Scholarcy highlights

  • Dried and ground banana peel biomass after hydrothermal sterilization pretreatment was used for ethanol production using simultaneous saccharification and fermentation
  • On the basis of model graphs and numerical optimization, the validation was done in a laboratory batch fermenter with cellulase, pectinase, temperature and time of nine cellulase filter paper unit/gram cellulose, 72 international units/gram pectin, 37 °C and 15 h, respectively
  • This study demonstrated that both hydrothermal pretreatment and SSF could be successfully carried out in a single vessel, and use of optimized process parameters helped achieve significant ethanol productivity, indicating commercial potential for the process
  • To the best of our knowledge, ethanol concentration and ethanol productivity of 28.2 g/l and 2.3 g/l/h, respectively from banana peels have not been reported to date
