Abstract : Aromatic compounds are the most widespread class of organic compounds in the environment after carbohydrates, and these compounds belong to one of the most accumulated toxic pollutants in the environment. Aromatic compounds exist naturally in the environment not only but also are spread widely resulting from anthropogenic activities. The most significant aromatic compounds is oil and its derivatives; one of the biggest producers of petroleum in the world is Saudi Arabia. Biodegradation is a safe and effective method of biological treatment using different types of aromatic compounds are the most prevalent kind of organic compounds in the environment after carbohydrates, and these compounds belong to one of the most accumulated toxic pollutants in the environment. Samples were isolated from the Red Sea in Western industrial sites in Saudi Arabia. Three bacterial strains were identified using 16S-rRNA gene sequencing (Microbacterium esteraromaticum, Arthrobacter sp. PGP41, and Enterobacter hormaechei). A spectrophotometer at wavelength 600 nm was used to measure the degradation growth rate of these strains with different aromatic compounds (benzene, toluene, xylene, and phenol) as a carbon source. Microbacterium esteraromaticum and Enterobacter hormaechei reached the maximum growth consumption of xylene as a carbon source for 10 days. While Arthrobacter sp. PGP41 reached the maximum growth consumption of toluene for 10 days. By HPLC analysis to measure degradation rate, the Microbacterium esteraromaticum was high degraded by around 22.2% of xylene at 10 days. While Arthrobacter sp. PGP41 was highly degraded with toluene for 10 days. Benzene was efficiently degraded by approximately 23% with Enterobacter hormaechei strain R1 in 96 hours.
