||||||||||AK103 / Akesobio, Taizhou Hanzhong Biopharma Journal: Purification, characterization and functional properties of exopolysaccharide from a novel halophilic Natronotalea sambharensis sp. nov. (Pubmed Central) - Jan 1, 2020 An exopolysaccharide producing strain AK103 was isolated from Sambharlake, Rajasthan, India...Interestingly, the EPS was found to have antioxidant activity and in vitro antioxidant studies showed that DPPH (2,2-diphenyl-1-picrylhydrazyl) activity increased in a dose dependent manner. Furthermore, EPS Nat-103 was able to produce gold nanoparticles which were further characterized by FT-IR, DLS and Zeta potential (ZP).
