KESTANE (Castanea sativa) TALAŞI PASTORİZASYON SIVISININ ODUN KORUYUCU OLARAK DEĞERLENDİRİLMESİ

In mushroom cultivation, one of the most important steps is the pasteurization or sterilization. Primarily; all raw materials such as various kinds of wood sawdust or agricultural wastes used as substrate medium are required to be pasteurized. During the process, pasteurization liquor is generally dumped without re-cycled. In this study it was investigated that the fungicidal effect of pasteurization liquor of chestnut (Castanea sativa) sawdust, which is particularly rich in tannins, against brown rot fungi “Coniophora puteana”. The wood samples were impregnated with the pasteurization solution according to the ASTM D 1413 standard test method. The protective effect of this liquor on Scotch pine (Pinus sylvestris L.) wood was considered by means of fungi decay test (EN 113). It was concluded that the pasteurization liquor enhanced the decay resistance of Scotch pine sapwood samples compared to the control group.
