Abstract:
In this study, Dunaliella viridis was isolated
from Çamalti salt work and its growth rate, cell density, chlorophyll-a
and total carotenoids content were studied in a batch system. This strain
was cultured at different NaCl concentrations (1, 2 and 3M), different
temperatures (25 and 28°C) and different light intensities (50 and
75 μmol photon/m2/sec). In this experiment, maximum growth
rate was at 2 M salinity with 28°C temperature and 50 μmol photon/m2/sec
light intensity. Maximum cell density for D. viridis was obtained
at 25°C, 50 μmol photon/m2/sec, 2M cultures. The highest
chlorophyll-a and total carotenoids were calculated as 2.84±0.50
and 1.11±0.05 pg cell-1, respectively. The optimum temperature
and salinity for growth of D. viridis strain were around 25°C
and 2 M NaCl. The present study shows that cell densities and pigment
yields of D. viridis Çamalti strain are strongly dependant
on salinity, temperature and light intensity.
