ADAPTATION TO FUNGICIDES OF FUNGI DAMAGING PAPER

Ancient paper which has become mouldy must be disinfected with fungicides. These compounds are not sufficiently stable and there is the danger of adaptation of fungi to them. It was found that experimentally induced adaptation of fungi to phenolic and organomercuric compounds causes them to develop increasing resistance followed by changes in mOrPhology and anatomy of colonies and hyphae. Phenyl mercuric acetate exerted the strongest influence on the morphology and anatomy of fungi.
