Notes:
Because branched-chain alkyl benzene sulfonate (ABS) is well known to create water pollution problems in surface water and ground water, a study was made on the biodegradation of this surfactant along with other anionic and nonionic surfactants in detergents by water bacteria. Biodegradation was evaluated by the conventional river die-away test employing the methylene-blue method or surface-tension techniques as analytical tools. Under anaerobic conditions, sugar detergents (sucrose esters) seem to be an ultimate solution to water problems created by branched-chain ABS; in aerated water, straight-chain ABS, sulfo tallow methyl esters, and nonionic surfactants are preferable to branched-chain ABS to improve water problems.
