Bioconversion of sugarcane biomass into ethanol: an overview about composition, pretreatment methods, detoxification of hydrolysates, enzymatic saccharification, and ethanol fermentation
Larissa Canilha,Anuj K. Chandel,Thais S. S. Milessi,Felipe Antonio Fernandes Antunes,Wagner Luiz da Costa Freitas,Maria das Graças de Almeida Felipe,Silvio Silvério da Silva +6 more
TL;DR: This paper aims to review the compositional profile of SB and SS, pretreatment methods of cane biomass, detoxification methods for the purification of hydrolysates, enzymatic hydrolysis, and the fermentation of released sugars for ethanol production.
Detoxification procedures of eucalyptus hemicellulose hydrolysate for xylitol production by Candida guilliermondii
M. L.M. Villarreal,Arnaldo Márcio Ramalho Prata,Maria das Graças de Almeida Felipe,J. B. Almeida e Silva +3 more
TL;DR: Different detoxification methods of eucalyptus residues hydrolysate are described to improve xylitol production by Candida guilliermondii and it was verified that low concentrations of acetic acid can have a benefical effect on xylitor productivity.
