Abstract
The bacteriological profile of palm oil sale sites in selected markets in Kaduna state, Nigeria were evaluated using standard techniques by collecting a (60) soil samples. Aside from bacteriological profile, pH, moisture content, temperature and lipase activity analyzed. The soil samples had pH that ranged from acidic to neutral (3.0-8.00) which indicates the presence of hydrolytic enzymes. Microorganisms isolated from soil samples palm oil sale sites were screened from their lipase producing ability. A total of (10) ten bacteria belonging to the genera Bacillus, Streptococcus, Lactobacillus, Streptobacillus, Micrococcus, Staphylococcus and Pseudomonas. The lipolytic activity of the bacteria when screened on solid agar ranged for 1.1 to 3.2cm, 2.3-3.7cm, 2.3-6.7cm at 24, 48 and 72hours respectively while that of fungal species ranged from 0.6 to12cm, 0.3-1.5cm and 1.1-1. 7cm at 3,7,14 days of incubation respectively. Exo-enzyme was produced from the various species screened for lipolytic activities. The study shows that Bacillus subtilis and Trichoderma spp. had high potential.
