Wood, Tomato and Malt Extracts and Growth of Some Basidiomycetes

Abstract

SUMMARY Of 82 Basidiomycetes selected because they grew better on malt extract agar than on an agar prepared with a basal medium of mineral salts, dextrose, B vitamins, purine and pyrimidine bases and casein hydrolysate, the growth of 72 was better when the liquid basal medium was supplemented with wood, tomato or malt extract. Wood extract was the most generally beneficial. For some of the fungi 0.25 mg in dry weight of wood extract in 25 ml of culture medium caused a significant increase in growth.
