Bohus, G. ; Gyarmati, B.: The effects of temperature and pressure on fungi causing wood-decay

Just as ineffective was the double Rüpping method (consisting of the following working processes : air pressure — saturant pressure — vacuum — air pressure — saturant pressure — vacuum), though applied for 6 hours ; all cultures revived. Our researches on the wood-decaying fungi confirmed the findings of Chlopin, Tamann et al., on bacteria, saccharomyces and macroscopic fungi, according to which air pressure has a hardly demonstrable effect. To shortly sum up the aboves, we have to point out that researches concerning the heat tolerance of the selected wood-decaying fungi species could lend a hand to the working out of simpler methods for the liquidation of fungal infections by heat treatment ; further that the complete sterilization of Sorti­ments with a larger diameter by saturation processes can only be assured by the application of about 65° C in the whole cross-cut during at least 2,5 hours. Pressure conditions of the several saturating processes are inffective. flencTBHe TeívmepaTypbi H flaBJieHHH Ha OT^ejibHbie BHAM rpnöoB, pa3pyuiaK)iHHX ApeBecHHy r.
