| Abstract: | Streptomycete spores germinated most successfully when placed amongst hyphae of fungi that they could subsequently antagonize. The hyphae of many streptomycetes from Picea litter were able to antagonize fungi from the same habitat, but they were less effective against a group of alien fungi. Streptomycete hyphae were shown to be able to grow at the expense of antagonized fungal hyphae which suggested that they were gaining nutrients from the interaction. The fungal-streptomycete interactions were similar to interfungal hyphal interference reactions. No instances of hyphal penetration were recorded. Many bacteria from the H layer were able to lyse dead Streptomycete hyphae and they were shown to be capable of using both dead and living Streptomycete hyphae as a sole C source. Bacteria from the L and F litter layers were less active in these respects. |
