The unicellular alga Nannochloropsis sp. is a rich source of lipids, polyunsaturated fatty acids and carotenoids, which makes it valuable for human consumption, aquaculture and biofuel production. Mass production of Nannochloropsis sp. can be easily achieved in high-rate algal ponds (HRAP), or in flat panel photobioreactors (FPP). While easy to operate, these systems are prone to unfavorable growth conditions such as high temperature and high pH in combination with high irradiance, which affect productivity. In the present experiments, the Nannochloropsis cultures coped well with high pH conditions under physiological temperatures. However, a temperature rise above 32°C was detrimental, with repair processes being unable to keep up with the rate of damage. The cultures in the FPP were more prone to damage by extreme temperatures than those in the HRAP due to the high surface/volume ratio
