AbstractTriacylglycerol(TAG) and starch, as the two main energy storage products in green microalgae, especially the Chlorella sp., share the same synthesis precursor in its metabolisim system. This research aimed at the key enzymes in inhibiting starch and TAG s
Other Abstract绿藻特别是小球藻细胞存在两大储碳代谢物,脂肪(TAG)和淀粉,且二者的合成享有共同的前体物质。本实验以小球藻Chlorella sp.为研究对象,在氮胁迫的条件下,抑制淀粉合成途径的关键酶和脂肪合成途径的关键酶,通过对比淀粉及脂肪的积累情况来探究两条代谢途径之间的关系。实验结果显示:加入5 mmol·L-1 Pi明显抑制了淀粉合成途径,导致淀粉含量降低,脂肪酸浓度有所增加,单位细胞脂肪酸无显著影响。加入40μmol·L-1稀禾定在第6 d表现出对脂肪的抑制,淀粉浓度降低,单位细胞淀粉含
