OPTIMIZATION AND CHARACTERIZATION OF LIPOPEPTIDE BIOSURFACTANT
Dr. Priya Iyer, P. Sandhya
Abstract :
Lipopeptides are the bioactive peptides and some constituents of these compounds are surfactin, fengycin, iturins, mycosubtilins and bacillomycins. Among these lipopeptides, surfactin is produced by Bacillus subtilis that has strong anti–microbial,anti–viral and anti–larvicidal activities. In the present study, Bacillus spp. was chosen for lipopeptide production and the growth medium used was whey + mineral salt media. The optical density of the growth medium was checked for 72 and 96 hours and the best results were observed in 72 hour culture; thus chosen for lipopeptide production.The biomass and the crude obtained were estimated to be 21.72 g/L and 5.0 g/L respectively. The crude obtained was characterized for its surfactant molecule using MALDI–MS and FTIR. MALDI–MS showed the highest peak of 1029.8 at the intensity of 69.4 indicating the presence of surfactin molecule. FTIR also proved the presence of surfactin
