The two sets of temperature ie. 25-30°C and 30-35°C under In alternate light and dark (12:12 hr) in both the sets of temperature, ie. 25-30°C and 30-35°C, growth was higher at 25-30°C, where OD was increased 3 times the initial record and in 30-35°C, OD was only 2.8 times (Figure 1). The CC and DW also support our results (Figure 2 and 3). Higher number of cells and dry weight were observed at 25-30°C, which showed an increase of about 2.9 and 3.2 times, respectively, from the initial cultures. On the other hand, at 30-35°C the number of cells and dry weight increased only 2.7 times.

The total protein contents were directly proportionate to the growth and chlorophyll contents. Continuous light and higher temperature negatively affected protein concentration. The highest amount of protein was found in natural day light at 25-30°C i.e. 52.6% followed by
