(Universidade Federal de São Carlos, 2015-03-31)
The mesenchymal stromal cells (CEMs), considered a promising alternative due to the
characteristics of self-regeneration and differentiation potential, occur in small amounts
in different tissues of an adult individual. ...
Assesment of alternative routes for sugarcane-based ethanol recovery: exergy and economic analysis
(Universidade Federal de São Carlos, 2018-02-28)
The aim of this thesis was to develop a methodological approach that can systematically guide process simulation for better understanding of bioethanol production process. In the present work, the ethanol production process ...
Estudo da produção de bioetanol e biobutanol a partir da palha de cana-de-açúcar
(Universidade Federal de São Carlos, 2019-02-18)
The present thesis studied the hydrolysis and fermentation steps of the hydrothermally pretreated sugarcane straw (cellulosic fraction), aiming bioethanol and biobutanol production. In regards to the hydrolysis step, it ...
Avaliação de adsorventes obtidos a partir de resíduos agroindustriais para a remoção dos inibidores gerados no pré-tratamento da biomassa lignocelulósica
(Universidade Federal de São Carlos, 2019-02-26)
The pretreatment of lignocellulosic biomass generates phenolic compounds and furaldehydes that inhibit the enzymes and yeast used in the process of hydrolysis of cellulose and alcoholic fermentation. In this context, the ...
