Abstract:
Human establishment on earth and the technical advancement followed by, has created water as t
resource in the world. Waste water has brought severe environmental and social impacts. Study is an

difficult to be degraded and removed via conventional treatment systems. The interest towards lipid
water treatment by microbial isolates has been rejuvenated due t o the high operational and mainte
associated with conventional treatment systems.
Study was attempted to isolate microorganisms capable of degrading lipids efficiently from diverse e
Hundred strains were screened and six strains were lipolytic
positive. Among the lipolytic positive strains, three strains (S1,S3 and S5) exhibited the cell growth
OD600=1 after 48 hours of cultivation. The optimum temperature was found to be 30 ºC for maximum
during 48 hours of culturing. Subsequently the lipid degradation competency of each strain was investig
30 ºC for about 24 hours where, the S1 yielded the highest lipid degradation efficiency (39.02±0.01% ).
S1 was accustomed for investigating the lipase activity (2.605±0.01) and the lipid degradation
(39.02±0.01%) against cell growth. S1, S3 and S5 were identified in accordance with morphologic
biochemical testing and 16S rRNA sequencing as Pseudomonas aeruginosa, Enterobacter cl

FOGs and environmental pollution occurred creating unpleasant odor.
Therefore, it is all-important to act on proper treatments to remove lipids from wastewater.
physicochemical waste water treatment methods that have been studied so far are sedimentation
degasification, screening, aeration, ozonation, coagulation, neutralization, chlorination, ion exchange an
Certain boundaries such as high cost, partial separation, occurrence of secondary pollutants and solid
large quantities and usage of chemicals associated with physicochemical strategies have emplaced
approaches as the promising candidates towards lipid contained waste water treatment.
