我们研究了外来多毛藻贝氏branchomma bairdi体内的细菌积累和消化。对来自“未饥饿”和“饥饿”个体的蠕虫匀浆以及来自同一采样点（意大利爱奥尼亚海）的海水进行了微生物学分析。分别在Marine Agar 2216、Plate Count和TCBS琼脂上测定可培养异养细菌（22°C）、总可培养细菌（37°C）和弧菌的密度。微生物污染指标采用最可能数法确定。bairdii能够积累所有被认为的六种微生物群，然而，它们对消化的抵抗力不同。bairdib在去除细菌方面比其他两种共存的sabelld更有效，这表明它可能抵消微生物污染的影响，在环境修复中发挥潜在的作用。因此，一个潜在的风险，例如外来物种的入侵，可以转化为具有高潜在商业收益和经济可行性的利益。
We examined the bacterial accumulation and digestion in the alien polychaeteBranchiomma bairdi.Microbiological analyses were performed on worm homogenates from “unstarved” and “starved” individuals and on seawater from the same sampling site (Ionian Sea, Italy). Densities of culturable heterotrophic bacteria (22 °C), total culturable bacteria (37 °C) and vibrios were measured on Marine Agar 2216, Plate Count Agar and TCBS Agar, respectively. Microbial pollution indicators were determined by the most probable number method.B. bairdiwas able to accumulate all the six considered microbiological groups which, however, differ in their resistance to digestion.B. bairdiresults more efficient than the other two co-occurring sabellids in removing bacteria suggesting that it may counteract the effects of microbial pollution playing a potential role forin situbioremediation. Thus a potential risk, such as the invasion of an alien species, could be transformed into a benefit with high potential commercial gain and economic feasibility.
