Destruction of trimethylamine by strain Rhodococcus jialingiae HCT-91
Abstract
Strain Rhodococcus jialingiae HCT-91 isolated from natural sources is capable to utilize trimethylamine as a sole source of carbon and nitrogen. In batch culture it degrades toxicant in concentration 100 mg/l by 6 hours. Hypothetical pathway of trimethylamine catabolism by strain Rh. jialingiae HCT-91 was proposed. It was demonstrated that trimethylamine is oxidized to trimethylamine-N-oxide further split up to dimethylamine and acetaldehyde. Dimethylamine is degraded to methylamine and the latter is cleaved into acetaldehyde and ammonium. Acetaldehyde is broken down to carbon dioxide and water. As a result cells of strain Rh. jialingiae HCT-91 carry out complete trimethylamine mineralization.
