초록

The biopolymer produced by Lysinibacillus macroides can be useful as an emulsifying agent, flocculating agent, anti-oxidative agent, and anti-corrosive agent. The present work focused on the functional activities of this biopolymer such as bioflocculant and anti-corrosion. The results of the study for the biopolymer as a bioflocculating agent reveal that the biopolymer gave 72.3% flocculating activity against activated carbon at a concentration of 5 mg/l. In the optimization study, the highest bioflocculant activity was obtained in the presence of CaCl2 mineral at 15% biopolymer concentration, 7.0 pH, and 40℃ temperature. The biopolymer was also studied for its anti-corrosive nature and observed that it was able to prevent corrosion of steel paper clips in a 6% CaCl2 solution at a concentration of 0.5% after 7 days.
