dc.descriptionRespirometry was used to monitor the germination and growth of the entomopathogenic deuteromycete Metarhizium anisopliae on media containing carbon sources of different kinds (monosaccharides, polysaccharides, amino acids, and proteins). As also observed in several other species of fungi, M. anisopliae germination was found to be marked by a significant increase in O(2) consumption, which started a few hours before germ tube emergence. The exponential consumption of the carbon source and O(2) coincided with the exponential growth phase of the cultures. QO(2) reached a maximum value during the exponential growth phase and was drastically reduced after the depletion of the exogenous carbon source. Taking glucose as reference, we observed that casein, hydrolyzed casein, and N-acetylglucosamine accelerated germination, reduced the lag phase, and increased the growth rate. This fact demonstrates that the fungus can readily use amino acids and N-acetylglucosamine, which are the monomers of the major constituents of the insect cuticle (proteins and chitin), a property that represents an important physiological adaptation to entomopathogenicity.
