A lambda lysogen with the prophage inserted into the arabinose B gene of Escherichia coli strain K-12 has been prepared. Induction of the phage from this lysogen yields viable phage at a frequency 4 X 10(-6) that found for induction of lysogens with phage inserted at the normal attachment site. Over 30% of the phage particles induced from the insertion in ara are arabinose-transducing phage. Th...

Abstract Oxidation of a mixture glucose and arabinose over Au particles deposited on porous carbons, N-doped carbons carbon nitrides was investigated at 70 °C, under constant pH 8, oxygen partial pressure 0.125 atm. In particular, nitrogen-containing carbon-based mesoporous structures demonstrated activity in the oxidation sugars to corresponding aldonic acids higher than gold undoped supports ...

Escherichia coli can rapidly switch to the metabolism of l-arabinose and d-xylose in the absence of its preferred carbon source, glucose, in a process called carbon catabolite repression. Transcription of the genes required for l-arabinose and d-xylose consumption is regulated by the sugar-responsive transcription factors, AraC and XylR. E. coli represents a promising candidate for biofuel prod...
