The soil provides habitat for a wide range of microorganisms such as bacteria to live. Their important roles in the ecosystem, some being beneficial while others could be pathogenic, demand certain study to understand their presence. This study was conducted aimed at isolating and identifying the bacterial species present in soil of a young oil palm plantation, and associate them to their role, either being pathogenic or beneficial in the ecosystem. Soil samples (0-15 cm) were collected randomly from a young oil palm area in UPM, Serdang, Selangor. Soil dilutions were made from 10 g of soil sample, and plated using drop plate technique on Nutrient Agar (NA) incorporated with cyclohexamide, and incubated at 25°C in darkness for 24 hours. Colony count was done followed by isolation process to obtain the pure culture. Isolates were identified by phenotypic fingerprint using BIOLOG Gen III Microplate ™. The isolated species were identified as Malikia spinosa, Bacillus humi, Bacillus cereus/thuringiensis, Bacillus pseudomycoides and Bacillus sp., with a total bacterial count of 3.9X10⁶ cfu/g of soil dry weight. The identified isolates are not pathogenic towards oil palm.
