[en] 4845. Weizmann, C. March 29. Fuseloil organized ferments.-Acetone and alcohol particularly butyl alcohol, are obtained by fermentation under aerobic or anaerobic conditions of carbohydrate material such as maize, rice, wheat, oats, rye, dari, and potatoes, with a culture of the bacteria which are found in soil or on cereals such as maize, rice, and flax, and which survive heating to 90-100 C. for one to two minutes. The bacteria will also liquefy gelatine and are stated to be probably bacillus granulobacter pectinovorum. The cultures may be prepared by inoculating sterile maize-mash heated to 90-100 C. with maize-meal, and allowing the mixture in divided portions to ferment at 35-37 C. The culture which shows the most vigorous fermentation and has the most pronounced smell of butyl alcohol is heated to 90- 100 C. for one to two minutes and used to inoculate a sterile maize-mash. This process of preparing sub-cultures is repeated about 100 to 150 times.
