K Kegiatan eksploitasi minyak bumi (crude oil) berpotensi menimbulkan dampak negatif bagi lingkungan dan makhluk hidup. Crude oil sebagai limbah B3 (bahan berbahaya dan beracun) dapat menimbulkan pencemaran tanah, air tanah, dan/atau air. Tujuan studi literatur dalam bidang Bioteknologi Lingkungan ini untuk melakukan remediasi tanah tercemar minyak bumi secara enzimatis oleh bakteri Pseudomonas aeruginosa dan Brevibacterium casei pada kondisi lingkungan (pH dan temperatur) terkontrol. Studi diawali dengan melakukan analisis karakteristik bakteri indigenous yang diisolasi dari tanah tercemar minyak bumi dan kondisi lingkungan yang mendukung penyisihan Total Petroleum Hydrocarbon (TPH). Selain itu, juga dilakukan analisis perencanaan bioremediasi tumpahan minyak bumi pada skala pilot. Bakteri Brevibacterium casei dan Pseudomonas aeruginosa dikultivasi di dalam media pertumbuhan (growth media) Minimal Salts Media (MSM)yang mengandung mikro nutrient dan makro nutrient tanpa sumber karbon. Sampel tanah tercemar minyak bumi dilarutkan secara steril, kemudian dimasukkan ke dalam reaktor batch. Sampling dilakukan setiap hari hingga akhir penelitian. TPH diukur dengan Gas Chromatography (GC). Analisis Efisiensi penyisihan crude oil ditunjukkan oleh analisis persentase penurunan TPH selama penelitian berlangsung. Kedua jenis bakteri bekerja optimal pada temperatur optimum 30-35ºC dan pH optimum berkisar antara 7,0-8,0 untuk mendegradasi hidrokarbon pada sampel tanah tercemar sebanyak masing-masing lebih dari 69% dan lebih dari 76,2%. Dari hasil penelitian ini dapat disimpulkan bahwa kondisi lingkungan seperti temperatur dan pH memegang peranan penting bagi Brevibacterium casei dan Pseudomonas aeruginosa untuk mendegradasi hidrokarbon minyak bumi.

T The exploitation of crude oil has the potential to have a negative impact on the environment and living things. Crude oil as B3 waste (hazardous and toxic materials) can cause soil, ground water and/or water pollution. The purpose of this literature study in the field of environmental biotechnology is to enzymatically remediate petroleum contaminated soil by Pseudomonas aeruginosa and Brevibacterium casei bacteria under controlled environmental conditions (pH and temperature). The study begins by analyzing the characteristics of indigenous bacteria isolated from petroleum-contaminated soil and environmental conditions that support the removal of Total Petroleum Hydrocarbon (TPH). In addition, an analysis of petroleum spill bioremediation planning was also carried out on a pilot scale. Brevibacterium casei and Pseudomonas aeruginosa cultivated in the Minimal Salts Media (MSM) growth medium that containing micro-nutrients and macro nutrients without a carbon source. The crude oil-contaminated soil sample was dissolved in a sterile manner, then put into a reactor batch. Sampling was carried out every day until the end of the study. TPH was measured by Gas Chromatography (GC). Analysis of crude oil efficiency removal is shown by analysis of the percentage reduction in TPH during the study. Both types of bacteria worked optimally at the optimum temperature of 30-35ºC and the optimum pH ranged from 7.0-8.0 to degrade hydrocarbons in polluted soil samples of more than 69% and more than 76.2%, respectively. From the results of this study it can be concluded that environmental conditions such as temperature and pH play an important role for Brevibacterium casei and Pseudomonas aeruginosa to degrade petroleum hydrocarbons
