| Abstract: | This paper presents
inhibitory effect of ethanol on growth of cells and ethanol production. A
linear fall was observed of survival (%) of Kluyveromyces Thermotolerans cells
with time. Change in death rate constant of cells beyond certain range of
ethanol concentration was due to shift in mechanism of cells inhibition.
Pronounced inhibitory effect was observed at higher ethanol concentrations in
broth. Decrease in optimum temperature for growth of cells was found with added
ethanol concentration. This also confirms more inhibitory effect of product on
microorganism at higher temperature. This study confirms both reversible and irreversible
inhibition of cells by ethanol. |
