Two cyanobacterial strains CHAB5870 and CHAB5871 morphologically identified as Nostoc-like species were isolated from different habitats in China, and they were phylogenetically and taxonomically characterized based on a polyphasic approach combining morphological, ecological, and molecular data. In the 16S rRNA gene phylogeny inferred using maximum likelihood, maximum-parismony, and bayesian inference methods, these two strains clustered within the Pseudoaliinostoc clade. The 16S rRNA gene sequences of these two strains displayed ≥95.5% and ≤...
