ABSTRACT

Polysaccharides (PSs) were extracted from the biomass of the turkey tail medicinal mushroom, Trametes versicolor, cultivated on a corn straw substrate using a horizontal stirred tank reactor with a 0.065 mass ratio of PS (w/w dry biomass). Equilibrium and mass balance were obtained from laboratory experiments. From a single-stage extraction of PSs with the mass ratio of boiling water 10:1 (w/w dry biomass), it was found that only 35% of all PSs could be recovered (extraction efficiency) and that 10-minute extraction was sufficient to obtain more than 90% of the equilibrium value. A model based on a stage-to-stage calculation and 98% extraction efficiency (ε) enabled us to compute the number of ideal stages for a counter-current leaching system. Concentration of PSs at the exit point of the 6-stage counter-current leaching cascade was 5.9 g/L and was higher than the one obtained after a single-stage extraction process (5.2 g/L).
