好氧生长细粒裸藻,一种漂白的突变体,在暴露于厌氧环境中时,迅速合成蜡酯,伴随着伴随的副尼龙(一种β-1,3-葡聚糖)含量的下降。将厌氧细胞带回好氧状态会导致反向转化。厌氧蜡酯的形成伴随着三磷酸腺苷的净合成。发酵和呼吸之间的转变发生在氧气浓度为10−5-10−7M时。
Aerobically grownEuglena gracilis, a bleached mutant, shows a prompt synthesis of wax esters with the concomitant fall of the paramylon (a β-1,3-glucan) content upon exposure to anaerobiosis. Bringing the anaerobic cells back to aerobiosis causes the reverse conversions. The anaerobic wax ester formation is accompanied by a net synthesis of ATP. The transition between the fermentation and respiration occurs at 10−5–10−7M of the O2concentration.
