Pleurocapsales are one of the least understood groups of cyanobacteria in terms of molecular systematics and biochemistry. Considering the high number of cryptic taxa within the Synechococcales and Oscillatoriales, it is likely that such taxa also occur in the Pleurocapsales. The new genus described in our research is the first known pleurocapsalean cryptic taxon. It produces off‐flavor and a large number of bioactive metabolites (n = 38) some of which can be toxic including four known microcystins. Using a polyphasic approach, we propose the establishment of the genus Odorella with the new species O. benthonica from material originally isolated from the California Aqueduct near Los Angeles.

Biohydrogen produced from thermophilic hydrogenases is an ideal and clean energy sources. As the biggest tectonic area in the world, Indonesia is potential for thermophile isolation. The aims of this study were to analyze the bacterial diversity of a microbial mat from hot spring at Wartawan beach, Lampung and to analyze the potency of microbial mat for hydrogenases, using clone library method. The diversity of 16S rRNA showed that the microbial mat sample contained 9 phyla of bacteria, and dominated by Cyanobacteria and Proteobacteria. These p hyla indicate that the bacterial community of the microbial mat consisted of phototrophic and heterotrophic groups. In addition, a microbial mat of W artawan beach environment might be influenced by marine environment an d hydrothermal vent which was indicated by detection of both associated bacteria. The diversity of hydrogenase genes using NiFe hydrogenase (NiFe) and FeFe hydrogenase (FeFe) genes showed that Cyanobacteria was specifically related to NiFe, while Firmicutes was associated with FeFe. Proteobacteria and Bacteroidetes, however, were detected for both genes. The detected hydrogenase genes indicate that the microbial mat from hot spring at W artawan beach is a promising source for hydrogenases isolation and further applications for biohydrogen production as a renewable energy.

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.
