Five species microalgae Marismopodia minima,Chlorella nana,Tetraselmis chui,Porphyridium purpureum and Rhodomonas baltica were isolated newly.Experimental results showed that in the temperature range of 10-30℃,these five algae all could survive and grow,the adaptive temperature was 15-25℃,the optimum temperature was 20-25℃.Temperature of 10℃ and 30℃ caused some decline in these algae's growth rate.The optimum temperature was 5℃ higher than those of hypotemperature species Pheaodactylum tricornutum and Isoch...
