This work intends towards the preparation of different grades of cationic locust bean gum biopolymer (CLBG) through the incorporation of 2,3-epoxypropyltrimethylammonium chloride (GTMAC) on to the pristine locust bean gum (LBG) biopolymer. Among them the best grade was further selected, characterized and their flocculation efficacy was evaluated towards harvesting of three different indigenous isolated green microalgae viz. Chlorella sp. NCQ, Micractinium sp. NCS2 and Scenedesmus sp. CBIIT(ISM). Flocculation efficiency of 96.68%, 96.64%, and 97.42% were obtained for Chlorella sp. NCQ, Micractinium sp. NCS2 and Scenedesmus sp. CBIIT(ISM) at an optimum dosage of 55, 40, and 30 ppm respectively. Thus CLBG was proven to be an efficient flocculant towards harvesting of green microalgae than its natural form.
这项工作旨在通过在原有的刺槐豆胶生物聚合物 (LBG) 上加入 2,3-环氧丙基三甲基氯化铵 (GTMAC) 来制备不同等级的阳离子刺槐豆胶生物聚合物 (CLBG)。其中最佳等级进一步被选择、表征，并评估其絮凝效应对三种不同本土分离的绿色微藻（Chlorella sp. NCQ、Micractinium sp. NCS2 和 Scenedesmus sp. CBIIT(ISM)）的收获效果。在最佳剂量为 55、40 和 30 ppm 时，CLBG 对 Chlorella sp. NCQ、Micractinium sp. NCS2 和 Scenedesmus sp. CBIIT(ISM)的絮凝效率分别达到了 96.68%、96.64%和 97.42%。因此，CLBG 被证明是一种比其天然形式更有效的绿色微藻收获絮凝剂。
