Carbohydrate Nutrition of some Nematode-trapping Fungi

ALTHOUGH the predaceous habit of the nematode-trapping Hyphomycetes has aroused wide interest the physiology of species within this group remains relatively unexplored. It has been suggested that during the decomposition of organic matter in the soil these fungi are capable of trapping nematodes only while suitable carbon sources are available to provide energy for growth1,2. In general, they may be divided into two contrasting ecological groups. The first, typified by species forming adhesive networks, are comparatively good competitive saprophytes. The second, typified by species forming constricting rings, are comparatively poor competitive saprophytes3,4. It was thought that the loss of competitive ability by members of the latter group might be correlated with a loss in nutritional versatility with respect to carbohydrates.
