Sažetak

Solid-state fermentation (SSF) is a process performed in the absence of free water on non- soluble materials which can act as physical support and source of nutrients to microorganisms [1]. In this paper white rot fungus Trametes versicolor was cultivated in solid state-operating bioreactor with the inlet flow of 3 L min-1 kg-1 using sugar beet waste as a substrate. The main objective of the work was to determine the lignin- degrading capacity and TC removal capacity of the applied fungus. The initial material was comprised of 4.82 % of lignin, 43.79 % of total carbon (TC), out of which 0.01 % inorganic carbon (IC) and 43.78 % organic carbon (TOC). In comparison to lignin degradation, where 69 % of lignin was degraded, results of TOC analysis indicate TC degradation capacity 1 % of TC was removed mainly due to the lack of cellulolytic enzymes.
