Minimizing Ethanol Concentration In Organosolv Pretreatment For The Saccharification Of Loblolly Pine, Nelson B. Heringer
Minimizing Ethanol Concentration In Organosolv Pretreatment For The Saccharification Of Loblolly Pine, Nelson B. Heringer
Biological and Agricultural Engineering Undergraduate Honors Theses
Organic solvent pretreatment, commonly known as organosolv, is a method used to prepare biomass for enzymatic hydrolysis for the production of biofuels. This method common uses ethanol as the organic solvent. However, this creates an economic issue with the product stream, as ethanol becomes a product and input. This project sought to explore how decreasing the use of ethanol in organosolv pretreatment affected the recoverability of sugars after enzymatic hydrolysis. Loblolly pine (Pinus taeda L.) was pretreated at 170 °C for 60 minutes in 1% dilute sulfuric acid and an ethanol concentration varying from 65% to 35%. Compositional …
Modification Of Pathways With Pseudomonas For The Extraction And Subsequent Conversion Of Algae To Butanol, Danielle Frechette
Modification Of Pathways With Pseudomonas For The Extraction And Subsequent Conversion Of Algae To Butanol, Danielle Frechette
Biological and Agricultural Engineering Undergraduate Honors Theses
As the demand for alternative fuels steadily increases, algae continue to be an excellent source for the development of biofuels. While algae have exhibited substantial potential for butanol production, there are limitations when it comes to the extraction process-its inability to withdraw oils and sugars usable for fermentation from cell walls. The genes of two bacteria were combined, creating a new organism that can both extract sugars and oils from algal cell walls and create butanol, simplifying the fermentation process while increasing efficiency. Pseudomonas flourescens, an obligate aerobe, has been shown in literature to degrade these cell walls to make …
