✦ Synopsis

Standing water from carbofuran-treated Azolla plots showing accelerated degradation was further enriched by ®ve repeated transfers to carbofuran-supplemented mineral salts medium. This enrichment culture developed from standing water of carbofuran-treated Azolla plot can utilise carbofuran as sole source of carbon and nitrogen. The enrichment culture was able to hydrolyse nearly 100% of [ring-14 C]carbofuran to carbofuran phenol in ®ve days, which accumulated in the medium, while the carbamate side-chain in [carbonyl-14 C]carbofuran was readily mineralized to [ 14 C]carbon dioxide. Enrichment culture was able to degrade carbofuran up to 1000 mg ml À1 levels in mineral salts medium with ease.
