Sugarcane bagasse: A promising substrate for solid-state fermentation

Uroosa Ejaz, Muhammad Sohail

Department of Microbiology, University of Karachi, Karachi, Pakistan.

Abstract

Fermentation is a process in which energy is produced as a result of incomplete oxidation of organic substrate, mostly carbohydrate, due to the microbial metabolic activities. Based on available water, fermentation is categorized as submerged fermentation and solid-State fermentation (SSF). In SSF free water is not available, and the microorganism grows on solid substrate. Due to less requirement of instrument and some other reasons, SSF is preferred for developing countries. The availability of agroindustrial waste such as sugarcane bagasse (SB) provides an additional advantage to develop SSF-based fermentation process in such countries. At present, SB is underutilized; however, being rich in fermentable constituents and less ash content, it can contend well as substrate for SSF. This review summarizes the achievements reported by utilizing SB under SSF.

Keywords: Fermentation, Pretreatment, Submerged fermentation, Sugarcane bagasse.
