摘要
探讨了培养温度、pH、光照、种龄、接种量以及培养时间等培养条件对破囊壶菌ThraustochytriumroseumMF2生长及其产DHA的影响。结果表明 ,T roseumMF2生长及其产DHA的适宜条件为 :培养温度 2 5℃、初始pH值 6～ 7、种龄 4 8h、接种量 4 %、培养时间 4d ,生物量达到 1 0 4g L ,DHA产量达到1 2 6 6mg L。
In this paper, effects of culture temperature, initial pH, light, inoculum age, inoculum size and culture time on the growth and DHA production of Thraustochytrium roseum MF2 were studied. The result shows that biomass reaches 10.4 g/L, DHA yield reaches 1 266 mg/L on the suitable culture conditions including culture temperature 25 ℃, initial pH 6～7, 48 h inoculum age, 4% inoculum size, and culture time 4 days.
