ANAEROBIC BACTERIA : SAPROPHYTIC BACTERIA 103, 106 



Anaerobic and aerobic organisms — obligate and facultative anae- 

 robes — recent research in anaerobic bacteria. 



Saprophytes — putrefaction and decay — description of the commoner 

 saprophytic bacteria — principal changes that take place during 

 decomposition — putrefaction of meat — decomposition of milk by 

 bacteria — bacterial decomposition of eggs — observations on pure 

 cultures of putrefactive bacteria.
