Continuous anaerobic phenol degradation using an adapted mixed culture

Abstract

A mixed culture derived from cow dung and sewage sludge and adapted to phenol was used for anaerobic phenol degradation. The phenol degradation rate depended on the period of adaptation of the mixed culture to phenol. In the continuous process, a higher degradation rate (2500 mg.1(-1) d(-1)) and better reactor stability was achieved with a granular activated-carbon-packed bed reactor than with a stirred tank reactor.

Benzene bioremediation using cow dung microflora in two phase partitioning bioreactor

“…These macro-and microelements serve as a nutrient source for the growth and maintenance of microbial community. Bioremediation potential of cow dung microflora for benzene remediation has not been reported till date, only Satsangee and Ghosh [36] have reported the anaerobic phenol degradation using adapted mixed cultures derived from cow dung and sewage sludge and found a high degradation rate (2500 mg/l/d). Therefore, the present research study was carried out to evaluate the effectiveness of cow dung microflora for aerobic degradation of various concentrations of benzene.…”

Microbiological studies of effluents from the Nigerian fertilizer and paper recycling mill plants

“…The occurrence of these microbes in the effluents lead to excessive oxygen demand loading and also disturb the ecological equilibria of the receiving waters with much loss of aquatic life and intense pollution menance. It has therefore both health and economic consequencies [4]. Effluent discharge practicies in Nigeria are yet too crude and society is in danger, especially in the industrialised parts of the cities.…”
