In this study, the production and characterization of exopolysaccharide from Syncephalastrum sp. was carried out. This is the first report on the production of exopolysaccharides from Syncephalastrum sp. Totally, four different fungi (Aspergillus niger, Aspergillus flavus, Penicillium expansum and Syncephalastrum sp.) were screened for exopolysaccharide production. Among these, maximum polysaccharide producing species was selected for further large scale production. Different concentrations (6, 8 and 10%) of sucrose were also used to increase polysaccharide production. Overall results depicted that 8% of sucrose concentration exhibited higher amount of polysaccharide production. Further, structure of polysaccachride was confirmed by FT-IR and NMR spectroscopy. Based on this spectroscopy results, the polysaccharide produced by Syncephalastrum sp. was 3 linked β-D-galactopyronosyl units. The polysaccharide produced by this species composed of galactose as predominant monosccharides in the cell wall of Syncephalastrum sp. and their idealized structures were established.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
