Abstract/Summary

Alkylbenzene sulfonate (ABS) is a primary chemical component of detergents and household cleaning aids. The foam that remains on the surface of water has become a major pollutant to our rivers and seas.;

The study dealt with the isolation of bacteria, from the sediments of Coastal Area, Manila Bay, and the degradation of ABS by these bacteria so that it becomes less harmful to the environment.

Fifteen strains of bacteria that have potential to degrade some concentration of alkylbenzene sulfonate have been isolated and characterized according to color, form, elevation, surface, density and margin. Most of the bacteria isolated have been identified as Gram negative with a few ascertained as Gram positive. Degradation rates computed from 14-42 days ranged from 0.0139-0.0700 mg ABS/day for a treatment supplemented with 2.5 mg ABS/L, 0.0246-0.0386 mg ABS/day for a treatment with 5.0 mg ABS/L, and 0.0071-0.0418 mg ABS/day for a treatment with 10.0 mg ABS/L.
