and Summary Controlled amounts of C‐14 labeled trisodium car‐boxymethyloxysuccinate, an experimental detergent builder, were added to a laboratory anaerobic digester system. The daily dosages were increased incrementally from 4 to 20 ppm, dosages being held at each level for 24 days. Biodegradation commenced after 6 days, and once complete acclimation occurred, removals were rapid and complete at all dosage levels, yielding CO 2 and CH 4 as virtually the only end‐products of decomposition. After 96 days of application, total removal was in excess of 95%. Further, this com‐pound did not interfere with the normal digestion processes or display any inhibitory effects on the bacterial population.
