The potential of sugar beet pulp (SBP) and dried sugar beet pulp (DSBP) as economically cheap and renewable supports for immobilization of Saccharomyces cerevisiae cells was investigated.
The hydrated supports showed similar cells retention capacities of 0.178 ± 0.038 g/g and 0.182 ± 0.041 g/g for SBP and DSBP, respectively.
The DSBP-immobilized biocatalyst was used for repeated ethanol fermentation, because DSBP is more stable material.
