Solid-state fermentation of agro-food waste: applicability comparison of two bioreactor configurations

The applicability of two laboratory-scale bioreactors for solid-state cultivation of white- rot fungus Trametes versicolor TV6 was investigated. Sugar beet pulp (SBP) was used as a non-inert carrier. Two bioreactor configurations were investigated: horizontal bioreactor (HB) and tray bioreactor (TB). SBP biodegradation was observed in both investigated bioreactors, whereas the obtained material mass loss was 21.33% and 46.50% for HB and TB, respectively. The decrease of cellulose (64.65% HB and 42.34% TB) and pentosane content (42.39% HB and 62.61% TB), as well as the ash content increase (175.5% HB and 78.9% TB), indicated good biodegradation capability of the fungus. Furthermore, the results indicate that both bioreactors could be used for biological degradation/pre-treatment of lignocellulosic materials for different biotechnological purposes using white-rot fungus T. versicolor TV6.
