| Abstract: | Studies on bioremediation of high fat and
oil wastewater by selected lipase producing bacteria like Bacillus subtilis, B licheniformis, B amyloliquefaciens, Serratia marsescens, Pseudomonas
aeruginosa and Staphylococcus aureus were carried out in wastewaters
emanating from palm oil mill, dairy, slaughter house, soap industry and
domestic wastewater with both individual and mixed culture (consortia). BOD and
lipase degradation was analyzed for 12 d. After 12 d of bioremediation, least
BOD and lipid content was observed in consortia. Among the six isolates, P.
aeruginosa showed least BOD (112
mg/L) in palm oil effluent, (82 mg/L) dairy effluent, (145 mg/L) soap
and (9 mg/L) domestic water effluent, whereas S. aureus showed least BOD (11 mg/L) in slaughter
house wastewater. Lipid content was
also reduced most by consortia after 12 d of bioremediation. P. aeruginosa
resulted in very good lipid degradation in palm oil effluent (325 mg/L),
soap effluent (300 mg/L) and domestic wastewater (17 mg/L), whereas S. marsescens showed good lipid
degradation in dairy effluents (280 mg/L) and S. aureus in slaughter house wastewater (320 mg/L). |
