Abstract
|
|
|
|
A bacterium synthesizing extracellular polysaccharide was isolated from soil and identified as Enterobacter agglomerans. The polysaccharide was found to be glucan polymer containing glucose and galactose in a molar ratio of 1 : 1.1. The aqueous solution was very viscous. The viscosity of 1% solution was 264 mPa.s. at 42 sec^(-1) and yield stress was 4.89 Pa. The polysaccharide solution did not have thermal stability but pH and salt stability.
