[Gel-producing properties of exopolysaccharide acrylamide in composition with agar-agar].

Abstract

A possibility to use a new polymer--exopolysaccharide acrylamide (EPAA)--for partial substitution of agar-agar in solid nutrient media in microbiology has been studied. It has been established than the EPAA in concentration 6.0-12.0 g/l with agar in concentration 10.0 g/l produce gel which is so strong as agar in concentration 15.0-20.0 g/l. Quality of gels produced depends an the method of EPAA mixing with agar. It has been shown that usage of EPAA in nutrient media does not affect growth, colony and cell morphology and biochemical properties of microorganisms. The use of EPAA to prepare nutrient media permits us to reduce expenditures for agar.
