摘要：
The aim of the study was to determine the influence of some nitrogen sources on the growth and the carotenoids accumulation in the case of several Rhodotorula sp. strains. It was emphasized that the tested nitrogen sources positively influenced the growth of the yeasts cells, as well as the concentration of total carotenoids. The highest pigments concentration was obtained in the case of medium supplemented with 0,1% glutamic acid for all tested Rhodotorula sp. strains, followed by the medium supplemented with 0,1% threonine. Only in the case of the new isolate Rd3 strain was obtained a higher value of the total carotenoids concentration on the medium with ammonium chloride as nitrogen source.
