Cellulase activity and phenol content were measured in water extracts from needles collected from Abies alba Mill. forest. Variations in cellulolytic activities in senescent needles and litter were due to the diversity of fungal colonizers and to interspecific differences in activities over the course of colonization. Phenol content was transformed quantitatively and quanlitatively in presence of fungi, therefore the biochemical environment in which cellulolytic enzymes were active had been modified.
