Factor analysis was applied to batch shake-flask fermentations for the production of
the enzyme cytochrome p-450 by the yeast Saccharomyces cerevisiae NCYC. 754 on a
medium based on coconut-water allowing a screening of the experimental variables
temperature (T), pH, shaking rate (RPM) and the initial concentrations of glucose
(G), yeast extract (YE), peptone (P) and phosphoric acid (PA)supplements. Both the
enzyme specific yield (nmol g-1) and the biomass yield (gL-1) were found to be strongly
influenced by all the above experimental variables except P. Previous media
formulations for the fermentation have shown that peptone is very important in
ensuring good growth and enzyme production. The possibility of formulating a
coconut-water based medium which needs less peptone supplement would lower
medium costs as well as partly solve the wastewater treatment problem of the coconut
processing plants |
