Biosynthesis of the Biphenomycin Family of Potent Antibiotics

Angewandte Chemie International Edition, EarlyView.
The complete biosynthetic pathway of the biphenomycin antibiotics is elucidated, revealing a unique enzymatic machinery featuring a bifunctional MNIO, a regioselective arginase, a B12‐dependent rSAM for C,C coupling, hydroxylation enzymology, and a metalloprotease with dual‐specificity.

Efficacy of methylcobalamin to normalise elevated homocysteine of vitamin B12 deficient vegetarians: a double blind placebo control study [PDF]

, 2015
Vegetarians are known to be deficient in vitamin B12, due to a lack of dietary animal products, which can elevate plasma total homocysteine (tHcy). Elevated total tHcy can render vegetarians susceptible to cardiovascular disease (CVD).

Overview of Encapsulated Lysine and Methionine and Their Impacts on Transition Cow Performance and Health

Animal Research and One Health, EarlyView.
The transition period in dairy cows, spanning 3 weeks before and after calving, is a critical phase characterized by increased nutrient demands, reduced dry matter intake (DMI), and elevated risk of metabolic disorders such as negative nutrient balance (NNB), lipolysis, proteolysis, and oxidative stress.

Roles of Dietary Cobalt and Administration of Mixed Rumen Bacteria in Regulating Hematological Parameters of Pre-weaning Twin Lambs [PDF]

, 2013
Cobalt (Co) is required by rumen microorganism for vitamin B12 synthesis. Vitamin B12 is an important cofactor for methionine synthesis and gluconeogenesis.

Nanoparticle transport in epithelial cells: pathway switching through bioconjugation [PDF]

, 2013
The understanding and control of nanoparticle transport into and through cellular compartments is central to biomedical applications of nanotechnology. Here, it is shown that the transport pathway of 50 nm polystyrene nanoparticles decorated with vitamin

Effective pretreatment of wet microalgal biomass to enhance lipid extraction in biodiesel production

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Biodiesel is a viable alternative to fossil fuels. Identifying and evaluating nonedible sources is essential to address ecological concerns and meet energy demands. Microalgae are effective for lipid production but their rigid cell walls hinder bioproduct release making the process energy‐intensive and costly.

Adaptive Algal Cultivation Enabled by a Monthly Biomass Forecasting System

Biotechnology and Bioengineering, EarlyView.
The developed monthly algal forecasting system used to predict biomass production for two algal strains (A and B) at two pond water depths (low and high). The highest predicted production, achieved with strain A at a low pond water depth, is selected as the cultivation strategy to guide the next month's algal growth.

Impact of Cyanocobalamin and Methylcobalamin on Inflammatory Bowel Disease and the Intestinal Microbiota Composition.

Journal of Agricultural and Food Chemistry, 2018
Patients with inflammatory bowel disease (IBD) are usually advised to supplement various types of vitamin B12, because vitamin B12 is generally absorbed in the colon. Thus, in the current study, the influence of cyanocobalamin (CNCBL) or methylcobalamin (

Inherited metabolic epilepsies–established diseases, new approaches

Epilepsia Open, EarlyView.
Abstract Inherited metabolic epilepsies (IMEs) represent the inherited metabolic disorders (IMDs) in which epilepsy is a prevailing component, often determining other neurodevelopmental outcomes associated with the disorder. The different metabolic pathways affected by individual IMEs are the basis of their rarity and heterogeneity.
