“…The results obtained by applying the hydrothermal pretreatment were similar to those obtained for other biomass such as grape stalks, corn stalks, grass (Cynodon dactylon), sorghum, wood, olive tree prunings, eucalyptus, bamboo, wheat straw and sugarcane bagasse (Amendola et al, 2012;Egues et al, 2012;Lee et al, 2009;Rohowsky et al, 2013;Chen et al, 2010;Martin et al, 2010;Alves et al, 2010;Ruiz et al, 2013a;Ruiz et al, 2013b;Abril et al, 2012). Figure 2 shows the results of the morphological analysis of the raw material and solid fraction of the pretreated bagasse by SEM.…”

-Glucose production from sugarcane bagasse was investigated. Sugarcane bagasse was pretreated by four different methods: combined acid and alkaline, combined hydrothermal and alkaline, alkaline, and peroxide pretreatment. The raw material and the solid fraction of the pretreated bagasse were characterized according to the composition, SEM, X-ray and FTIR analysis. Glucose production after enzymatic hydrolysis of the pretreated bagasse was also evaluated. All these results were used to develop relationships between these parameters to understand better and improve this process. The results showed that the alkaline pretreatment, using sodium hydroxide, was able to reduce the amount of lignin in the sugarcane bagasse, leading to a better performance in glucose production after the pretreatment process and enzymatic hydrolysis. A good xylose production was also observed.

“…Many different pre-treatment methods have been reported, including biological, chemical, physical, thermal, and enzymatic approaches (Chandra et al 2007;Wyman 2008, Yang et al 2011;Hamzeh et al 2013;Rohowsky et al 2013). Bio-delignification is useful in the pre-treatment, and it replaces or supplements the chemical-based pre-treatments, which include mechanical treatment with acid, alkali, and steam explosion.…”

In view of the worldwide economic and environmental issues associated with the extensive use of petro-chemicals, there has been increasing research interest during the past decade in the value of residual biomass. Because of its renewable nature and abundant availability, residual biomass has attracted considerable attention as an alternate feedstock and potential energy source. To expand the range of natural bio-resources, significant progress related to the lignocellulose biotechnology has been achieved, and researchers have been re-directing their interests to biomass-based fuels, ligninolytic enzymes, chemicals, and biocompatible materials, which can be obtained from a variety of lignocellulosic waste materials. This review article focuses on the potential applications of lignocellulosic materials in biotechnology, including the production of bio-fuels, enzymes, chemicals, the pulp and paper, animal feed, and composites.

“…38,101−103 Bioethanol production was almost doubled from 21.2 g/L 103 to 53 g/L 102 due to the usage of sweet sorghum juice mixed with the pretreated and dewatered bagasse. On the other hand, SSB without any pretreatment was used to immobilize S. cerevisiae through SSF for the production of bioethanol.…”

The growth of the biobased economy will lead to an increase in new biorefinery activities. All biorefineries face the regular challenges of efficiently and economically treating their effluent to be compatible with local discharge requirements and to minimize net water consumption. The amount of wastes resulting from biorefineries industry is exponentially growing. The valorization of such wastes has drawn considerable attention with respect to resources with an observable economic and environmental concern. This has been a promising field which shows great prospective toward byproduct usage and increasing value obtained from the biorefinery. However, full-scale realization of biorefinery wastes valorization is not straightforward because several microbiological, technological and economic challenges need to be resolved. In this review we considered valorization options for cereals based biorefineries wastes while identifying their challenges and exploring the opportunities for future process.
