STUDIES ON MICROBIAL UTILIZATION OF D-GLUCURONIC ACID DERIVATIVES

I. POPULATION OF D-GLUCURONIC ACID-DECOMPOSING MICROORGANISMS AND ITS GROWTH PROMOTING EFFECT

Abstract

1) D-Glucuronic acid, D-glucuronolactone and ethyl D-glucuronate were decomposed by members of the colon-typhoid group of bacteria, Penicillium, Aspergillus and Streptomyces.
2) D-Glucuronamide could not be degraded by any organisms tested.
3) D-Glucuronic acid, D-glucuronolactone and ethyl D-glucuronate exhibited the growth-promoting effect on bacteria which could decompose them.
4) D-Glucuronamide also stimulated the growth of bacteria.
5) E. coli B-19 proved to decompose D-glucuronic acid, D-glucuronolactone and ethyl D-glucuronate adapitvely, but not n-glucuron amide.
