Abstract

Attemps were made to demonstrate the role of yeasts in the degradation of benzene compounds under natural soil conditions. Yeasts were isolated from acidic sandy soil supplied with benzene compounds. For this purpose the ‘slant culture method’ was used. Growth on the benzene compounds took place on solid growth media at 10°C. Several yeast species were isolated: Leucosporidium scottii, Rhodotorula aurantiaca, Rhodotorula mucilaginosa, Trichosporon dulcitum, Trichosporon moniliiforme and Schizoblastosporion starkeyi-henricii. Cryptococcus humicolus and Cryptococcus laurentii were isolated from liquid enrichment cultures. All these strains assimilated several benzene compounds in pure culture.

Cresol removal from contaminated soil was speeded up by inoculation with Rhodotorula aurantiaca G36. It was demonstrated that this yeast utilized this compound in competition with the soil microflora.
