Summary AlthoughRhizopus stolonifer, Aspergillus niger andRhizoctonia solani could be grown on gum arabic solutions of 1–4% concentrations, yet their growth was poor presumably due to lack of sufficient nitrogen. Gum arabic was found to be a good carbon source when it replaced sucrose in Czapek-Dox medium. The sporulation ofRhizopus was not affected by the presence of gum in the medium, while that ofAspergillus was appreciably affected. The number of sporulating heads was reduced, irregularity in the shape of the head due to variation in the length of spore chains was also noticed. A new medium of pH 5.6 was found satisfactory for fungal growth and could be recommended for soil isolations. Its composition is: 4% gum arabic, 1% peptone, 0.025% sodium chloride and 0.001% ferrous sulphate.
