Metabolism of carbamyl compounds by Streptomyces nitrificans

The Response of Poteriochromonas stipitata to Urethan and Related Compounds*

“…Thus, Lamanna PS Campbell (22) concluded that urethan behaved as a non-ionic surface active agent toward Saccharomyces cerevisiae. Studies with Streptomyces nitrificans ( 15,(17)(18)(19)(28)(29)(30) showed that the actinomycete could utilize urethan as sole source of energy, carbon and nitrogen, but did not offer a unifying explanation for the multifarious actions of urethan on living systems, We have surveyed the effects of ethyl carbamate on a number of protista. This report summarizes studies with a phagotrophic phytoflagellate, Poteriochromonas stipitata, which is suitably sensitive to the action of urethan.…”
