Abstract

The microbial community of Baikal sponges has been studied in five species belonging to the genera Swartschewskia, Baicalospongia, and Lubomirskia of the endemic family Lubomirskiidae. The results show that the total numbers of bacteria and bacterioplankton production have an effect on the growth of L. baicalensis body. Bacteria of the genera Pseudomonas, Bacillus, Micrococcus, Sarcina, Flavobacterium, Arthrobacter, and Acinetobacter living in the sponges are representatives of the Baikal bacterioplankton. Actinomycetes of the genera Streptomyces and Micromonospora are a permanent component of the cultivable sponge microbial community. The numbers and enzyme activities of heterotrophic, oligotrophic, and psychrophilic bacteria isolated from different sponge species and the surrounding water in autumn and in winter have been estimated.

摘要

对贝加尔湖特有的卢博米尔斯基科（Lubomirskiidae）的斯瓦茨乔夫斯基属（Swartschewskia）、贝加尔海绵属（Baicalospongia）和卢博米尔斯基属（Lubomirskia）的五个物种的贝加尔湖海绵微生物群落进行了研究。结果表明，细菌总数和浮游细菌产量对贝加尔湖海绵体的生长有影响。生活在海绵中的假单胞菌属（Pseudomonas）、芽孢杆菌属（Bacillus）、微球菌属（Micrococcus）、八叠球菌属（Sarcina）、黄杆菌属（Flavobacterium）、节杆菌属（Arthrobacter）和不动杆菌属（Acinetobacter）的细菌是贝加尔湖浮游细菌的代表。链霉菌属（Streptomyces）和小单孢菌属（Micromonospora）的放线菌是可培养海绵微生物群落的永久组成部分。对秋季和冬季从不同海绵物种及周围水体中分离出的异养菌、贫养菌和嗜冷菌的数量及酶活性进行了估算。
