The general conclusion is that baking does not fully 

 sterilize. The authors cultivated numerous kinds of 

 bacteria from the interior of baked loaves.

Stringy bread was found due to bacteria introduced 

 with the flour. The bacillus isolated by the author out 

 of bread and two kinds of flour is called Bacillus panis 

 viscosi (Vogel). Its cultural characters are given as 

 follows : 



It is sporiferous, actively motile, stains by Gram's 

 method, liquefies gelatin rapidly, forms a dry, gray-white 

 growth ou agar, spreads widely and is wrinkled and gray- 

 white on potato, grows in grape-sugar bouillon without 

 fas-formation, produces a thick pellicle ou peptone 

 ouillon with a clear fluid under it, and grows best at 

 40 to 42 C.

The new substratum is raw silk. Author has found a 

 bacterium which stores iron in its cell-contents. It is 

 non-motile, 2-3x0.8-2.0^, ends rounded, form plump, with 

 black polar chromatophores and intermediate gray gran- 

 ules. Many cells are entirely black and opa'que. The 

 pigment is insoluble in alcohol, ether, carbon bisulphid 

 and benzine. It becomes bluish opalescent with am- 

 monia. and bleaches with HC1, giving off hydrogen sul- 

 phid. Ou adding ferricyanide of potash after HC1, or 

 with it, ttie bacteria become an intense blue. Ou pep- 

 tone-gelatin the organism was white, but when a trace 

 of iron sulphate was added it became black.
