Streptococcus allantoicus and the Fermentation of Allantoin

Abstract

S. allantoicus, which is able to grow anaerobically with allantoin as a carbon and energy source, has been isolated from soil by the enrichment culture method. The fermentation of allantoin results in the formation of NH3, urea, CO2, and formic, acetic, lactic and oxamic acids, and possibly glycollic acid. The organism also carries out a modified homofermentative lactic acid fermentation of sugars.
