Biodegradability of several guanyl compounds was estimated by the use of activated sludge under aerobic conditions and soil bacteria under anaerobic conditions and soil perfusion apparatus. Soil bacteria were isolated from the sediment in a sewage drainage. Activated sludge did not biodegradate guanidine, cyanoguanidine and guanylurea which were formed from calcium cyanamide fertilizer and known to be biodegrabated to ammonia in soil. Activated sludge biodegradated some guanyl compounds such as methylguanidine, hexamethylenediguanidine, creatine and creatinine. The change of nitrogen source from polypeptone to guanidine or cyanoguanidine affected the composition and population of microorganisms in activated sludge but it did not endow activated sludge with the biodegradating activity for guanidine and cyanoguanidine. Soil bacteria anaerobically degradated guanidine, cyanoguanidine and guanylurea which were not degradated by activated sludge. Soil bacteria under anaerobic conditions, however, did not degradate any of methyl derivatives of guanyl compounds-methylguanidine, which was degradated by activated sludge, 3-methylcyanoguanidine and 5-methylguanylurea-and hexamethylenediguanidine. By soil perfusion method, biodegradability of such eight guanyl compounds as guanidine, methyl-guanidine, hexamethylenediguanidine, 3-methylcyanoguanidine, guanylurea, 5-methylguanylurea, creatine and creatinine was estimated. Methylguanidine might be degradated to nitrate via another guanyl compound in soil. Neither guanylguanidine nor 1,1-dimethylguanylguanidine was degradated by any of estimation methods for biodegradation.
