The summarized experimental data on ombrophilic bacteria isolated from dystrophic waters formed by a mycobacterial community during the process of spruce wood decomposition are presented. It was demonstrated that the ombrophilic microbial community was characterized by wide phylogenetic diversity at the initial stage of spruce wood decomposition by xylotrophic fungi under low mineralization conditions. It was noted that bacteria were able to grow under acidic and ultrafresh conditions and most of them were referred to oligotrophs. It was determined that all isolated ombrophilic bacteria divided into three groups depending on the substrate specifity: saccharolytic, acidotrophic bacteria, and bacteria, which used C1-compounds as the substrate. The position of the ombrophilic bacteria in the trophic chain was determined.
本文展示了从云杉木材分解过程中由分枝杆菌群落形成的营养不良水体中分离出的嗜雨细菌的实验数据总结。结果表明，在低矿化条件下，嗜雨微生物群落在木腐真菌分解云杉木材的初始阶段具有广泛的系统发育多样性。值得注意的是，细菌能够在酸性和超新鲜条件下生长，其中大多数属于寡营养菌。根据底物特异性，所有分离出的嗜雨细菌分为三组：分解糖类细菌、嗜酸细菌以及以C1化合物为底物的细菌。确定了嗜雨细菌在营养链中的位置。
