for lactic acid bacteria, the maximal cell growth was
obtained when Lactococcus lactis cells were cultivated under
uncontrolled pH conditions. Kefiran was produced along
during the exponential growth phase which shows that kefiran
production is associated with the cell growth. The rate of kefiran
production was 0.053 g L1 h1
, which is almost likely the
same as the growth rate, where the maximal kefiran produced
reached about 1.9 g L1 at 40 h. pH increased along the cultivation
process, reaching 8.45 by the end of the cultivation.
