Requirements for the rapid conversion of macroconidia of Fusarium sulphureum to chlamydospores

Chlamydospores of Fusarium sulphureum were formed within 72 h by incubating macroconidia at 37 degrees C in stationary culture in a medium containing mannitol and inorganic salts. The conversion process was dependent on inoculum level, temperature, aeration, and the presence of an external source of...

Description
Summary:	Chlamydospores of Fusarium sulphureum were formed within 72 h by incubating macroconidia at 37 degrees C in stationary culture in a medium containing mannitol and inorganic salts. The conversion process was dependent on inoculum level, temperature, aeration, and the presence of an external source of nitrogen and carbon. Chlamydospore formation was not inhibited by an uncoupler of oxidative phosphorylation, 2,4-dinitrophenol, or by inhibitors of bacterial cell wall synthesis; however, it was affected by inhibitors of respiration and of protein and chitin synthesis.
