Abstract
(1) The lactose-fermenting organisms of faeces may be divided into two groups according to the molecular ratio alcohol/acetic acid produced from glucose under specified conditions.(a) Those which produce alcohol and acetic acid in approximately equal molecular proportions.(2) Those which produce more than 2·5 molecular proportions of alcohol to 1 of acetic acid.(3) The members of the first of these groups comprise the Groups 1, 2, 3, and 4 (1) suggested provisionally by MacConkey from the consideration of the action of these organisms on cane-sugar and dulcite. The members of the second of the groups correspond with Group 4, Sub-groups 2 and 3, of MacConkey' provisiosnal classification.(4) B. lactis aerogenes acts upon glucose in a totally different manner from B. coli communis and is therefore to be regarded as a distinct organism.
