Butanol production from lignocellulosic biomass: revisiting fermentation performance indicators with exploratory data analysis
Birgen, Cansu; Dürre, Peter; Preisig, Heinz A.; Wentzel, Alexander (Journal article; Peer reviewed, 2019)After just more than 100 years of history of industrial acetone–butanol–ethanol (ABE) fermentation, patented by Weizmann in the UK in 1915, butanol is again today considered a promising biofuel alternative based on several ... -
Butanol production from lignocellulosic sugars by Clostridium beijerinckii in microbioreactors
Birgen, Cansu; Degnes, Kristin Fløgstad; Markussen, Sidsel; Wentzel, Alexander; Sletta, Håvard (Peer reviewed; Journal article, 2021)Butanol (n-butanol) has been gaining attention as a renewable energy carrier and an alternative biofuel with superior properties to the most widely used ethanol. We performed 48 anaerobic fermentations simultaneously with ... -
Efficacy of a novel sequential enzymatic hydrolysis of lignocellulosic biomass and inhibition characteristics of monosugars
Baksi, Sibashish; Ball, Akash K.; Sarkar, Ujjaini; Banerjee, Debopam; Wentzel, Alexander; Preisig, Heinz A.; Kuniyal, Jagdish Chandra; Birgen, Cansu; Saha, Sudeshna; Wittgens, Bernd; Markussen, Sidsel (Peer reviewed; Journal article, 2019)Efficient production of sugar monomers from lignocellulose is often hampered by serious bottle-necks in biomass hydrolysis. The present study reveals that ultra-sonication assisted pretreatment following autoclaving, termed ... -
Kinetic Study of Butanol Production from Mixtures of Glucose and Xylose and Investigation of Different Pre-growth Strategies
Birgen, Cansu; Berglihn, Olaf Trygve; Preisig, Heinz A.; Wentzel, Alexander (Journal article; Peer reviewed, 2019)This study proposes a dynamic model that describes key characteristics of fermentative butanol production from glucose and xylose mixtures. The model has 12 parameters and incorporates noncompetitive inhibitory interaction ... -
Operational guidelines for emissions control using cross-correlation analysis of waste-to-energy process data
Birgen, Cansu; Magnanelli, Elisa; Carlsson, Per; Becidan, Michael (Peer reviewed; Journal article, 2021)The aim of this study was to develop a data analysis method which could provide operational insights and guidelines waste-to-energy (WtE) plant operators. A method to filter outliers with changing properties was combined ... -
Studies on delignification and inhibitory enzyme kinetics of alkaline peroxide pre-treated pine and deodar saw dust
Baksi, Sibashish; Sarkar, Ujjaini; Saha, Sudeshna; Ball, Akash K.; Kuniyal, Jagdish Chandra; Wentzel, Alexander; Birgen, Cansu; Preisig, Heinz A.; Wittgens, Bernd; Markussen, Sidsel (Peer reviewed; Journal article, 2019)Delignification of lignocellulosic biomass by alkaline peroxide pre-treatment is a preliminary important step for an overall biomass fractionation process. In the present work, saw dusts are pre-treated by aqueous alkaline ...
