Growth Performance Of Different Yeast Strains As Affected By PH And Sugar Concentration During Fermentation Of Sugarcane Juice
ABSTRACT
Two yeasts (Saccharomyccs cerevisiae and pichia spp)
isolates were used to ferment sugarcane juice separately for 10days at room
temperatures. While the initial pH (5.0) of one set of the juice was adjusted
using buffer solutions- Na2HPO4 and NaH2PO4
for 24h, the other set was allowed to ferment for 10days without adjusting the
pH. The yeast growth and the sugar concentration also known as the total
soluble solids (TSS) were monitored. Using the adjusted pH of 4.5 resulted in
increased growth of yeast cells with a reduction in total sugar concentration
(TSS), from 8% to 4.2%. There was a significant pH decrease in both Pichia
fermented and Saccharomyces fermented juice by day 1. The rate of sugar decrease
was faster with Saccharomyces fermented than Pichia fermented juice. There was
a gradual increase in both Saccharomyces and Pichia yeast cells fermented
juices. Pichia (3.5x105cfu/ml) inoculated juice with pH of 5.0 had
an increase in TSS by day 1. Thereafter, existed reduced TSS with gradual increase
in yeast cells until the 10thday. Sacchaminyces inoculated juice had
more TSS of 1.8% brix at the last day than Pichia.
