    • Prodn. of FR-900129 comprises culturing a Streptomyces n. 4012 category which is analogous to Streptomyces misakiensis and Steptomyces aburaviensis, i.e. Streptomyces avellaneus No. 4012, at 25.degree. C. to 30.degree. C. during 50 to 100 hours in a culture medium which consists of a carbon source (e.g. glucose, fructose, glycerin, starch, galactose, maltose, dextrin), an organic or inorganic nitrogen source (e.g. yeast extract, peptone, cottonseed cake, soyabean powder, cornsteep liquor, dry yeast, ammonium nitrate, ammonium sulphate, ammonium phosphate, urea and amino acid) and an inorganic salt (e.g. calcium carbonate, sodium phosphate, potassium phosphate, sodium chloride, potassium chloride, magnesium salt and copper salt). The produced FR-900129 is isolated by a collecting step, a purifying step, a vacuum condensation step, a freeze-drying step, a pH adjusting step, a cationic, anionic or nonionic resin treating step, an active carbon adsorption step and a crystallizing and recrystallizing step. The isolated material may then be converted to its adduct salt or its ester conventionally.
    • 产品 的FR-900129包括培养Streptomyces n。 4012类似于Streptomyces misakiensis和Steptomyces aburaviensis(即Streptomyces avellaneus No.4012),在25℃至30℃下在50至100小时内在由碳源(例如葡萄糖,果糖, 甘油,淀粉,半乳糖,麦芽糖,糊精),有机或无机氮源(例如酵母提取物,蛋白胨,棉籽饼,大豆粉,玉米浸液,干酵母,硝酸铵,硫酸铵,磷酸铵,尿素和氨基酸) 和无机盐(例如碳酸钙,磷酸钠,磷酸钾,氯化钠,氯化钾,镁盐和铜盐)。 生产的FR-900129通过收集步骤,纯化步骤,真空冷凝步骤,冷冻干燥步骤,pH调节步骤,阳离子,阴离子或非离子树脂处理步骤,活性炭吸附步骤和结晶 和重结晶步骤。 然后可以将分离的材料通常转化为其加合物盐或其酯。
