abstract This paper aimed to explore the effects of different varieties oils on volatile flavor compounds and fatty acid composition green onion deep-fried oils, establish fingerprints oils. The acids in 7 kinds were identified analyzed by electronic nose gas chromatography-mass spectrometry (GC-MS). results showed that sensory evaluations accepted detect odor differences sensitively. 103 components positively GC-MS, key aroma including aldehydes sulfur-containing correlated highly with...

Abstract Background Mexican Americans (MAs) are the fastest growing subpopulation in US. As this population ages, age‐related diseases such as Alzheimer’s disease (AD) will disproportionately affect MAs. MAs have a unique AD pathogenesis signature when compared to their non‐Hispanic White (NHW) counterparts. MtDNA damage may be implicated elevated burden among due high prevalence of common risk factors for cognitive impairment (CI) including metabolic comorbidities. Mitochondrial...

Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous at relatively high concentrations by atmospheric deposition, and they threatening to the environment. In this study, toxicity of naphthalene on tall fescue its potential responding mechanism was firstly studied integrating approaches. Tall seedlings were exposed 0, 20, 100 mg/L in a hydroponic environment for 9 days, toxic effects observed studies general physiological studies, chlorophyll fluorescence, root morphology. Additionally,...

Abstract Background and aims Intercropping of hyperaccumulators with commercial crops is widely accepted in single-metal-polluted farmland. However, the ecological risks non-hyperaccumulated metals intercropping systems have not been revealed. Methods To evaluate Pb Cu activation absorption an intercropped system Sedum alfredii Cicer arietinum L., sequential extraction dissolved organic matter (DOM) characterization were used to describe migration system.
