Data from Federal University Provide New Insights into Biochemistry and Biotechnology

May 2, 2014

By a News Reporter-Staff News Editor at Health & Medicine Week -- New research on Biochemistry and Biotechnology is the subject of a report. According to news reporting out of Vicosa, Brazil, by NewsRx editors, research stated, "Enzymatic hydrolysis is an important but expensive step in the production of ethanol from biomass. Thus, the production of efficient enzymatic cocktails is of great interest for this biotechnological application."

Our news journalists obtained a quote from the research from Federal University, "The production of endoglucanase and xylanase activites from F. verticillioides were optimized in a factorial design (2(5)) followed by a CCDR design. Endoglucanase and xylanase activities increased from 2.8 to 8.0 U/mL and from 13.4 to 114 U/mL, respectively. The optimal pH and temperature were determined for endoglucanase (5.6, 80 degrees C), cellobiase (5.6, 60 degrees C), FPase (6.0, 55 degrees C) and xylanase (7.0, 50 degrees C)."

According to the news editors, the research concluded: "The optimized crude extract was applied in saccharification and fermentation of sugarcane bagasse from which 9.7 g/L of ethanol was produced at an ethanol/biomass yield of 0.19."
