AbstractThe metabolic changes of carbohydrate and oil accumulation under nitrogen starvation compared to nitrogen abundant cultivation in the Chlorella sp. was investigated. The results show that after nitrogen starvation, the cell growth is inhibited, and the sp

Other Abstract以小球藻Chlorella sp.为研究对象,对比其在缺氮培养和富氮培养条件下碳水化合物和油脂积累的代谢改变。结果表明,缺氮后细胞生长受到抑制,比生长速率从正常培养的1.02d。降至0.48d^-1。细胞在缺氮第1天积累大量碳水化合物(66.9%干重),且主要以淀粉的形式存在。同时,缺氮诱导了油脂的积累,但明显落后于淀粉。通过对油脂组分的分析,发现在富氮条件下油脂的主要成分为糖脂,占总脂的51%,而缺氮后中性脂成为主要油脂组分,占总脂的87%。从原料品质角度,缺氮小球藻更适合生物乙醇和生物柴油的生产。
