 Fermentation of Bread. Katharuie E. Golden. (Bot. Gaz. xv. 



204-209). 



In this article the author describes the experiments made to 

 determine the main factor in the raising^ of bread — whether due 



to Sacckaromyees eerevisiee or Bacillus subtilis. In conclusion 

 she says: "It was demonstrated by the experiments that both 

 yeast and bacteria can sej>aratcly raise bread, and, under the con- 

 ditions of the experiments, the yeast somewhat better than the 

 bacteria. Now, whether or not they act together in raising bread 

 ordinarily was not demonstrated, but from the fact that both or- 

 ganisms were found in large quantities in dough that had been 

 raised by Fleischmann's yeast, and that bacteria are always in the 

 air and in large quantities on the surface of the grain from which 

 flour Is made, and also that they occur in all preparations of yeast 

 ferment, it seems to be the only satisfactory conclusion that both 

 the bacteria and the yeast act together in raising most if not all 



kinds of bread.*'

 the validity of the numerous species described from the territory
