Pseudomonas sp. strain C3211 was isolated from a temperate climate soil contaminated with creosote. This strain was able to degrade carbazole, dibenzothiophene and dibenzofuran at 10°C with acetone as a co‐substrate. When dibenzothiophene was degraded by strain C3211, an orange compound, which absorbed at 472 nm, accumulated in the medium. Degradation of dibenzofuran was followed by accumulation of a yellowish compound, absorbing at 462 nm. The temperature optimum of strain C3211 for degradation of dibenzothiophene and dibenzofuran was at 20 to 21°C, while the maximum temperature for degradation was at 27°C. Both compounds were degraded at 4°C. Degradation at 10°C was faster than degradation at 25°C. This indicates that strain C3211 is adapted to life at low temperatures.
