The present paper reports on the growth pattern of Dunaliella salina cells cultured
in different salinities and also in stressed conditions on exposure to
mutagens (UV and PEG). The cultures were maintained in different salinities
viz., 20, 25, 30, 35, 40, 45 and 50 ppt for a period of two weeks in triplicates and
the growth rate was monitored. The peak growth (14.29 lakhs) was observed in
35 ppt on eleventh day indicating the ideal salinity for the culture of this species.
The cultures in mid-exponential growth phase were exposed to UV light
for 30 and 60 minutes and PEG at four doses viz. 0.125, 0.25, 0.5 and 1 gm/ml.
Poorest cell growth was observed for half an hour UV treated cultures (3.51
lakhs/ml). A proportionate decrease in cell count was noticed with increase in
the concentration of PEG.
