Enantioselective Alkylation of Hydrophobic Vitamin B12 Bearing a Binaphthyl Moiety [PDF]
, 1992 The enantioselective alkylation of hydrophobia vitamin B12 derivatives at the β-axial site was examined in methanol with various alkyl bromides, and those B12 analogues bearing a peripheral binaphthyl moiety showed the highest S-selectivity toward ...

Artificial Symbiosis for Bulk Production of Bacterial Cellulose Composites
Advanced Materials, EarlyView.Co‐cultivation of the cellulose‐producing bacterium with the microalga enables bulk formation of bacterial cellulose under static incubation, with photosynthetically active oxygen‐generating sites throughout the medium. This symbiotic platform supports 3D cellulosic constructs with geometries dictated by the vessel shape.

Principles for Rigorous Design and Application of Synthetic Microbial Communities
Advanced Science, EarlyView.SynComs are artificially designed to enable inter‐species metabolic interactions, metabolic division of labor, and ecological interactions that can elicit phenotypes like colonization stability and environmental adaptation. This systematic review explores the processes used to construct SynComs, the assessment of the mechanisms of metabolic interaction

Advanced Science, EarlyView.In the H‐type electrolytic cell, carbon dioxide is reduced to acetic acid via electro‐microbial catalysis. The simply processed acetic acid is further converted through biological fermentation into high‐value‐added products, including acrylic acid, L‐lactic acid, and β‐alanine.
