Abstract
A new water-soluble photochromogenic fluorescent violet pigment with the indicator properties was isolated from the culture fluid of Nocardia fructiferi var. ristomycini, strain 76. By its solubility and mobility in various solvent systems and by the absorption spectrum the new pigment is close but not identical to such a pigment as rubrocyanin. The presence of microelements, i.e. iron and magnesium in the medium was shown to be necessary for production of violet pigment.
摘要
从果糖诺卡氏菌里氏霉素变种76号菌株的培养液中分离出一种具有指示特性的新型水溶性光致变色荧光紫色色素。根据其在各种溶剂系统中的溶解度和迁移率以及吸收光谱，这种新色素与诸如红铜蓝蛋白之类的色素相近但并不相同。结果表明，培养基中微量元素即铁和镁的存在对于紫色色素的产生是必需的。
