ABSTRACT

Isolation and optimization of Lipase producing bacteria from palm plantation soils of Michael Okpara University of Agriculture, Umudike was carried out using culture techniques. Microorganisms of four genera were isolated from the three samples collected from the areas under study. Bacillus, Staphylococcus and Pseudomonas occurred (100%) in all the samples which suggests them to be most prevalent while Enterobacteria sp occurred in only two samples (67%). Optimization was carried out using Pseudomonas  which showed highest clearance zone in the isolation medium. Maximal lipase production was achieved at the optimum incubation time of 48hours (25.90µ/mol), temperature of 40oC (24.41 µ/mol) and pH of 7.0 (24.59 µ/mol) using olive oil as the standard substrate. The effect of various substrate for optimum production of lipase was also investigated and palm oil was observed to have the peak enzyme activity. (22.07 µ/mol) That is to say that the search for novel gene for enzyme production should be channeled to soil sample exploitation.
