ABSTRACT: β-Glucan, a homopolymer of glucose which contains mainly β-(1,3)-d-glucan, was extracted from Bacillus cereus LVK13 using ethanol precipitation. β-glucan was considerably privileged for its biological importance on comparison with other polymers. As oxidative stress is contemplated to be one of the fundamental causative for various diseases and aging, the antioxidant activity of β-glucan was investigated to estimate hidden unfamiliar perks associated with β-glucan in this study. This survey was shaped to compare the scavenging effect of β-Glucan from Bacillus cereus LVK13 with that of synthetic antioxidants like ascorbic acid and butylated hydroxyl toluene via DPPH (2,2-diphenyl-2-picryl hydrazyl) radical scavenging assay. The result of this study showed that isolated β-Glucan extract of Bacillus cereus LVK13 possesses significant antioxidant properties
