Bioremediation of phenol by a novel partitioning bioreactor using cow dung microbial consortia

Abstract

A bioreactor has been designed and developed for partitioning of aqueous and organic phases with a provision for aeration and stirring, a cooling system and a sampling port. The potential of a cow dung microbial consortium has been assessed for bioremediation of phenol in a single-phase bioreactor and a two-phase partitioning bioreactor. The advantages of the two-phase partitioning bioreactor are discussed. The Pseudomonas putida IFO 14671 has been isolated, cultured and identified from the cow dung microbial consortium as a high-potential phenol degrader. The methods developed in this study present an advance in bioremediation techniques for the biodegradation of organic compounds such as phenol using a bioreactor. We have also demonstrated the potential of microorganisms from cow dung as a source of biomass.

Benzene bioremediation using cow dung microflora in two phase partitioning bioreactor

“…In order to investigate some unique microbial source for bioremediation study, animal waste-cow dung has been used as a novel source. The presence of abundant macro and micronutrients provide suitable conditions for microbial growth in the cow dung, which could be an effective source for bioremediation of hazardous wastes [16,17].…”

Ethnoveterinary survey of tradomedical importance of <i>Bos taurus</i> L urine, bile and dung in Nigeria and South Africa

“…In a study, cow dung was found to be useful in bioremediation of pharmaceutical, pesticides and petrochemical waste [2,[29][30]. Interestingly in Nigeria, cow dung was assessed for aerobic, heterotrophic bacteria and petroleum-utilizing bacteria as well as degradation potential of petroleum-utilizing bacteria isolates [31].…”
