Preparative amounts of purified rozeoflavin were obtained. The basic molecular methods for S .. davawensis were developed.. The effect of roseoflavin on growth of Pichia guilliermondii strains with different ability to accumulation of riboflavin was tested.. A method for positive selection of strains with an altered ability to uptake of riboflavin using rozeoflavin was proposed. Transformants with different ability to accumulation of riboflavin were obtained.
