Six bacterial strains capable of using, as sole carbon and energy source, at least one of the following polycyclic aromatic hydrocarbons (PAH), naphthalene, fluorene, phenanthrene, anthracene, fluoranthene and pyrene, were isolated. The interactions between these PAH during their biodegradation were studied in experiments involving PAH pairs, one PAH at least being used as a carbon source. All individual strains were found capable of cometabolic degradation of PAH in a range varying among strains. Inhibition phenomena, sometimes drastic, were often observed but synergistic interactions were also detected. Naphthalene was toxic to all strains not isolated on this compound. Strain associations were found efficient in relieving inhibition phenomena, including the toxic effect of naphthalene. Accumulation of water-soluble metabolites was consistently observed during PAH degradation.
分离出了六种细菌菌株，它们能够将下列多环芳烃（PAH）中的至少一种作为唯一的碳源和能源，这些多环芳烃包括萘、芴、菲、蒽、荧蒽和芘。在涉及PAH对的实验中研究了这些PAH在生物降解过程中的相互作用，其中至少一种PAH用作碳源。发现所有单个菌株都能够在不同菌株间变化的范围内对PAH进行共代谢降解。经常观察到抑制现象，有时很严重，但也检测到了协同相互作用。萘对所有未在该化合物上分离的菌株有毒。发现菌株组合在缓解抑制现象方面很有效，包括萘的毒性作用。在PAH降解过程中始终观察到水溶性代谢物的积累。
