“…Several rare microorganisms have been found in only a few soil samples from the ancient mining regions or are present in only one sample. Among them, there are halotolerant types as Isoptericola [33], which was present in a significant amount in sample E25 (51 reads), Alitererella [26] in sample E63 (62 reads). Imperialibacter was found in samples E1 (74 reads) and E85 (36 reads).…”

Hadesarchaea and other extremophile bacteria from ancient mining areas of the East Harz region (Germany) suggest an ecological long-term memory of soil

The 16S rRNA profiling of 27 soil samples of three ancient mining areas of the East Harz region (Germany) indicated a group of rare bacteria which is related to extreme conditions such as salinity, higher temperature and alkalinity. Beside Hadesarchaea, it involves a significant number of sequences of Rubritepida, Polymorphobacter, Crinalium, Aliterella, Imperialibacter, Mizugakiibacter, Ekhidna, Mumia and Isoptericola, too. The appearance of such types may be related to the ground material which was brought onto the surface by the ancient mining activities dating back into the period between the fifteenth and the beginning nineteenth centuries. It is assumed that the RNA profiling reflects local soil bacteria communities which store a certain memory of previous environmental conditions. This ecological memory could be related on the one hand to the minerals and the mining activities centuries before, but on the other hand it could hint to the possibility of storage of bacteria in the geological sediments of late Perm (Zechstein), which has been deposited about 250 million years ago. The findings can be interpreted by the possibility of persistence of special types of soil bacteria at the ancient mining places. In addition, a possible relevance of the re-activation of very old microorganisms from deep subsurface layers for the recent microbial communities should be taken into account.

“…Our strain clusters together with the latter and a few other uncultured bacterial strains in distance to the described species A. shannxiensis , A. antarctica, and A. atlantica which could indicate a split in the genus between aquatic and terrestrial/lithophilous species. Rigonato et al (2016) as well as Zhang et al (2018) already stated that it is likely that the genus could have a broad ecological amplitude which might be clarified during future discoveries of further species that belong to this genus. However, both author teams proposed the new monotypic family Aliterellaceae within the order Chroococcidiopsidales to accommodate this genus, which is supported by our data.…”

“…In contrast to morphologically distinct heterocytous cyanobacteria, coccoid unicellular species such as the recently established genus Aliterella lack even more morphological characters (Rigonato et al 2016). This genus comprises the three aquatic species A. atlantica, isolated from the water column of the Atlantic close to south‐east Brazil, A. antarctica, found in a green turf alga from coastal Antarctica (Rigonato et al 2016), and finally A. shaanxiensis isolated from water samples of a freshwater inland lake in Shaanxi, China (Zhang et al 2018).…”

The polyphasic approach has been widely applied in cyanobacterial taxonomy, which frequently led to additions to the species inventory. Increasing our knowledge about species and the habitats they were isolated from enables new insights into the ecology of newly established genera and species allowing speculations about the ecological niche of taxa. Here, we are describing three new species belonging to three genera that broadens the ecological amplitude and the geographical range of each of the three genera. Cyanocohniella crotaloides sp. nov. is described from sandy beach mats of the temperate island Schiermonnikoog, Netherlands, Oculatella crustae-formantes sp. nov. was isolated from biological soil crusts of the Arctic Spitsbergen, Norway, and Aliterella chasmolithica originated from granitic stones of the arid Atacama Desert, Chile. All three species could be separated from related species using molecular sequencing of the 16S rRNA gene and 16S-23S ITS gene region, the resulting secondary structures as well as p-distance analyses of the 16S-23S ITS and various microscopic techniques. The novel taxa described in this study contribute to a better understanding of the diversity of the genera Cyanocohniella, Oculatella, and Aliterella in different habitats.

Cyanobacteria are photosynthetic organisms that produce a large diversity of natural products with interesting bioactivities for biotechnological and pharmaceutical applications. Cyanobacterial extracts exhibit toxicity towards other microorganisms and cancer cells and, therefore, represent a source of potentially novel natural products for drug discovery. We tested 62 cyanobacterial strains isolated from various Brazilian biomes for antileukemic and antimicrobial activities. Extracts from 39 strains induced selective apoptosis in acute myeloid leukemia (AML) cancer cell lines. Five of these extracts also exhibited antifungal and antibacterial activities. Chemical and dereplication analyses revealed the production of nine known natural products. Natural products possibly responsible for the observed bioactivities and five unknown, chemically related chlorinated compounds present only in Brazilian cyanobacteria were illustrated in a molecular network. Our results provide new information on the vast biosynthetic potential of cyanobacteria isolated from Brazilian environments.
