Method for producing xanthosine-5'-monophosphate by fermentation using mutant strains of Coryneform bacteria

摘要

Xanthosine-5'-monophosphate is produced by cultivating the bacterium which has a resistance to growth inhibition by an inhibitor selected from the group consisting of inhibitors of cell membrane biosynthesis and/or functioning, phosphorylation inhibitors, uncoupling agents, RNA-polymerase inhibitors and methionine analogs, and has an ability to produce xanthosine-5'-monophosphate according to produce and accumulate xanthosine-5'-monophosphate in the culture, and recovering the xanthosine-5'-monophosphate therefrom.
