title: Polar vineyard pruning extracts increase the activity of the main ligninolytic enzymes in Lentinula edodes cultures.
abstract: Lentinula edodes is considered an alternative recycling agent for agricultural wastes, and there have been several studies to understand the relationship between its growth and ligninolytic activity. We tested the effect of wood from viticulture pruning, extracted with solvents of differing polarity, on the biomass production and activity pattern of ligninolytic enzymes. The analysis was done by measuring the mycelial dry mass and enzyme activity of liquid growth medium during the culture of L. edodes, adding either single extracts or a combination of extracts. Polar extracts enhanced mycelial production, and the activity patterns of lignin peroxidase, manganese peroxidase, aryl alcohol oxidase, and laccase were comparable to their activities predicted by ligninolysis models proposed for other fungi. We conclude that the polar extracts could be useful for enhancing fungal biomass production and for modifying lignin degradation because the regulation of ligninolytic enzyme activity is differentially influenced by the polarity of the extract.
