| 摘 要： | 由Ａｌｃａｌｉｇｅｎｅｓｌａｔｕｓ经单菌落分离，从中筛选到一株高效利用糖蜜产聚羟基丁酸（ＰＨＢ）的优良菌株１０１８。在６Ｌ台式发酵罐（Ｎ.Ｂ.Ｓ）中，进行了该菌利用甜菜糖蜜和甘蔗糖蜜积累ＰＨＢ的分批补料培养的研究。结果表明，培养５４ｈ左右发酵液中细胞干重达７０～８５ｇ／Ｌ，ＰＨＢ含量占细胞干重的６０％～７０％，生产强度１．０ｇＰＨＢ／Ｌ／ｈ以上；发酵液经非有机溶剂提取制得ＰＨＢ产品，纯度９５％，提取收率８０％以上。

| Abstract: | Production of poly (3-hydroxybutyrate ) (PHB ) by fed-batch culture of Alcaligenes latus 1018 wasinrestigated using beet and cane molasses in a 6L fermentor. In 54 hours the cell concentration and polymercontent of dry cell weight reached 70-85g / L and 60%-70%, respectively, and the productivity was up to 1.0gPHB / L / h. An aqueous digestion process was used for recovering the product from A latus with the recoveryof more than 80% and the purity of PHB was 95%. |
