An overview of pretreatment of sugarcane bagasse for bio-ethanol production

Lignocellulosic biomasses are readily available source of renewable fuels. Since its nature as non-foodbased resource makes it more sustainable and affordable. The inherent resistance also makes it more impractical use for bio-conversion to biofuel generation. The lignocellulosic biomass’ resistance is a significant hurdle in increasing the production of biofuels. Preparing the substrates for the subsequent procedure requires a pretreatment step. These pretreatments are of various types such as physical, chemical, physio-chemical and biological. All these methods have advantages and some disadvantages. The nature and source of lignocellulosic biomass and pretreatment method employed: both factors are responsible for efficient conversion of biomass to fermentable sugar. In this review article, readers will be acquainted with the underlying knowledge essential to identify a promising pretreatment method according to the nature of biomass.
