Abstract:

The metabolic heat output of resting cells (Saccharobacter fermentatus WVB8512) has been determined by means of microcalorimetric method. The metabolic thermokinetic equation is
dp/dt=k0,k0=0
The thermochemical equations are
lntm=10.1812-6.5492×10-9C
dC/dP0=KCn n=2
The order of metabolism (n) is 2. The experimental results indicate that the heat output produced by each cell and the metabolic time depend on cell concentration and are inhibited by cell density. The metabolism presents a special kind of special inhibition effect.

Key words: Resting cell, Saccharobacter Fermentatus WVB8512, Metabolism, Thermochemistry, Thermokinetics
