Cultivation of lipid-producing bacteria with lignocellulosic biomass: effects of inhibitory compounds of lignocellulosic hydrolysates.
Lignocellulosic biomass has been recognized as a promising feedstock for the fermentative production of biofuel. However, the pretreatment of lignocellulose generates a number of by-products, such as furfural, 5-hydroxylmethyl furfural (5-HMF), vanillin, vanillic acids and trans-p-coumaric acid (TPCA), which are known to inhibit microbial growth. This research explores the ability of Rhodococcu...
متن کاملIdentifying inhibitory compounds in lignocellulosic biomass hydrolysates using an exometabolomics approach
BACKGROUND Inhibitors are formed that reduce the fermentation performance of fermenting yeast during the pretreatment process of lignocellulosic biomass. An exometabolomics approach was applied to systematically identify inhibitors in lignocellulosic biomass hydrolysates. RESULTS We studied the composition and fermentability of 24 different biomass hydrolysates. To create diversity, the 24 hy...
متن کاملControl of fermentation of lignocellulosic hydrolysates
In this work substrate feeding rate to a fermentation of lignocellulose hydrolysate for production of ethanol has been studied. During hydrolysis of lignocellulose inhibitors are formed that effect the microorganism (here Saccharomyces cerevisiae) that ferments the sugar to ethanol in a negative way. To make the hydrolysate fermentable the inhibitors are often removed by detoxification prior to...
متن کاملThe prospects of cellulase-producing bacteria for the bioconversion of lignocellulosic biomass
Lignocellulosic biomass is a renewable and abundant resource with great potential for bioconversion to value-added bioproducts. However, the biorefining process remains economically unfeasible due to a lack of biocatalysts that can overcome costly hurdles such as cooling from high temperature, pumping of oxygen/stirring, and, neutralization from acidic or basic pH. The extreme environmental res...
متن کاملHydrolysates of lignocellulosic materials for biohydrogen production
Lignocellulosic materials are commonly used in bio-H2 production for the sustainable energy resource development as they are abundant, cheap, renewable and highly biodegradable. In the process of the bio-H2 production, the pretreated lignocellulosic materials are firstly converted to monosaccharides by enzymolysis and then to H2 by fermentation. Since the structures of lignocellulosic materials...
