| Abstract | This study aimed to characterise and select among bagasse from different sugarcane cultivars developed for reduced pre-treatment requirements and maximised biomass yields. The first selection process was based on the carbohydrate composition and pretreatment response to dilute acid at low severity conditions. Out of 115 sugarcane cultivars that were characterised, 34 cultivars were shortlisted as best candidates. In the second stage, 34 cultivars were pretreated under five different conditions. The results showed that, at the same pretreatment combined severity factor, a 1.5-fold in total sugars yield increase was observed among the cultivars from their lowest value. This work is in progress to identify best 6 cultivars, which could release fermentable sugars at low pretreatment severity and low enzyme loading. After the selection of the best 6 cultivars, series of experiments will be conducted on them to optimize the pretreatment conditions using suitable statistical approach. It is expected, based on this approach, that optimal pretreatment conditions leading to low production costs of bioethanol from sugar cultivars will be obtained. Thereafter, fermentation studies will then be conducted using xylose fermenting yeast. |
