Bioconversion of hydrolyzed cashew peduncle bagasse for ethanol and xylitol production
ABSTRACT The agro-industrial waste deposited in the environment causes problems in nature that can be solved with the use and generation of bioproducts. Thus, the objective was to study the lignocellulosic fraction of cashew (Anacardium occidentale L.) peduncle bagasse and fermentation on large scale (8-16 times) using the strain Candida guilliermondii CCT-3544 as production agent. According to the obtained results, it can be noted that the dry cashew peduncle bagasse has 21.45% of cellulose, 10.96% of hemicellulose and 35.39% of lignin. During fermentation, C. guilliermondii 3544-CAT was able to grow on medium containing hydrolysate, with maximum cell growth concentration of 3.5 g L-1. The behavior of the sugars in the fermentation process was similar in the different variables, with maximum production of ethanol and xylitol at 48 h of fermentation.
