title: Conditions for production of 3-ketomaltose from Agrobacterium tumefaciens.
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.
