Several pigments (beta-, gamma-carotenes and lycopene) have been isolated from the culture of the mutant strain of Actinomyces sp. 2 var. PIII related to Actinomyces chrysomallus. The pigments were identified by the position of maxima and absorption of light by the pigments within the range of 400 to 520 nm, and also by chromatography in several solvent systems, the results were compared with standard samples and literature data. The total yield of the carotenes during cultivation in flasks was 0.744 mg/g of dry mycelium; the content of beta-carotene was 0.590 mg/g.
已从与金色放线菌相关的放线菌属2变种PIII突变菌株的培养物中分离出几种色素（β-、γ-胡萝卜素和番茄红素）。通过色素在400至520nm范围内的最大吸收位置以及光吸收来鉴定这些色素，并且还通过在几种溶剂系统中的色谱法进行鉴定，将结果与标准样品和文献数据进行比较。在烧瓶中培养期间胡萝卜素的总产量为0.744mg/g干菌丝体；β-胡萝卜素的含量为0.590mg/g。
