Abstract
As a result of screening isoalkyl or isoalkenyl substituted aromatic hydrocarbon assimilating microorganisms, 19 strains of isopropylbenzene assimilating bacteria were isolated. Thirteen of these strains were found to grow on ct-methylstyrene and all 4 strains tested were also found to grow on isobutylbenzene.
Among them, 2 strains (S 107 Bl and S 182 Bl) were selected for further study and were identified as Ps. convexa and Ps. ovalis, respectively.
Furthermore, some examined aromatic hydrocarbon utilizing bacteria were classified into two groups by differences in substrate assimilation specificity.
