New locus for exopolysaccharide overproduction in Escherichia coli K-12.
A new locus for exopolysaccharide overproduction in Escherichia coli K-12 was mapped by insertion mutagenesis. A 66% linkage to serA, which is located at 62 min on the E. coli K-12 linkage map, was shown by P1 transduction. The polysaccharide produced by the mutant was isolated and was shown to be similar to colanic acid.
