Transformation of Quercus petraea litter: successive changes in litter chemistry are reflected in differential enzyme activity and changes in the microbial community composition

Popis výsledku v původním jazyce

Three phases of decomposition were distinguished during the decomposition of Quercus petraea litter in situ. In the early 4-month stage with high activities of ?-glucosidase, ?-xylosidase and cellobiohydrolase, 16% of litter was decomposed. Hemicelluloses were rapidly removed while cellulose and lignin degradation was slow. In months 4-12 with high endocellulase and endoxylanase activities, decomposition of cellulose prevailed and 32% of litter mass were lost. After the third phase of decomposition until month 24 with high activity of ligninolytic enzymes, litter mass loss reached 68%. After two years of decay, cellulose decomposition was almost complete and most of the remaining polysaccharides were in the form of hemicelluloses. Fungi largely dominated over bacteria as leaf endophytes and also in the litter immediately before contact with soil and this fungal dominance lasted until month 4
