Abstract
553,465. Vitamins ; butyl alcohol and acetone. COMMERCIAL SOLVENTS CORPORATION. Nov. 13, 1940, No. 16445. Convention date, Oct. 24. [Class 2 (iii)] [Also in Group VI] In the fermentation of carbohydrate mashes to produce riboflavin together with butyl alcohol and acetone, particularly by means of Clostridium acetobutylicum (Weizmann), the operation is effected with precautions to reduce or exclude the presence of iron, nickel, cobalt, copper, lead and zinc. The amount of these metals or their compounds permitted should be not more and preferably much less than one tenth of the amount which would substantially reduce the yield of solvents. To effect this the grain used may be cleaned by blowing, or the grain or meal subjected to magnetic separation and materials containing these metals, such as molasses, avoided. Condensed steam which has passed through iron pipes and the use of iron vessels in contact with the wash should be avoided, but the precautions are less necessary after the " acid break." The apparatus may be of aluminium or its alloys, and it is stated that small quantities of aluminium in the mash may improve the yield of riboflavin. Examples describe the effects of various small quantities of the specified metals on the yields of riboflavin and solvents. Specification 527,478 is referred to.
