Abstract

Up to 39% yields of 3-ketomaltose were achieved in 18 to 22 hr when Agrobacterium tumefaciens NRRL B-36 was cultured at 25 to 28 C in a simple medium containing 4.0 to 8.0% maltose, 0.09% urea, 0.5% CaCO(3), 0.6% KH(2)PO(4), and 0.025% MgSO(4).7H(2)O. For maximum production of 3-ketomaltose the culture had to be maintained approximately at pH 7.0.

摘要

当根癌土壤杆菌NRRL B - 36在含有4.0%至8.0%麦芽糖、0.09%尿素、0.5%碳酸钙、0.6%磷酸二氢钾和0.025%七水硫酸镁的简单培养基中于25至28℃培养时,在18至22小时内可获得高达39%的3 - 酮麦芽ose产量。为了使3 - 酮麦芽ose产量最大化,培养物必须维持在约pH 7.0。
