Abstrakt: Bacillussp. strain JF8, which was isolated from compost, utilizes naphthalene and biphenyl as carbon sources at 60°C. Biphenyl grown cells of strain JF8 barely degraded naphthalene while naphthalene grown cells did not degrade p‐chlorobiphenyl, suggesting the existence of two independent degradation pathways. Isolation of JF8N, a mutant strain which can not utilize biphenyl as a carbon source while retaining the ability to utilize naphthalene, supports this hypothesis. Biphenyl grown cells of strain JF8 can degrade several polychlorinated biphenyl congeners including tetra‐ and pentachlorobiphenyl. bphand nahprobes from mesophilic organisms failed to hybridize to strain JF8 DNA.
