Short Communication: Determination of crude oil degradation efficiency of biofilm producing bacteria isolated from oil contaminated site

Abstract. Khoo DH, Shivanand P, Taha H. 2022. Short Communication: Determination of crude oil degradation efficiency biofilm producing bacteria isolated from contaminated site. Biodiversitas 23: 4138-4143. Microbes have gained much attention for their application in the bioremediation petroleum areas, and are considered potential candidates this purpose. The aim study was to screen six degrading bacterial strains ability form biofilm, measure selected strains. It found that only two strains, Micrococcus sp. UBDBH15 Pseudomonas UBDBH26 were categorized as strong producers, with latter showing highest amount formed. Under conditions tested, also rate (0.0047 g/day) a significant 7.07 ± 3.02 11.38 2.93 % after 7 14 days respectively. had lower (0.0033 g/day), resulting non-significant degradation. However, comparison non-biofilm producer, Enterobacter UBDBH06, suggested might enhance oil, but further studies needed confirm assumption.
