Treatment of sugar beet with Trametes versicolor with the aim of producing biofertilizer

Sugar beet pulp is a by-product of the sugar industry, obtained after the extraction of sucrose from sugar beet roots. It is usually pressed and/or dried and used as animal feed. About 13.5 million tons of sugar beet pulp are produced annually in the European Union. Chemically, it consists mainly of the polysaccharides hemicellulose (30%DM), cellulose (22-24%DM) and pectin (15-25%DM), while having lower lignin content (5.9%DM). Trametes versicolor (syn. Coriolus versicolor and Polyporus versicolor) belongs to the phylum Basidiomycota of Kingdom Fungi, colloquially called basidiomycetes. The use of this fungus has recently been intensively investigated to utilize lignocellulosic waste biomass and industrial lignocellulosic byproducts in lignocellulosic biorefineries for the production of biofuels and value-added products. In this work, sugar beet pulp was treated with Trametes versicolor under solid-state conditions for 10 days. During the treatment, pH decreased steadily (from initial 4.58 to 3.99) as well as C/N ratio, while the concentration of minerals increased. After 10 days of treatment, the C/N ratio was 22.32, indicating possible maturation of the biomass. Significant concentration of essential elements were obtained after the treatment, as follows: Ca (1.2%DM), Mg (0.38%DM), K (0.22%DM), N (0.18%DM) and P (0.1%DM). The concentrations of microelements (Fe, Mn, Zn, Cu) also increased after the treatment reaching final values as follows: Fe (535 mg kg-1), Mn (72, 8 mg kg-1), Zn (20, 9 mg kg-1), Cu (8, 9 mg kg-1). The concentrations of all tested heavy metals (Zn, Cu, Cr, Co, Ni, As, Mo, Cd, Hg, Pb) were below the maximum permissible levels. Germination tests for cucumber and watercress lettuce showed high fitotoxicity, which was also to be expected due to the low pH values.
