Abstract
The oxygen consumption of a starved chlorophyll-free, yellow mutant of Chlorella vulgaris is enhanced by very small amounts of blue light (lambda 450 mmu); a saturation level is reached at about 500 ergs cm(-2) sec(-1). At that intensity the respiration is about 3 times greater than in the dark. An action spectrum for the enhancement of respiration shows 2 peaks around lambda 450 and 375 mmu. Flavins and cis-carotenoids are discussed as the pigments involved.
摘要
饥饿的、不含叶绿素的、黄色的小球藻突变体的耗氧量可被极少量的蓝光（lambda 450 mmu）增强；在大约 500 尔格厘米（-2）秒（-1）时达到饱和水平。在那个强度下，呼吸作用比在黑暗中大约增加 3 倍。呼吸增强的作用光谱在 lambda 450 和 375 mmu 附近显示出 2 个峰值。黄素和顺式类胡萝卜素被认为是涉及的色素。
