    • PURPOSE: A novel Cystobacter sp. MSL-9 strain(KCTC 8958P) and a polymeric dispersant produced therefrom are provided, thereby the polymeric dispersant can effectively disperse clay mineral ores such as kaoline, bentonite and calcium carbonate in a liquid solution. CONSTITUTION: The novel Cystobacter sp. MSL-9 strain (KCTC 8958P) produces the polymeric dispersant which can easily disperse clay mineral ores such as kaoline, bentonite and calcium carbonate in a liquid solution. The polymeric dispersant is produced by incubating Cystobacter sp. MSL-9(KCTC 8958P) in a medium containing casitone; centrifuging the fermented culture; collecting the supernatant; adding ethanol into the supernatant; and separating the polymeric dispersant with methanol and chloroform.
    • 目的:一种新型囊状杆菌 提供MSL-9菌株(KCTC 8958P)和由其制备的聚合物分散剂,由此聚合物​​分散剂可有效地将粘土矿物如高岭土,膨润土和碳酸钙分散在液体溶液中。 构成:新型囊状杆菌 MSL-9菌株(KCTC 8958P)生产聚合物分散剂,其可以容易地将粘土矿物如高岭土,膨润土和碳酸钙分散在液体溶液中。 聚合物分散剂是通过孵育囊泡杆菌 MSL-9(KCTC 8958P)在含有中间体的培养基中; 离心发酵培养; 收集上清液; 向上清液中加入乙醇; 并用甲醇和氯仿分离聚合物分散剂。

    • PURPOSE: A Penicillium sp. F70614(KCTC 8918P) and an α-glucosidase inhibitor(diketopiperazine derivaives(formula)) are provided, which inhibits α-glucosidase effectively, so can be used for treatment and prevention of diabetes and obesity. CONSTITUTION: A process for the preparation of Penicillium sp. F70614(KCTC 8918P) and α-glucosidase inhibitor comprises the steps of: inoculating Penicillium sp. F70614(KCTC 8918P) on a prepared plate, and culturing for 3days at 28deg.C; inoculating the cultured solution in a fermentor, and culturing for 7days at 28deg.C; centrifuging the final cultured solution to separate cultured supernatant and bacillus body, extracting the bacillus body with acetone and concentrating under decompression to remove acetone, and mixing with the cultured supernatant and extracting with ethylacetate; concentrating the ethylacetate extract, and processing silicagel chromatography, LH-20 column chromatography and high-pressure liquid chromatography to get pure active ingredients; removing solvent using a decompressed dryer, and freeze-drying to get the white diketopiperazine derivaives powder(which can be also prepared by chemical synthesis).
    • 目的:青霉属 提供F70614(KCTC8918P)和α-葡糖苷酶抑制剂(二酮哌嗪衍生物(配方)),其有效抑制α-葡糖苷酶,因此可用于治疗和预防糖尿病和肥胖症。 规定:制备青霉菌的方法 F70614(KCTC 8918P)和α-葡糖苷酶抑制剂包括以下步骤:接种青霉菌 F70614(KCTC 8918P),在28℃培养3天; 将培养液接种在发酵罐中,培养7天,培养温度为28℃; 将最终培养液离心分离培养的上清液和杆菌体,用丙酮提取芽孢杆菌体,减压浓缩除去丙酮,与培养上清液混合,用乙酸乙酯萃取; 浓缩乙酸乙酯提取物,加工硅胶色谱,LH-20柱色谱和高压液相色谱,得到纯活性成分; 使用减压干燥器除去溶剂,并冷冻干燥得到白色二酮哌嗪衍生物粉末(其也可以通过化学合成制备)。
