... activity for kaolin clay suspension. NaOH extraction has the highest yield, while washing extraction resulted to the lowest. The main component of the polymers obtained was protein, involving saccharide ... saccharide. These included the band corresponding to a molecular weight of 103,000 in the steaming-extracted polymer (1), the band corresponding to 38,000 in the NaOH-extracted polymer (2), the band ... respectively); in contrast, the steaming-extracted polymer included a larger amount of saccharides (24.6%) compared to the other methods. The SDS-extracted polymer included a small amount of material other...
