Thermophilic fermentation of hydrolysates: the effect of inhibitors on growth of thermophilic bacteria.
Lignocellulosic biomass has great potential as a cheap feedstock in biological processes to produce biofuels or chemicals; however, dilute acid pretreatment at high temperatures produces undesirable compounds. Toxicity tests were done with inhibitors in standard media, to predict the growth-limiting effects on thermophilic strains. The 22 inhibitors included furfural, levulinic acid, acetic acid, and cinnamaldehyde. Neutralizing reagents and additional treatment steps have been tested.
