New Bioresource Technology Study Findings Have Been Reported by Investigators at CIEMAT

May 27, 2014



By a News Reporter-Staff News Editor at Life Science Weekly -- Current study results on Bioresource Technology have been published. According to news originating from Madrid, Spain, by NewsRx correspondents, research stated, "A pretreatment that combines a thermo-mechanical process (extrusion) with chemical and biological catalysts to produce fermentable sugars from barley straw (BS) biomass was investigated. BS was firstly extruded with alkali and then, the pretreated material (extrudate) was submitted to extrusion with hydrolytic enzymes (bioextrusion)."

Our news journalists obtained a quote from the research from CIEMAT, "The bioextrudate was found to have 35% (w/w dwb) of total solids in soluble form, partly coming from carbohydrate hydrolysis during bioextrusion. About 48% of soluble solids dry weight is comprised by sugars, mostly glucose and xylose. Further enzymatic hydrolysis of bioextrudate could be successfully carried out at high solid loading level of 30% (w/v), with sugar production yield of 32 g glucose and 18 g xylose/100 g bioextrudate at 72 h incubation (equivalent to 96 and 52 g/l concentration, respectively)."

According to the news editors, the research concluded: "These results, together with the high level of integration of the process, indicate a great potential of this pretreatment technology for sugar production from lignocellulosic substrates."
