Journal ArticleDOI
Fermentation of lignocellulosic hydrolysates. II: inhibitors and mechanisms of inhibition.
TL;DR: In this article, the authors discuss the generation of inhibitors during degradation of lignocellulosic materials, and the effect of these on fermentation yield and productivity, and their interaction effects are reviewed.

Pretreatment: the key to unlocking low-cost cellulosic ethanol
Bin Yang,Charles E. Wyman +1 more
TL;DR: A number of different pretreatments involving biological, chemical, physical, and thermal approaches have been investigated over the years, but only those that employ chemicals currently offer the high yields and low costs vital to economic success.

Pretreatment of lignocellulose: Formation of inhibitory by-products and strategies for minimizing their effects
Leif J. Jönsson,Carlos Martín +1 more
TL;DR: The importance of management of inhibition problems is envisaged to increase as issues that become increasingly relevant will include the possibility to use recalcitrant feedstocks, obtaining high product yields and high productivity, minimizing the charges of enzymes and microorganisms, and using high solids loadings to obtain high product titers.
Journal ArticleDOI
Inhibition of ethanol-producing yeast and bacteria by degradation products produced during pre-treatment of biomass.
TL;DR: The inhibitory effect on ethanol production by yeast and bacteria is presented and the inhibition of volumetric ethanol productivity was found to depend on the amount of methoxyl substituents and hence hydrophobicity (log P).
Journal ArticleDOI
Fermentation of lignocellulosic hydrolysates. I: inhibition and detoxification
TL;DR: In this article, the effect of various detoxification methods on the fermentability and chemical composition of lignocellulosic hydrolysates is discussed. But, the main focus of this paper is on the effects of different batch, fed-batch, and continuous fermentation strategies in relation to inhibition of fermentation.
