Abstract:: ... Direct 3D bioprinting of bioreactors containing microorganisms embedded inside hydrogel structures is a promising strategy for biotechnological applications. Nevertheless, microporous hydrogel networks hinder the supply of nutrients and oxygen to the cell and limit cell migration and proliferation. To overcome this drawback, we developed a feedstock for 3D bioprinting structures with hierarchical ...

Using steady‐state and stopped‐flow kinetics, we show that the Escherichia coli nitroreductase NfsA is 20–50 fold more active with NADPH than with NADH and that product release may be rate‐limiting. The crystal structure of NfsA with NADP⁺ shows that a mobile loop form ...

Abstract:: ... Studies on trimethylamine (TMA) in egg yolk have focused on how it impacts the flavor of eggs, but there has been little focus on its other functions. We designed an in vitro antibacterial test of TMA according to TMA concentrations that covered the TMA contents typically found in egg yolk. The change in TMA content in yolk was analyzed at different storage temperatures and for different storage d ...
