Nineteen numerically dominant heterotrophic bacteria from a freshwater biofilm were identified by 16S ribosomal DNA gene sequencing, and their coaggregation partnerships were determined. Phylogenetic trees showed that both distantly related and closely related strains coaggregated at intergeneric, intrageneric, and intraspecies levels. One strain, Blastomonas natatoria 2.1, coaggregated with all 18 other strains and may function as a bridging organism in biofilm development.
通过16S核糖体DNA基因测序鉴定了来自淡水生物膜的19种数量占优势的异养细菌,并确定了它们的共聚集伙伴关系。系统发育树表明,远缘和近缘菌株在属间、属内和种内水平上都有共聚集现象。一株菌株,即游泳芽单胞菌2.1,与其他18株菌株都有共聚集现象,可能在生物膜形成过程中起到桥梁作用。
