Abstract
Abstract
The effect of lignocellulose and lignin on growth of mycelium of mushroom Lentinula edodes and laccase activity in cultivation medium was studied. It was shown that cultivation of L. edodes mycelium in liquid nutrient medium with addition of 0.25-0.5% of kraft lignin increased mycelium biomass yield approximately two times compared with reference conditions without addition of lignin. Similar results were obtained in experiments in which 0.5% lignocellulose that remained after obtaining furfural, and 0.5% lignin that remained after obtaining furfural and glucose from wheat straw, were added to the nutrient medium. This effect was greater in the conditions of cultivation with good aeration, compared with static culture. Laccase activity in medium increased after addition of wheat straw lignocellulose or lignin only in the case of mycelium cultivation with aeration. In the case of mushroom cultivation on solid nutrient medium, addition of wheat straw lignocellulose and lignin promoted growth of mycelium only during the first 7 days of cultivation.
