Investigation of endemic baikalian sponge microbiome. Baikal sponges

The endemic sponges belonged to family Lubomirskiidae are key species of macrozoobenthos in littoral of Lake Baikal. In the last 5 years, unprecedented mass death of sponges has been observed in the photic zone of the lake. Symptoms of the disease are differed (discoloration or redness of fragments or whole body of sponges, formation of necrotic ulcers, covering the individual sponge branches by sheath composed of cyanobacteria and so on) and are not associated with particular areas of the lake. The project investigates the microbiome composition associated with endemic sponges from Lake Baikal.

隶属于Lubomirskiidae科的特有海绵，是贝加尔湖沿岸带大型底栖生物（macrozoobenthos）的关键类群。近五年来，该湖透光带（photic zone）中出现了前所未有的海绵大规模死亡现象。该病害的症状呈现多样化特征，包括海绵组织片段或整体的体色褪变、泛红，坏死性溃疡形成，以及由蓝细菌（cyanobacteria）构成的鞘状物覆盖单个海绵分枝等，且病害发生与湖区特定区域并无关联。本项目旨在解析贝加尔湖特有海绵相关的微生物组（microbiome）组成。
