A competitive 2G ethanol production is still a scientific and technological challenge, both in terms of biomass processing as well as in the biochemical conversion of the carbohydrate fractions. One of the major barriers of this process is the development a technological route able to efficiently recover the carbohydrate fractions taking into account the characteristics of the biomass use…
A major challenge to the viability of ethanol production from lignocellulosic materials is obtaining a cellulosic fraction with high reactivity and accessibility to hydrolytic agents, coupled with a high recovery of hemicellulose sugars. In this sense, the hydrolysis with dilute acid has been identified as a promising technology option since this method promotes an efíicient removal of mo…
The use of lignocellulosic constituents in biotechnological processes requires a selective separation of the main fractions (cellulose, hemicellulose and lignin). During diluted acid hydrolysis for hemicellulose extraction, several toxic compounds are formed by the degradation of sugars and lignin, which have ability to inhibit microbial metabolism. Thus, the use of a detoxification step …

Rice straw is composed mostly of polysaccharides (approximately 70%) with glucose being the main sugar of the cellulosic fraction and xylose of the hemicellulosic fraction. These sugars can be fermented by specific microorganisms, such as Candida guilliermondii, to obtain important products within a biorefinery context, such as ethanol and xylitol. For the production of these bioproducts …
One of the greatest challenges facing society in the 21st century is to reconcile the growing energy demand for industrial and transport needs with sustainability. The ethanol fuel, which can be obtained from different raw materials by biotechnological processes, has been considered as a possible alternative to petroleum based fuels. Among the materials that can be used for ethanol produc…
This project aims at optimizing and scaling up of treatment for detoxification of rice straw hemicellulosic hydrolysate by advanced oxidative processes (AOPs), to its use as a culture medium for ethanol production by yeast Pichia stipitis NRRL Y- 7124. In the first stage a 23 factorial design will be used to evaluate the influence of the concentration of O3, H2O2 and initial pH on the red…

The present project aims to perform a techno-economic evaluation of the second-generation ethanol production from rice straw, within the biorefinery concept. These studies will be performed taking into account the conditions already defined in the current PhD project, which consists in applying a mild alkaline pretreatment before the dilute acid pretreatment step, followed by enzymatic hy…
