ABSTRACT:
A method for selecting hyper-producing strains of streptovaricin C by culturing streptomyces spectabilis and separating the asporogenous colonies. The asporogenous colonies are then separately cultured and tested for streptovaricin productivity. Those colonies having the highest productivity may then be easily selected.
