Three hundred and ninety nine strains on the AN-7 medium and 146 strains on the AN-5 medium of hydrocarbon-utilizing microorganisms were isolated from 317 samples of cruide oil, oil brines, various types of soil etc. obtained in the Akita and Niigata oil fields and other places in Japan.Colonies of the microorganisms appeared in shorter days and the number of these colonies increased by adding a 0.1% yeast extract to basal medium for isolation.Among the samples obtained from the oil fields, oil-soaked soil was most effectual as an isola tion source while crude oil and oil brines were hardly efficient. Among ordinary soil samples, farm soil was more effective as compared with garden soil and river water etc.The number of isolates from the samples obtained in the Akita oil fields was larger than that from the Niigata oil fields and a positive regional difference was recognized between the two petroleum zones.
