In this study, we isolated Pseudomonas sp. strain HB01 from a soil sample contaminated with brominated pollutants, and found that it degraded gamma-hexabromocyclododecane (gamma-HBCD). The strain degraded 81% of 1 mM gamma-HBCD within 5 d of culture. Furthermore, it demonstrated biodegradation of structurally related (bromo) alkanes. To the best of our knowledge, this is the first report that outlines the isolation of a bacterial strain that degrades gamma-HBCD.
在本研究中，我们从受溴化污染物污染的土壤样本中分离出假单胞菌属菌株HB01，并发现它能降解γ-六溴环十二烷（γ-HBCD）。该菌株在培养5天内降解了1 mM γ-HBCD的81%。此外，它还证明了对结构相关的（溴）烷烃具有生物降解能力。据我们所知，这是第一份概述分离出能降解γ-HBCD的细菌菌株的报告。
