摘要:The use of deep ocean water (DOW) for cooling purposes, as drinking water (after desalination), and in algae cultures has increased in recent years in Taiwan. This study evaluates the growth performance of Arthrospira platensis in deep ocean water (DOW), surface ocean water (SOW), and artificial ocean water (AOW) with and without a supplementary medium (BG-11). During a 14-day growth period, A. platensis had the shortest generation time (5.22 ± 0.38 days) and the highest average daily biomass yield of 0.083 ± 0.007 g/L (dry weight) in the DOW medium without supplementary BG-11. A. platensis had significant better growth rates when cultured in AOW with BG-11 than in SOW without BG-11. However, A. platensis growth rates did not differ (p > 0.05) when cultured in AOW and DOW with BG-11. The results revealed that DOW without supplementary BG-11 is a superior medium for culturing A. platensis.
