Antibiotic inhibition of RNA catalysis: neomycin B binds to the catalytic core of the td group I intron displacing essential metal ions.
TLDR
How neomycin B binds to the intron RNA inhibiting splicing in vitro is reported, suggesting electrostatic interactions and competition with divalent metal ions. Expand
Production of glucose–fructose oxidoreductase and ethanol by Zymomonas mobilis ATCC 29191 in medium containing corn steep liquor as a source of vitamins
TLDR
It is confirmed that CSL is an effective and cheap supplement for Z. mobilis medium, increasing the economic potential of a large-scale bio-production of sorbitol and gluconic acid by untreated Zymomonas mobilis cells. Expand
