halotolerant yeast, Debaryomyces nepalensis was studied by growing
cells in shake flask on rotary shaker and cell growth was measured. Specific
growth rate (μ) of D. nepalensis increased with increase in
temperature from 15 to 35 °C and then decreased with increase in temperature
beyond 35 °C when grown in presence and absence of different salts.
At 40 °C, both NaCl and KCl at 1.0 M concentration enhanced the specific
growth rate. D. nepalensis showed synergistic effect on thermal
and salt stress when grown at 35-40 °C (0.5 M NaCl) and 30-40 °C
(0.5 and 1.0 M KCl). The organism was able to revert its specific growth
rate when temperature was shifted from 20 °C to its optimum temperature
for growth (30 °C) only in the presence of salts, which was not observed
in the absence of salts. However, the same phenomenon was not observed
when the temperature was shifted from 40 to 30 °C. Decrease in activation
energy was observed for growth at salt concentration beyond 0.5 M of NaCl
and KCl.]]>Almagro, A., C. Prista, S. Castro, C. Quintas, A. Madeira, J. Ramos and M.C.
