Nostoc sp. (strain Mac) was shown to be capable of using glucose, fructose, or sucrose as a sole source of carbon and energy in the dark. In the light in the absence of exogenously supplied CO(2), this strain exhibited a more versatile metabolism. In addition to the three sugars above, glycerol and acetate served as sole sources of carbon. This photoheterotrophic growth in the absence of exogenously supplied CO(2) appears to involve O(2)-evolving photosynthesis. The action spectrum for photoheterotrophic growth on acetate closely resembles the action spectrum for photosynthesis. The physiology of photoheterotrophic growth was further investigated through determinations of stable carbon isotope ratios and measurements of gas exchanges. These investigations suggest that respired CO(2) from substrate oxidation is assimilated by the photosynthetic machinery.
发菜属（菌株Mac）已被证明能够在黑暗中利用葡萄糖、果糖或蔗糖作为唯一的碳源和能源。在没有外源供应CO₂的光照条件下，该菌株表现出更具多样性的代谢。除了上述三种糖类外，甘油和乙酸盐也作为唯一的碳源。在没有外源供应CO₂的情况下这种光异养生长似乎涉及放氧光合作用。乙酸盐光异养生长的作用光谱与光合作用的作用光谱非常相似。通过测定稳定碳同位素比率和测量气体交换，对光异养生长的生理学进行了进一步研究。这些研究表明，底物氧化产生的呼吸CO₂被光合机制所同化。
