Abstract: | One species of hydrocarbon utilizing bacteria was isolated from soil. This strain was named as Achromobacter petrophilum No. 4017. This bacterial species utilizes normal hydrocarbons with carbon chains of nC10 to nC18, but does not utilize glucose or other carbohydrates. Achromobacter petrophilum forms small amounts of green-yellow, green-blue and violet fluorescent compounds in the medium containing n-hexadecane (nC16) as a carbon source. The mutant strain, No. 4510, which requires hypoxanthine and thiamine for growth, was obtained from Achromobacter petrophilum No. 4017 by ultraviolet irradiation and formed considerable amounts of green-yellow fluorescent compound by the addition of guanine to the n-hexadecane medium. This fluorescent compound was crystallized from culture broth. |
