Abstract excerpt
Serratia marcescens mutants, which excrete Escherichia coli alkaline phosphatase (APase) encoded by the plasmid-bearing phoA gene, were isolated after mutagenesis by N-methyl-N'-nitro-N-nitrosoguanidine. These mutants produced two to four times as much APase as did the parent strain under a phosphate-limiting condition, and more than 70% of the enzyme was released into the culture medium. In addition,...
