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 ... -
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 ... -

Towards a low CO2 emission building material employing bacterial metabolism (1/2): The bacterial system and prototype production
Røyne, Anja; Phua, Yi Jing; Le, Simone Balzer; Eikjeland, Ina Grosås; Josefsen, Kjell Domaas; Markussen, Sidsel; Myhr, Anders; Throne-Holst, Harald; Sikorski, Pawel; Wentzel, Alexander (Journal article; Peer reviewed, 2019)The production of concrete for construction purposes is a major source of anthropogenic CO2 emissions. One promising avenue towards a more sustainable construction industry is to make use of naturally occurring mineral-microbe ...
