“…The polyphasic taxonomy applied to the strains of this study revealed taxa known to be part of bloom-forming communities ( Sphaerospermopsis and Nodularia), rock-dwelling communities ( Scytonema and Tolypothrix ), and hot spring cyanobacteria mats ( Desertifilum and Gloeotrichia ) (Dadheech et al, 2014; Mazur-Marzec et al, 2015; Gkelis et al, 2017; Joanna and Andrzej, 2018). Our results revealed the presence of taxa not previously described from Greek habitats (Gkelis et al, 2016), such as Allinostoc (Saraf et al, 2018) and Oculatella (Osorio-Santos et al, 2014) and taxa previously described only from the tropical zone like Komarekiella and Kovacikia (Miscoe et al, 2016; Hentschke et al, 2017). Furthermore, the Geitleria calcarea strain isolated in this study, to the best of our knowledge, is the first isolate in world’s cyanobacteria culture collections depositories (Friedmann, 1979; Coute, 1989), whilst Chlorogloea sp.…”

Cyanobacteria have been linked with hydrogen cyanide, based on their ability to 9 catabolize it by the nitrogenase enzyme, as a part of nitrogen fixation. Nitrogenase can also use 10 hydrogen cyanide instead of its normal substrate, dinitrogen and convert it to methane and 11 ammonia. In this study, we tested whether cyanobacteria are able, not only to reduce, but also to 12 produce HCN. The production of HCN was examined in 78 cyanobacteria strains from all five 13 principal sections of cyanobacteria, both non-heterocytous and heterocytous, representing a variety 14 of lifestyles and habitats. Twenty-eight (28) strains were found positive for HCN production, with 15 universal representation amongst 22 cyanobacterial planktic and epilithic genera inhabiting 16 freshwater, brackish, marine (including sponges), and terrestrial (including anchialine) habitats. The 17 HCN production could be linked with nitrogen fixation, as all of HCN producing strains are 18 considered capable of fixing nitrogen. Epilithic lifestyle, where cyanobacteria are more vulnerable to 19 a number of grazers and accumulate more glycine, had the largest percentage (75%) of 20 HCN-producing cyanobacteria compared to strains from aquatic ecosystems. Further, we 21 demonstrate the isolation and characterisation of taxa like Geitleria calcarea and Kovacikia 22 muscicola, for which no strain existed and Chlorogloea sp. TAU-MAC 0618 which is, to the best of 23 our knowledge, the first bacterium isolate from anchialine ecosystems. Our results highlight the 24 complexity of cyanobacteria secondary metabolism, as well as the diversity of cyanobacteria in 25 underexplored habitats, providing a missing study material for this type of environments.26

“…In the 16S rRNA gene tree, strains SA18, SA24 and SA30 clustered within the Aliinostoc clade. Out of the three strains, SA30 isolated from a paddy field clustered strongly with Aliinostoc soli ZH1(3)_PS a soil dwelling strain from India [12] and Aliinostoc tiwarii LI PS a freshwater strain also reported from India [12] (Fig. 2a).…”

“…While morphological, molecular and phylogenetic evidence were strong indicators of the taxonomic positioning and novelty, to further ascertain the taxonomic status of our strains, we performed the 16S-23S ITS folded secondary structure analysis as it has been reported to be an effective tool in differentiating the members of the genera Aliinostoc, Desmonostoc and Desikacharya [4,6,12,[23][24][25]. Secondary structures corresponding to the D1-D1′ helix region and BoxB region were obtained for all the members of the genus Aliinostoc.…”

“…The genus Aliinostoc, the members of which showed morphological characters similar to members of the true Nostoc, was described by Bagchi et al [4] on the basis of its distant phylogenetic positioning from Nostoc sensu stricto. At present, majority of the strains of the genus Aliinostoc have been reported from tropical regions, except strains PCC 8122 and PCC 8976 that were reported from USA and France respectively [10][11][12]. The members of the genus Aliinostoc are usually found in habitats that are rich in dissolved salts and ions.…”

Five cyanobacterial strains with Nostoc -like morphology from different localities of the Mazandaran province of Iran were characterized using a polyphasic approach. Three strains clustered within the Aliinostoc clade whereas one each of the remaining two strains clustered within the genera Desmonostoc and Desikacharya . The phylogenetic positioning of all the strains by the bayesian inference, neighbour joining and maximum parsimony methods inferred using 16S rRNA gene indicated them to represent novel species of the genera Aliinostoc , Desmonostoc and Desikacharya . The 16S–23S ITS secondary structure analysis revealed that all five strains under study represented novel species unknown to science. In accordance with the International Code of Nomenclature for algae, fungi and plants we describe three novel species of the genus Aliinostoc and one species each of the genera Desmonostoc and Desikacharya .

This survey of 2018 literature on substratum-associated microbiota presents brief highlights on research findings from primarily freshwaters, but includes those from a variety of aquatic ecosystems. Coverage of topics associated with benthic algae and cyanobacteria, though not comprehensive, includes new methods, taxa new to science, nutrient dynamics, trophic interactions, herbicides and other pollutants, metal contaminants, nuisance, bloom-forming and harmful algae, bioassessment, and bioremediation. Coverage of bacteria, also not comprehensive, focused on methylation of mercury, metal contamination, toxins, and other environmental pollutants, including oil, as well as the use of benthic bacteria as bioindicators, in bioassessment tools and in biomonitoring. Additionally, we cover trends in recent and emerging topics on substratum-associated microbiota of relevance to the Water Environment Federation.
