Abstract
Cyanobacteria are immense sources of several pharmacological compounds such as flavonoids and carotenoids with anti-inflammatory and antioxidant activity. Two novel cyanobacterial isolates were isolated and identified by sequencing of 16S rRNA gene. The results revealed that the two isolates are Sphaerospermopsis aphanizomenoides (KU212886.1) and Cronbergia siamensis (KY296358.1). The BLAST alignment showed that the nearest NCBI deposited sequences were Cronbergia siamensis (NR153750.1) to C. siamensis (KY296358.1) and Sphaerospermopsis aphanizomenoides (LN846950.1) to S. aphanizomenoides (KU212886.1) with identity ratio 94% and 93%, respectively. The phylogenetic trees confirmed the same identity ratios on the roots of clades. The two newly identified isolates could be new species with novel and unique characteristics.
