Response of two cyanobacterial strains to non-biodegradable glitter particles.

Microplastic pollution is a growing concern mainly in aquatic environments due to its deleterious effects. Some types of microplastics, such as glitter, remain overlooked. Glitter particles are artificial reflective microplastics used by different consumers within arts and handcraft products.

The cyanobacterial genus is an important contributor to carbon and nitrogen bioavailability in terrestrial ecosystems and a frequent partner in symbiotic relationships with non-diazotrophic organisms. However, since this currently is a polyphyletic genus, the diversity of -like cyanobacteria is considerably underestimated at this moment. While reviewing the phylogenetic placement of previously isolated -like cyanobacteria originating from Brazilian Amazon, Caatinga and Atlantic forest samples, we detected 17 strains isolated from soil, freshwater, rock and tree surfaces presenting patterns that diverged significantly from related strains when ecological, morphological, molecular and genomic traits were also considered.

Phylogenomic analysis of (Nostocales, Cyanobacteria).

The saline-alkaline lakes (soda lakes) are the habitat of the haloalkaliphilic cyanobacterium , the type species of this genus. To obtain robust phylogeny of this type species, we have generated whole-genome sequencing of the bloom-forming strain CCIBt3563 isolated from a Brazilian soda lake. This strain presents the typical morphology of with short and curved trichomes with apical heterocytes established after separation of paired intercalary heterocytes and also regarding to cell dimensions.
