Bacteria in the water-saturated sand of a relatively unpolluted sand beach were enumerated by direct microscope and viable counting. The number of interstitial bacteria was estimated to be a significant fraction of the total number of bacteria present. Three hundred sixty-two strains were isolated and submitted to cultural and biochemical tests. Fermentational abilities and the production of indole suggested that a significant number of these bacteria were symbiotically associated with resident metazoans.
通过直接显微镜检查和活菌计数法对相对未受污染的沙滩中饱水沙子里的细菌进行了计数。间隙细菌的数量估计占所存在细菌总数的很大一部分。分离出362株菌株,并进行了培养和生化测试。发酵能力和吲哚的产生表明,这些细菌中有相当数量与栖息的后生动物共生相关。
