Table 3 Types of shoreline microbial communities observed in the studied lakes
Community type | Description | Environmental parameters | Location | Dominant species |
|---|---|---|---|---|
Algae-cyano bacterial | Abundant loose dark green or yellow-greenish communities with high numbers of Artemia sp. | Shoreline. Salinity of 150–230 g L−1, рН 7.9-8.1 | Lakes Gorkoye (41) and Solenoye (48) | Aphanocapsa sp., diatom algae |
Algae-bacterial 1 | Continuous or separate green patches | Littoral organic rich zone fertilized by cattle; large or small mat size | Lakes Dolgoye (44) and Razboynoye (46) | Filamentous green algae |
Algae-bacterial 2 | Thin easily desintegrating green layers | Littoral water-free zone, under a sand layer | Lake Krugloye (45) | Green multicellular and colonial algae |
Cyano bacterial | Felted green filamenous formations | Littoral water-free zone, under layers of sand and salt | Lakes Dolgoye (44), Krugloye, (45), and Khorosheye (47) | Scytonema sp. filamentous cyanobacterium |
Bacterial | Rosy-crimson water | Purple bacteria in little pools rich in biogenic elements under a layer of green algae | Lake Dolgoye (44) | Thiocapsa sp. purple bacterium |
