The number of microorganisms and bacterial biomass in ooze deposits of the Ivano-Arakhleyskiye Lakes (Zabaikalye) decrease unevenly downward the ground column. This decrease is more sharp near the shores. The total number and bacterial biomass of the ground microflora directly depend on the extent of trophicity of the lakes. Gas production in the lakes Irgen, Ivan and Arakhley is accomplished by bacteria and involves exocellular enzymes. The rate of gas production differs among the lakes, along their horizontal layers, and in the vertical cross-section of sediments. The technique for determining the rate of gas production proposed by M. A. Messineva has been successive when applied to the ground of the Ivano-Arakhleyskiye Lakes.
伊万诺-阿拉赫列伊斯克湖（外贝加尔地区）软泥沉积物中的微生物数量和细菌生物量沿地柱向下不均匀减少。这种减少在岸边附近更为明显。底层微生物群落的总数和细菌生物量直接取决于湖泊的富营养化程度。伊尔根湖、伊万湖和阿拉赫列伊湖的产气过程由细菌完成，并涉及胞外酶。不同湖泊之间、沿其水平层以及沉积物垂直剖面的产气速率各不相同。M. A. 梅斯涅娃提出的测定产气速率的技术应用于伊万诺-阿拉赫列伊斯克湖的底层时是成功的。
