Abstract:
... A cost-efficient system was developed for the production of single cell oil from lignocellulosic biomass. The pretreatment of corn stover by ammonium carbonate-steam explosion was performed. A maximum lignin removal rate of 47.26% was observed and confirmed by SEM, XRD and FTIR. In the process of enzymatic hydrolysis, higher initial enzyme loadings were used to reduce the reaction time to 24 h. Un ...

Abstract:
... Lignocellulosic biomass, such as corn stover, pulp and paper mill waste, and switchgrass, is a readily available feedstock for the production of monomeric sugars and platform chemicals that can then be transformed into valuable organic molecules. However, efficiently fractionating lignocellulosic biomass is difficult due to the recalcitrance of lignin at mild reaction conditions and the reactive s ...

Abstract:
... Effects of an algal hydrolyzate on the enzymatic hydrolysis of lignocelluloses were examined using four bioenergy feedstocks (poplar, corn stover, switchgrass, and anaerobically digested manure fiber). Feedstocks were pretreated using dilute acid or alkali prior to hydrolysis. Hydrolysis reactions were conducted using the neutralized algal hydrolyzate, citrate buffer, or deioinized water as reacti ...

Abstract:
... Pretreatment was the essential step for industrial application of lignocellulosic biomass. Combination of steam explosion and fungal treatment was conducted, and synergistic mechanism of the combined pretreatment was evaluated in terms of pore size distribution, crystallinity index, chemical compositions and enzymatic hydrolysis. The results showed that steam explosion destroyed the rigid structur ...

Abstract:
... A novel dynamic microwave-assisted alkali pretreatment (DMAP) of cornstalk (CS) was developed in a microwave pretreatment system, which resulted in the effective removal of lignin and an increased release of soluble compounds more accessible to microorganisms. The key factors affecting the pretreatment process were optimized for enhancing thermophilic hydrogen production by co-culture of Clostridi ...
