报告了在白光或红光（>590 nm）下半连续培养中生长的 Lyngbya Plectonema、Phormidium (L.P.P.)、Fremyella dilosiphon 和 Tolypothrix tenuis 的总类胡萝卜素含量和类胡萝卜素组成。这些蓝细菌的互补色适应通过藻胆蛋白合成和类胡萝卜素合成的变化来显示。 L.P.P. 的总类胡萝卜素含量与白光相比，当细胞在红光下生长时，β，β-胡萝卜素和玉米黄质的浓度选择性增加，几乎加倍。在相同的光照条件下，F. dilosiphon 的总类胡萝卜素减少了 45%，T. tenuis 的总类胡萝卜素减少了 21%，对单个类胡萝卜素（包括酮类和糖苷类）没有显着的选择性影响。显然，L.P.P 的总类胡萝卜素含量和藻胆体大小之间存在直接关系。和 F. dilosiphon，这可能与类胡萝卜素对光敏氧化的保护作用有关。 Kezar Lake 水花束丝藻菌株（仅白光）的类胡萝卜素成分与之前的结果不同。
The total carotenoid content and carotenoid composition of Lyngbya Plectonema, Phormidium (L.P.P.), Fremyella diplosiphon and Tolypothrix tenuis grown in semicontinuous culture in white light or red light (>590 nm) are reported. Complementary chromatic adaptation of these cyanobacteria was shown by changes in phycobiliprotein synthesis and carotenoid synthesis. The total carotenoid content of L.P.P. nearly doubled with a selective increase in the concentrations of .beta.,.beta.-carotene and zeaxanthin when the cells were grown in red light as compared with white light. F. diplosiphon showed a 45% and T. tenuis a 21% reduction in total carotenoids with no significant selective effect on individual carotenoids, including ketonic and glycosidic types, under the same illumination conditions. There is apparently a direct relationhip between total carotenoid content and phycobilisome size for L.P.P. and F. diplosiphon, which may be associated with the protective effect of carotenoids against photosensitized oxidation. The Kezar Lake strain of Aphanizomenon flos-aquae (white light only) differed in carotenoid composition from previous results.
