在这项研究中，我们评估了真核游动孢子的发展（形成，的士和解决）下不同制度的暴露于多环芳烃（PAHs），模仿环境污染和生物修复的情况。为此，我们使用卵菌，腐霉aphanidermatum，作为游动孢子和两个PAH降解细菌（分支杆菌gilvumVM 552和PseudomonasputidaG 7）的来源。卵菌和两种细菌不具有拮抗性，游动孢子的形成仅在最高细菌细胞密度（108- 1010个菌落形成单位mL− 1）存在时才减少。当多环芳烃与有机溶剂和极性溶剂接触时，多环芳烃对游动孢子的形成和趋性有负面影响。多环芳烃与非极性溶剂[十六烷（HD）和2，2，4，4，6，8，8-七甲基壬烷（HMN）]的共暴露不影响游动孢子在有机溶剂和水的界面处的沉降。然而，游动孢子解决和创建菌丝体网络只在HD-水界面。这两种细菌减少了多环芳烃的游动孢子的形成和的士的毒性影响，他们没有中断游动孢子定居。结果表明，游动孢子发育可用于多环芳烃的毒性评价和提高其生物有效性。在游泳模式和社区形成污染物界面的微生物相互作用被揭示的主要因素，具有潜在的相关性，生物修复。
In this study, we assessed the development (formation, taxis and settlement) of eukaryotic zoospores under different regimes of exposure to polycyclic aromatic hydrocarbons (PAHs), which imitated environmental scenarios of pollution and bioremediation. With this aim, we used an oomycete,Pythium aphanidermatum, as a source of zoospores and two PAH-degrading bacteria (Mycobacterium gilvumVM552 andPseudomonasputidaG7). The oomycete and both bacteria were not antagonistic, and zoospore formation was diminished only in the presence of the highest bacterial cell density (108–1010colony-forming units mL− 1). A negative influence of PAHs on zoospore formation and taxis was observed when PAHs were exposed in combination with organic solutions and polar solvents. Co-exposure of PAHs with non-polar solvents [hexadecane (HD) and 2,2,4,4,6,8,8-heptamethylnonane (HMN)] did not affect zoospore settlement at the interfaces of the organic solvents and water. However, zoospores settled and created mycelial networks only at HD–water interfaces. Both bacteria diminished the toxic influence of PAHs on zoospore formation and taxis, and they did not interrupt zoospore settlement. The results suggest that zoospore development could be applicable for toxicity assessment of PAHs and enhancement of their bioavailability. Microbial interactions during both swimming modes and community formation at pollutant interfaces were revealed as major factors that have potential relevance to bioremediation.
