The state of Tamaulipas is the first sorghum producer nationwide, in recent years interest in different types of this crop has increased; lignocellulosic biomass that is generated as crop residue are generally burned, causing greater contamination. The objective of this work was to obtain hydrolyzed acids from sweet sorghum straw and then evaluate...

The industrial production of xylitol is carried out with the chemical hydrogenation of D-xylose and it is a costly process. An alternative procedure is the fermentation of lignocellulosic residues with yeasts such as Debaryomyces hansenii (Zopf) Lodder and Kreger-van Rij. Therefore, the objective of this study was to evaluate the extraction of xyli...

The interest in biosurfactants for the removal of hydrophobic contaminants on contaminated soils is increasing. The objective of this study was to evaluate the decontamination process in sandy soils polluted with burned car engine oil, using a natural detergent, extracted from a residual stream from the corn milling industry named "corn steep liquo...
Article
The chemical or enzymatic hydrolysis of sugar cane bagasse, allows the obtaining of fermentable sugars used in the biotechnological production of ethanol by using commercial or native yeasts obtained from different lignocellulosic materials. The purpose of this study was to assess the production capacity of ethanol from a native yeast strain isolat...

La hidrólisis química o enzimática del bagazo de caña de azúcar permite la obtención de azúcares fermentables, utilizados en la producción biotecnológica de etanol, mediante el empleo de levaduras comerciales o autóctonas obtenidas de diferentes materiales lignocelulósicos. El objetivo de este trabajo fue valorar la capacidad de producción de etano...

... Comprobándose que el tratamiento 1 (720 ml de agua + 6 ml de ácido sulfúrico), tuvo un efecto negativo en la cantidad de azucares reductores generados, debido a la generación de furfural, ácido acético y hidroximetilfurfural. Estos compuestos son altamente nocivos ya que inhiben el crecimiento de Candida intermedia, siendo necesario la realización de procesos de detoxificación empleando hidróxido de sodio. Sin embargo, cabe resaltar que investigaciones de Ledezma et al. (2018), sostienen que el hidróxido de sodio puede disminuir en un 72% la generación de ácido acético y furfural (González & Barbosa, 2018;Parejas, 2019;Villarreal et al., 2006). 1 Se hizo uso del Análisis de Varianza de Welch y la identificación de grupos homogéneos con Games-Howell. 2 Se hizo uso del Análisis de Varianza Unifactorial y la identificación de grupos homogéneos con post hoc de Duncan. ...
... The specific fractionation of sorghum hemicellulose to obtain xylose-rich solutions which can be further converted into added-value products can also be a good alternative for using this abundant resource [182]. Although there are not many examples in the literature regarding the utilization of sorghum pentoses for bioproducts, their conversion to xylitol was previously reported [183,184]. ...
... Also, it should be noted that ethanol is a net energy source, easily storable, with a high oxygen content (35%) and clean combustion; it is considered to have an excellent potential for application as fuel [12]. Furthermore, a renewable resource is biomass generated by photosynthetic organisms (autotrophs), which store energy in the form of sugars that can be transformed into ethanol through fermentation [13]. ...
