Two new strains isolated from soil were identified as a new species with high biotechnological potential - Meyerella krienitzii sp. nov.
The taxonomic diversity of the algal genus Meyerella is difficult to study because of its very simple morphology. Within the Chlorella-clade Meyerella members are distinguished from the others by the absence of the pyrenoid. However, it is not possible to identify them only on the basis of light microscopy data without the involvement of molecular genetic analysis methods. Some Meyerella representatives have high biotechnological potential, because they are able to accumulate valuable metabolites, including polyunsaturated fatty acids. As a rule, water bodies are the main habitats for these green microalgae. However, strains ACSSI 428 and ACSSI 429, which described in detail in this study, were isolated from peat cryozems (Sakha Republic, Russia). In this study, a detailed comparative analysis of the morphology, phylogeny and fatty acid profiles of these strains isolated from soil and representatives of other planktonic species, primarily Myerella similis, was carried out. Based on the results obtained, it was found that the studied strains are representatives of a new species with high biotechnological potential - Myerella krienitzii sp. nov.
