Skrining Bakteri Hidrokarbonoklastik Dalampeningkatan Degradasi Minyak Bumi Dari Gas Bootpetapahan, Riau

Abstract

The research about Hydrocarbonoclaustic bacterial screening studies from the Gas boot area exploration Gathering Station (GS) of PT. Chevron Pacific Indonesia Petapahan Riau has done. The study aims to find hydrocarbonoclastic bacteria and test its ability to degrade petroleum. The research was carried out by the experimental method. The first step is isolating bacteria from the Gas boot. Isolation results obtained 4 bacterial isolates that were suspected as Hydrocarbonoclastic bacteria. The second stage is screening to prove the ability of these bacterial isolates to degrade petroleum. The screening method is done by growing bacterial isolates on 2% SMSS + petroleum media. The screening results showed 4 bacterial isolates were Hydrocarbonoclastic bacteria because it was known to be able to degrade petroleum hydrocarbons marked by a decrease in TPH and COD levels. The highest degradation rate of TPH and COD was shown by bacterial isolates IMB-03 with degradation rates of 39.23% TPH and 37.98% COD
