摘要
选取了6种微藻(包括3株绿藻、2株硅藻和1株金藻),考察了其在不同外加碳源下的异养能力,以及不同培养方式下的生长及产油情况。结果表明:除小新月菱形藻外,其余5株藻均可异养,然而外加碳源对其影响大小不同。筛选出1株小球藻和1株栅藻,其兼养时油脂产率分别达到102.48和129.13 mg/(L.d),是自养组油脂产率的6倍和8倍,可进一步优化培养条件以期作为生物柴油原料。
Total six microalgae species,including 3 strains of green algae,2 strains of diatoms and 1 strain of Isochrysis galbana,were chosen for this study.Differences of heterotrophic capability,growth and lipid production yield from various cultivation methods to these microalgae strains were compared.The results show that,except Nitzschia closterium,the other five strains could be cultured in hererotrophy.But the influences of external carbon source on growth of these algae strains are different.Aiming at oil yield,one strain of Chlorella sp.and one strain of Scenedesmus obliquus were screened out.Their oil production yields in mixotrophy cultivation conditions were of 102.48 and 129.13 mg/（L.d）,respectively,six and eight times higher than those in autotrophy conditions,which can be used as an new resource for biodiesel producing,meanwhile,further probablecultivation condition optimization are required.
