摘要
阐述了生物膜系统中与降解基因有关的水平基因转移的研究进展,表明生物膜中致密的群落结构增加了细菌间水平基因转移的效率.近年发展起来的研究策略和新的分子生物学方法使人们能对自然和人工模拟状态下的水平基因转移进行更精细的分析,降解基因在环境中的水平传播促进了难降解有机物的生物降解,尤其是携带降解基因的接合质粒向原位细菌种群中的转移在生物强化中具有巨大的潜力.
This paper reviews the research of horizontal gene transfer (HGT) related to catabolic gene in biofilms system, and indicts that the dense community structure in biofilms increases the efficiency in horizontal gene transfer among bacteria. The development of research strategies and novel molecule methods in recent years have made a more careful analysis of HGT possible under natural and artificial conditions. Furthermore, horizontal transfer of catabolic gene in environment enhances biodegradation of recalcitrant organic compounds. Particularly, the delivery of catabolic gene information of conjugative plasmids to bacterial population in situ has great potential in bioenhancement. Ref 23
