Abstract: 

During their natural life cycle most fungi encounter other microorganisms and live in mixed communities with complex interactions, such as symbiosis or competition.  Industrial fermentations, on purpose or by accident, can also result in mixed cultures.  Fungal co8208;cultivations have been previously described for the production of specific enzymes, however, little is known about the interactions between two species that are grown together.  A. niger and A. oryzae are two of the most important industrial fungi worldwide and both have a long history of strain improvement to optimize enzyme and metabolite production. Co8208;cultivation of these two Aspergilli with each other and with the ascomycete phytopathogen Magnaporthe grisea, and the basidiomycete white rot fungus Phanerochaete chrysosporium, has recently been described by our group (Hu et al, 2010). Total secreted protein, enzymatic activities related to plant biomass degradation and growth phenotype were analyzed from cultures on wheat bran demonstrating positive effects of the co8208;cultivation compared to the individual cultivations. In a follow8208;up study the morphology and mechanism of the interaction is addressed using microscopy and proteomics. Data from this study will be presented.   Reference Hu et al.
