The present study aimed to produce and characterize β-glucan from an indigenous soil isolate Bacillus cereus LVK13 (KC 898956). Thin-layer chromatography resulted an Rf value of 0.58 that corresponded to glucose. Vibrational frequencies of Fourier Transform Infrared Spectroscopy at 2885 cm-1, 1188 cm-1 and 887 cm-1 signified the existence of -CH2-, C=O bonds and β-configuration. Further, β configuration of monomeric glucose and β-(1,3)-D-glucan backbone were retrieved from the spectrum of 1H and 13C NMR. X-Ray diffraction pattern reflected low crystalline nature of the product. The results of physico-chemical analysis substantiate that β-glucan produced from the indigenous strain Bacillus cereus LVK13 can be used widely in medical, health, food and environmental sectors.
