Isolation and identification of the dominant bacteria from the soil contaminated with hydrocarbon

The aim of this research to isolate and determine the most dominant bacteria in soil contaminated by hydrocarbons. Commercial, industrial, and military activity, largely in the 19th and 20th centuries, have led to environmental pollution that can threaten human health and ecosystem function are the major sources of energy for industry and daily life that cause environmental contamination during various stages of production, transportation, refining and use. Four samples of contaminated soil were collected from Al-Amriya Gas Filling Factory in November, 2023 sampling of depth (0-15 cm) then all samples transported to the laboratory. Results revealed that dominant isolates are Kocuria rosea, Escherichia coli, and Pseudomonas aeruginosa. These isolates identified depending on morphological cultural, gram stain, microscopic features, biochemical tests, and VITEK2 compact
