The Bioconversion of Pretreated Cashew Apple Bagasse into Ethanol by SHF and SSF Processes.

Ethanol production from acidic-alkaline pretreated cashew apple bagasse (CAB-OH) was investigated using separated hydrolysis and fermentation (SHF) and simultaneous saccharification and fermentation (SSF) processes. First, a screening of Kluyveromyces strains was conducted by SHF and a maximum ethanol concentration of 24.1 g L(-1) was obtained using Kluyveromyces marxianus ATCC36907, which presented similar profiles when compared to results obtained by a Saccharomyces strain.
