Connecting lignin-degradation pathway with pretreatment inhibitor sensitivity of Cupriavidus necator

Frontiers in Microbiology, 2014
To produce lignocellulosic biofuels economically, the complete release of monomers from the plant cell wall components, cellulose, hemicellulose and lignin, through pretreatment and hydrolysis (both enzymatic and chemical), and the efficient utilization ...

Gallium arsenide solar cells grown at rates exceeding 300 µm h−1 by hydride vapor phase epitaxy

Nature Communications, 2019
Gallium arsenide holds record efficiency for single junction solar cells, but high production costs limit applications. Here Metaferia et al. show high quality GaAs and GaInP at rates exceeding 300 and 200 micrometers per hour by dynamic hydride vapor ...

Energy efficiency in steam using industries in Greece

International Journal of Sustainable Energy, 2020
The industry sector in Greece is responsible for one-quarter of the overall total final energy consumption accounting for 3.8 Mtoe in 2015. Since 2007, a 29% decrease is noted due to the financial crisis.

Enzymatic degradation of biopolymers in amorphous and molten states: mechanisms and applications

FEBS Open Bio, EarlyView.
This review explains how polymer morphology and thermal state shape enzymatic degradation pathways, comparing amorphous and molten biopolymer structures. By integrating structure–reactivity principles with insights from thermodynamics and enzyme engineering, it highlights mechanisms that enable efficient polymer breakdown.

Expression of an endoglucanase–cellobiohydrolase fusion protein in Saccharomyces cerevisiae, Yarrowia lipolytica, and Lipomyces starkeyi

Biotechnology for Biofuels, 2018
The low secretion levels of cellobiohydrolase I (CBHI) in yeasts are one of the key barriers preventing yeast from directly degrading and utilizing lignocellulose.

Iron incorporation both intra- and extra-cellularly improves the yield and saccharification of switchgrass (Panicum virgatum L.) biomass

Biotechnology for Biofuels, 2021
Background Pretreatments are commonly used to facilitate the deconstruction of lignocellulosic biomass to its component sugars and aromatics. Previously, we showed that iron ions can be used as co-catalysts to reduce the severity of dilute acid ...
