Abstract

The ability of 65 Trichoderma isolates to grow on 127 carbon sources was tested. Cluster analysis was performed on the basis of the data derived from the utilization of the 42 carbon sources which gave reproducible results. Partial correlation was found between the carbon source utilization patterns and previously designated species aggregates. Distinct groups within the same species aggregates consisted sometimes of strains derived from very distant geographical areas. Four groups of Trichoderma harzianum and three groups of Trichoderma hamatum could be clearly identified. Carbon source utilization appears to provide a reliable method for the identification of species within the species aggregates of the problematical genus Trichoderma.
