Abstract: | Summary Certain volatile organic acids stimulated the growth of Stereum sanguinolentum when added through the gas phase or to the liquid nutrient medium. Some of the acids were identified in extract of heat-treated wood of pine (Pinus silvestris), which had been shown (Suolahti, 1951) to have a growth-promoting effect on Stereum sanguinolentum and other wood-rotting fungi.The effect of volatile materials from a heat-treated piece of pine-wood and of caproic acid was tested on 13 other wood-rotting fungi. The growth of 11 of them was stimulated by volatiles from pine-wood, only 2 by caproic acid.The morphology of Coniophora cerebella was altered when volatiles from a neutral fraction of pine-wood extract was added through the gas phase. |
