Nitrogen Availability Influences Biomass Composition in Yarrowia lipolytica Grown on Acetate

open access: yesFermentation
Microbial protein production from acetate represents a promising route for sustainable protein supply, yet its efficiency is constrained by limited understanding of carbon–nitrogen metabolic coordination.

A General Stereochemical Model for Grignard Additions to α‐Alkoxy Nitrones: Density Functional Theory Evidence for an Intrinsic α‐Chelation‐Controlled Pathway

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
A comprehensive DFT conformational study of Grignard additions to α‐alkoxy nitrones reveals that the reaction proceeds through a dinuclear α‐chelated transition structure in which the nitrone oxygen coordinates two magnesium centers. Other common additives, such as zinc dichloride, boron trifluoride, and dimethylaluminum chloride, were also studied ...

Aerobic denitrification in different dissolved oxygen conditions: nitrogen metabolism and electron distribution

open access: yesEnvironment International
Aerobic denitrification broadens the practical range of biological nitrogen removal processes in wastewater treatment. However, comprehensive examination of the impact of dissolved oxygen (DO) levels on the metabolic pathways of aerobic denitrifiers ...

Nitrogen fixation by a Bangladesh deepwater rice-field calothrix [PDF]

open access: yes, 1990
In order to study the influence on blue-green algal nitrogenase activity of environmental variables in deepwater rice-fields (DWR), a laboratory study was planned on a DWR isolate of Calothrix (D764).

Production of bioethanol from residual barley and utilization of fermentation co‐products in animal nutrition

open access: yesEnvironmental Progress &Sustainable Energy, EarlyView.
Abstract The search for sustainable alternatives for bioethanol production has encouraged the valorization of agro‐industrial residues. This study evaluated the use of residual barley as a feedstock for bioethanol production and as a potential ingredient for ruminant feed.

Stage‐Dependent Metabolic Reprogramming Drives a Self‐Organizing Microbial Network During Shanxi Aged Vinegar

open access: yesFood Bioengineering, EarlyView.
Metabolic shifts from growth to stress adaptation in Shanxi aged vinegar fermentation link flavor maturation and microbial cooperation, and Lactobacillus and Acetobacter form a self‐organizing metabolic network through division of labor. ABSTRACT Acetic acid fermentation (AAF) is a vital stage in the production of Shanxi aged vinegar (SAV), during ...

Neurolathyrism in Sub‐Saharan Africa—Assessing the Neurotoxic Risks of Lathyrus sativus Amid Drought and Food Security Challenges

open access: yesFood Safety and Health, EarlyView.
Representation of grass pea consumption in drought‐stricken sub‐Saharan Africa sustains nutrition, but excess β‐ODAP exposure due to multiple reasons triggers neurolathyrism, a progressive neurotoxic disorder. ABSTRACT Neurolathyrism is a progressive motor neuron disease due to the consumption of Lathyrus sativus (grass pea) over long periods.

Monitoring and Mitigation Strategies for Hazardous Compounds in Chinese Rice Wine (Huangjiu): A Comprehensive Review

open access: yesFood Safety and Health, EarlyView.
This review elucidates the formation pathways and detection technologies for ethyl carbamate, biogenic amines, and higher alcohols in Huangjiu. It concludes that integrated control frameworks are essential to decouple safety risks from the metabolic processes responsible for flavor development.

Late Pleistocene Volcanic Rocks From Tengchong Volcanic Field at SE Tibetan Plateau: Constraints on Petrogenesis and Mantle and Crustal Processes

open access: yesGeological Journal, EarlyView.
Early zircon saturation and crystallisation occur in mafic (52–54 wt.% SiO2) lavas at Tengchong volcanic field. These early formed zircons with high δ18O (6.6‰–7.9‰) indicates mantle enrichment by subducted supracrustal materials. ABSTRACT Late Pleistocene (< 0.2 Ma) mafic and evolved volcanic rocks occur in northern Tengchong Volcanic Field, SE ...
