Abstract.

Rhodococcus erythropolis strain UPV-1 is able to grow on phenol as the only carbon and energy source and to remove formaldehyde completely from both synthetic and industrial wastewater. The rate of formaldehyde removal is independent of either initial biomass or formaldehyde concentration. The presence of viable, intact cells is strictly necessary for this removal to take place. Discontinuous and continuous formaldehyde-feed systems were successfully tested with synthetic wastewater in shaken flasks. Once biodegradation was well established in model synthetic wastewater, a real wastewater sample was obtained from a local phenolic and melamine resin-manufacturing company. Incubation of biomass with this wastewater at subtoxic concentrations of formaldehyde resulted in the complete removal of the pollutant. Parameters, such as chemical oxygen demand and toxicity, were assessed as indicators of wastewater cleanup progress.
