Isolation And Identification Of Lipolytic Organisms In Palm Oil Contaminated Soil

ABSTRACT

The palm oil contaminated soil was evaluated for the presence of viable bacteria, fungi, and lipolytic microorgnnisms. The bacteria isolated included Staphylococcus sp, Micrococcus sp., Pseudomonas sp., Bacillus sp., and Corynebacterium sp. Fungi isolated included penicillium sp., aspergillus sp., and candida sp. The highest aei·obic count ranged fro 7.8 x 10cfu/g -4.4x 10cfu/g. paln oil sample G(POS G) has the least aerobic count of x4.4x 10°.palm oil sample I (POS I) has the highest coliform count of 3.9x 10cfu/g while palm oil sample G (POS G) has the least count of 2.3x 10cfu/g. highest fungi count · occurred in palm oil sample F(POS F) at 2.9x 10°cfu/g and least count in palm oil sample C (POS C) at I.Ox 106cfu/g. the highest and last lipoly5tic count occurred at palm oil sample J(POS J)2.8x 10° cfu/g and (l'OS I) 1.1 x 10 5 cfu/g respectively. Pseudomonas sp. And Staphylococcus sp have the highest number of isolates (10) and highl'st pcrccnt,1gc occurrence of 23.25% respectively. Aspergillus sp. and peuicilli11m sp. had the highest percentage occurrence of 34.-l8% respectively. The study has shown that the bacteria isolated arc potential lipase producers.
