چکیده
O processo de hidrólise do amido da torta de mamona por ácido e pela combinação de a-amilase, glicoamilase e pululanase foi realizado, seguindo de etapa de fermentação. A hidrólise química resultou em 27.3 g L de açúcares com 33.4% de eficiência de hidrólise. O hidrolisado obtido foi fermentado originando 11 g L de etanol (Y P/S =0.48 g g). A melhor condição de hidrólise enzimática foi (por grama de torta de mamona): 200 μL de a-amilase, a 90 oC; 200 μL de glicoamilase e 100 μL de pullulanase, ambas a 60 °C, que resultou em 75 g L de açúcares redutores totais, que corresponde a 91.4% de eficiência de hidrólise. Esses açúcares em seguida foram convertidos em 34.5 g L etanol. O processo de hidrólise ácida foi capaz de promover a destoxificação da torta de mamona.

Castor bean (Ricinus communis L.) is cultivated mainly for biodiesel production because of its oil-rich seeds; it is assumed to be an anemophylous species. But pollination deficit can lead to low productivity often attributed to other reasons. In this paper, we investigated pollination requirements, pollination mechanism, occurrence of pollination deficit, and the role of biotic pollinators in ...

The crude oil of Malaysian castor bean ricinus communis L. seed was extracted by Soxhlet method using hexane. The physicochemical characteristics of castor bean oil were evaluated. The results showed that Malaysian castor seeds contain a relatively high percentage of total lipids content; 43.3% (per dry weight), high iodine value (84.5 mg/g) and saponification value (182.96 mg/g). The seed oil ...

Ricinus communis (castor bean) seeds are used to produce an alcohol-soluble oil that is used in more than 400 industrial processes. Despite its economic importance, there has been little research on the endophytic microbiota of castor bean seeds. This microbiota is important for plant metabolic processes and may have considerable biotechnological potential, such as production of lipases and pla...
