Abstract

D-erythro-C₁₄-Sphingosine (C₁₄-Sph) accelerated the germination of Nomuraea rileyi in a solution containing peptone, but activity declined to a large degree in water. This suggests the presence of a co-factor in C₁₄-Sph-triggered germination. Since the main role of peptone is to supply nitrogen constituents, we examined the effects of various nitrogen constituents. It was found that Ala and His were highly effective for C₁₄-Sph-triggered germination.
