FIG. 6 in Fungal/bacterial syntrophy of glycerol utilization

FIG. 6. — Production of perithecia by Podospora anserina (Rabenh.) Niessl in the presence of Paenibacillus validus (Nakamura) Ash et al. and Escherichia coli T.Escherich. The presence of large amounts of mature perithecia (the black dots) are seen around and farther away from the bacterial colony on media containing 0.02 M glycerol. The fungus formed a dense mycelium on a plate containing 0.1 glycerol and the bacteria. Note that at 0.1 M glycerol, P. anserina remained sterile even in the presence of bacteria. Scale bars: 250 µm.
