Abstract
A new apparatus was developed for measuring changes in
E
h
,
p
H, and cell numbers. With this apparatus, the relationships of these parameters were studied at initial
E
h
levels of 200 and 40 mv (
p
H 7.0), by using
Clostridium perfringens
and
Pseudomonas fluorescens
. One of the strains of
C. perfringens
grew more luxuriantly at the higher
E
h
, in the presence of small quantities of oxygen, than at the lower one in the absence of oxygen.
P. fluorescens
could grow at a relatively low
E
h
(40 mv,
p
H 7.0) in pure culture but not in the presence of
C. perfringens
under the same conditions.
