Abstract excerpt

Two mutants of Streptococcus gordonii which over-produced extracellular polysaccharide when grown on sucrose-containing medium were isolated after mutagenesis of strain Challis with ethyl methanesulphonate. The mutants, designated strains OB20 and OB30, expressed 2.6-fold and 4.7-fold respectivel...
