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.

Physicochemical characterization, antioxidant activity, and sensory analysis of beers brewed with cashew peduncle (Anacardium occidentale) and orange peel (Citrus sinensis)

“…However, these activities account only about 10% of its use, because much of it is wasted in the field and when its chestnut is removed for the chestnut industry (Prommajak et al, 2014). Moreover, its nutritional composition containing vitamin C, phenolic compounds, flavonoids, tannins, minerals, and fermentable sugars, which favor its use as an adjunct ingredient in fermented beverages (Figueiredo et al, 2002;Medeiros et al, 2017).…”

Mitigation of cashew apple fruits astringency

“…This study proved the efficiency of cashew apple juice as a healthy probiotic beverage. Medeiros et al ( 2017 ) utilized cashew apple bagasse for a large-scale fermentation with Candida guilliermondii CCT-3544, to produce ethanol and xylitol. The maximum production of both of these products was found to be after 48 h of fermentation.…”

“…desempenha um papel muito importante no setor industrial, por comprovadamente, agregar valor econômico e sustentável ao setor agroindustrial do Brasil (AMBARDINI, 2016). Citando algumas aplicações deste vegetal: i) o bagaço do caju é uma importante matéria prima para aplicação energética do biogás, para produção de etanol ( SILVA et al, 2018b;MEDEIROS et al, 2017);…”
