The potential of rumen anaerobic fungi for fermenting untreated woods has been assessed using two Neocallimastix species isolated from sheep. When a strain of N. frontalis was incubated for 11 days with wood from 12 hardwood (angiosperm) species, many woods were measurably fermented, with wood from Populus tremuloides (32%) and Fagus sylvatica (21%) being the most highly degraded. This N. frontalis solubilised celulose, hemicellulose and lignin in P. tremuloides wood. Lower degradation (17%) of P. tremuloides wood by a different species of Neocallimastix showed that the choice of fungus as well as the structure and chemistry of the wood influenced the amount of wood cell wall degraded by anaerobic fungi. The amount of degradation was not related to the length of fungal rhizoids.
