Effect of the endogenous phase duration on the maximum substrate removal rate in mixed cultures
The maximum substrate removal rates, r x, m , were measured during the endogenous phase by means of a simple respirometric method. Excess biomass from a continuously-fed completely mixed (CM) and a semicontinuously-fed (SE) reactor was tested with ethylalcohol, glutamic acid, phenylalanine, acetic a...

| description | The maximum substrate removal rates,
r
x,
m
, were measured during the endogenous phase by means of a simple respirometric method. Excess biomass from a continuously-fed completely mixed (CM) and a semicontinuously-fed (SE) reactor was tested with ethylalcohol, glutamic acid, phenylalanine, acetic acid, phenol and glucose. It was found with the mixed culture from the CM system that during a 6-h endogenous period, the
r
x,
m
values remained constant with all the substrates tested. With the mixed culture from the SE system, the
r
x,
m
values increased during first 8–12 h of the endogenous period and then decreased. The authors conclude that the respirometric method measuring
r
x,
m
values can be used to optimize the contact stabilization process. |
