The communities exhibited high diversity, with 655 microbial genera belonging to 34 phyla detected (31 bacterial and 3 archaeal ones). For analysis of the effect of the studied factors on community structure, a linear model was developed in order to simplify interpretation of the data of high-throughput sequencing and to obtain biologically important information. Liming was shown to modulate the effect of mineral fertilizers on the structure of microbial populations. The differences in the structure and alpha-diversity of microbial communities were shown to depend more on the crops and liming, rather than on the fertilizers applied. Interaction between the crop factor and liming expressed as an ambiguous effect of liming on the microbiome in the presence of different plants was reliably demonstrated. Thus, in the case of barley and clover, liming resulted in increased taxonomic diversity of the community, while in the case of potato and flax it had an opposite effect.</p>","PeriodicalId":18732,"journal":{"name":"Mikrobiologiia","volume":"85 2","pages":"199-210"},"PeriodicalIF":0.0,"publicationDate":"2016-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"34609455","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ratio between the biomasses of bacterioplankton (Bb) and phytoplankton (Bp) in these water bodies was shown to vary within the range exceeding three orders of magnitude. Bacterioplankton biomass was relatively stable and varied from sample to sample by an order of magnitude. In more than 50% of the samples (total sample number, 495), bacterioplankton biomass exceeded that of the phytoplankton. The average Bb/Bp ratios for Lake Khanka, Yenisei River, and Krasnoyarsk Reservoir were 5.1, 2, and 1.4, respectively. Increased Bb/Bp ratios were found to correlate with elevated specific (per unit biomass) phytoplankton production. This finding indicated additional supply of biogenic elements to phytoplankton due to their recycling by bacterial communities. The ratio between bacterioplankton and phytoplankton production for Lake Khanka varied from year to year (0.07 to 0.76). For the Yenisei River and the Krasnoyarsk Reservoir these ratios were on average 0.19 and 0.27, respectively. According to the literature data for other water bodies, bacterial production may reach from 10 to over 100% of the primary production. The equilibrium density of bacterioplankton (maximal density of the population) in Lake Khanka was ~1.5 times higher than in the Yenisei River and the Krasnoyarsk Reservoir due to higher content of suspended mineral matter and associated organo-mineral detritus in the lake.
