Journal ArticleDOI
A review on alkaline pretreatment technology for bioconversion of lignocellulosic biomass.
TL;DR: The main features of alkaline pretreatment are that it selectively removes lignin without degrading carbohydrates, and increases porosity and surface area, thereby enhancing enzymatic hydrolysis.
Journal ArticleDOI
Pretreatment of corn stover by aqueous ammonia.
TL;DR: Corn stover was pretreated with aqueous ammonia in a flow-through column reactor, a process termed ammonia recycled percolation (ARP), and the enzymatic digestibility was related with the removal of lignin and hemicellulose, perhaps due to increased surface area and porosity.
Journal ArticleDOI
Pretreatment and fractionation of corn stover by ammonia recycle percolation process.
Tae Hyun Kim,Yoon Y. Lee +1 more
TL;DR: The X-ray crystallography data indicate that the basic crystalline structure of the cellulosic component of corn stover is not altered by the ARP treatment, and low-liquid ARP can reduce the liquid throughput and residence time to 3.3 mL/g-biomass and 10-12 min, without adversely affecting the overall effectiveness.
Journal ArticleDOI
Size-dependent cellular toxicity of silver nanoparticles.
TL;DR: The data suggest that the AgNPs-induced cytotoxic effects against tissue cells are particle size-dependent, and thus, the particle size needs careful consideration in the design of the nanoparticles for biomedical uses.
Book ChapterDOI
Pretreatment of corn stover by soaking in aqueous ammonia.
Tae Hyun Kim,Y. Y. Lee +1 more
TL;DR: When the SSCF process is used, the fact that the xylan fraction is retained during pretreatment is a desirable feature since the overall bioconversion can be carried out in a single step without separate recovery of xylose from the pretreatment liquid.
