- 論文の詳細を見る
Poly(γ-glutamic acid)(γ-PGA) prepared from a culture fo Bacillus subtilius had a high flocculating activity and its flocculation properties were investigated. Flocculating activity of γ-PGA in a kaolin suspension was stimulated by the addition of Ca^<2+>, Mg^<2+> or Fe^<2+> to the suspension. High flocculating activity of γ-PGA was induced in a kaolin suspension by addition of Fe^<3+> or Al^<3+> and pH adjustment to the neutral range. Various inorganic suspensions of active carbon, acid clay, solid soil, and calcium and magnesium compounds were flocculated by γ-PGA. Flocculation of organic suspensions such as cellulose and yeast by γ-PGA occurred when Fe^<2+>, Fe^<3+> or Al^<3+> were added and the pHs of the suspensions were adjusted to the neutral range. From these flocculation properties in various suspensions, it may be possible to use γ-PGA as a new biodegradable, harmless biopolymer flocculant.
