Abstract excerpt
Approximately 470 strains of various microorganisms were tested for their ability to epoxidize cis-propenylphosphonate (PPOH) to (-)-cis-1,2-epoxypropylphosphonate (fosfomycin, FOM). Cellvibrio gilvus KY 3412 was selected as the best strain. To obtain higher activity, FOM-resistant strains were derived by N-methyl-N'-nitro-N-nitrosoguanidine mutagenesis. Mutant KY 3413, showing ten times higher FOM resistance,...
