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 ... -
Enabling circularity: Analysis of factors influencing MSW sorting behaviour in Central Norway
Grytli, Tuva; Birgen, Cansu (Peer reviewed; Journal article, 2023)A comprehensive waste composition analysis was undertaken in 2021, covering ten municipal waste companies in Central Norway. The results are used in a multiple linear regression model to explore factors influencing the ... -
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 ... -
