| Abstract: | Submerged conidiation of the entomogenous HyphomyceteBeauveria bassiana is reported. Conidiogenous cells produce sympoduloconidia on conidiogenous cells in liquid shaker culture; hyphal bodies and mycelium fragments are also produced. The morphology of these fungal structures is discussed and illustrated. Several simple liquid media are tested for the production of conidia and hyphal bodies. Maximum yields of conidia (170×106 conidia/ml) are produced in a medium consisting of sucrose (2%) — yeast extract (0.5%) and basal salts, and maximum yields of hyphal bodies (740×106 hyphal bodies/ml) in a sucrose (2.5%) — yeast extract (2.5%) medium. |
