It was first reported common to a number of Leuconostoc by Johnson! that Leuconostoc mesenter­ group organisms and that this mayor oides 9135, though requiring nicotinic may not be coupled with inability to acid, did not respond to ordinary grow in the presence of DPN. A number amounts of rucotrnamide or nicotinuric of other experiments dealing with the acid.
