Comparison of Pyrene Biodegradation Using Two Types of Marine Bacterial Isolates

Polycyclic aromatic hydrocarbons (PAHs) contaminants have toxic, carcinogenic, and mutagenic properties. Screening bacteria from different sources capable of carrying out the biodegradation is essential for mapping mobilization purposes applying them to polluted hydrocarbon environments. The study aims compare capacity PAH by two types isolated sources. method applied interaction between bacterial suspension pyrene-contaminated waste 30 days. Biodegradation products in organic compounds were analyzed using gas chromatography/mass spectroscopy (GC/MS) Fourier transform infrared (FTIR). analysis results found several indications performance biodegradation: pyrene degradation Bacillus licheniformis strain ATCC 9789 (Bl) against was relatively more dominant than Sphingobacterium sp. 21 (Sb) bacteria. percentage total product type Sb (39.00%), that Bl (38.29%). test (Bl Sb) similar form alcohol carboxylic acid compounds. There no significant difference
