Abstract

There are many methods to identify and recognize the molecular and behavioural differences between organisms. One of the methods for the detection and identification of unknown organisms as well as intermolecular and intramolecular structural differences is MALDI-TOF mass spectrometry. Therefore, differentiation of Fomes fomentarius decay capabilities on the chemical properties of the wood cell wall of the tree species Quercus castaneifolia, Juglans regia, and Carpinus betulus were used to determine and characterize the destructive behaviour of F. fomentarius decay by MALDI-TOF mass spectrometry. The results showed that the fungus had more signifi- cant destructive behaviour on J. regia than the other species. For this evidence, completely removal of xylan hemicellulose fragment +Na+ at peak 1227 Da and severe digestion of fragment of glucomannan hemicellulose at peak 1477–1480 Da that it seems that signs of soft-rot patterns were obtained from the decayed sample of J. regia, while these were incremental and unchanged for C. betulus and Q. castaneifolia, respectively. However, C. betulus had different peaks of atomic mass than J. regia and Q. castaneifolia wood, respectively. These results showed that this technique could be useful for separating and identifying unknown compounds of the wood cell wall attacked by fungi relying on their biological behaviour.
