The specific growth rates and yields of the strains in batch culture and their germ-tube specific growth rates were at most reduced by only 18% when 2% l-sorbose was added to Vogel’s medium containing 1% sucrose. The addition of l-sorbose to solid medium induced both strains to branch profusely and resulted in the formation of dense, slow growing colonies (about 90 % reduction in radial growth rate). This reduction in the radial growth rate of spco 9 colonies could be largely correlated with a reduction (from 4·0 mm to 0·5 mm) in the width of the peripheral growth zone of colonies grown on media containing l-sorbose. Plugging of the septal pores and autolysis of hyphae of spco 9 occurred closer to the colony’s periphery when l-sorbose was present in the medium. l-Sorbose reduced the number and size of the vesicles found at the tips of hyphae of spco 9.", }
