Abstract
AbstractHeterotrophic CO2 fixation was measured quantitatively on the wood‐rotting fungi Armillariella mellea, Fomitopsis pinicola, Heterobasidium annosum, Phaeolus schweinitzii, Piptoporus betulinus, Trametes quercina and Chaetomium globosum. Fomitopsis pinicola showed the highest fixation activity of 19, 4 nCi/g, which corresponds to a carbon uptake of 0,253 mg/g dry matter. The values of the other organisms did not exceed 4 nCi/g DW under the same conditions.No correlation between carbon fixation activity of fungi and their taxonomic position or their nutritional requirements could be demonstrated.
