摘　　要：[目的]评价绿藻Chlamydomonas sp.PD-4能否作为油藻的备选藻株。[方法]研究该藻基本的生化组成以及不同培养条件下该藻的生长、油脂含量以及脂肪酸组成,并且观察该藻的气浮现象。[结果]该藻在100μmol/(m^2·s)培养9 d可产25.81%蛋白、18.82%油脂以及23.50%糖。该藻在200μmol/(m^2·s)的光以及氮浓度限制条件下培养,其油脂含量和多不饱和脂肪酸含量都会进一步提高。在较高的光强下静置培养,该藻可以自身气浮。[结论]该藻具有产油微藻的潜力。[Objective]The research aimed to evaluate the possibility as a candidate for biodiesel production of a green algae Chlamydomonas sp.PD-4.[Method]The basic bio-chemical composition,the capability in the growth,the lipid accumulation and the carbon chain composition of main fatty acid of Chlamydomonas sp.PD-4 were studied,the flotation of Chlamydomonas sp.PD-4 was also studied.[Result]The algae accumulated 25.81%protein,18.82%total lipid and 23.50%carbonhydrate after 9 d cultured in 100μmol/(m^2·s)radiation.The algae were cultured under the conditions of light of 200μmol/(m^2·s)and nitrogen concentration,and the oil content and polyunsaturated fatty acid content were further improved.The algae was cultured in a resting place at higher light intensity,and the algae could float on its own.[Conclusion]The algae is a valuable and useful oleaginous algae.
