چکیده

The construction of minimum enzymes cocktails could facilitate the bioconversion of specified feedstocks into monosaccharides or XOS. In recent reported researches, the hemicelluloses and recombinant hemicellulases, including endo-ß-1,4-xylanases, ß-xylosidases, α-L-arabinofuranosidases, acetyl xylan esterase, feruloyl esterase and mannanase as well as their interaction mechanisms were investigated by enzymatic hydrolysis. Four representative interesting works on exploring the synergistic mechanisms and effects between enzymes were reported in this paper. Recombinant enzymes expressed from Pichia pastoris were characterized to reveal the mechanism during the process. This study contributes to the development of efficient enzyme cocktails for the bioconversion of hemicelluloses into monosaccharides and XOS.

Efficient Keratinolysis of Poultry Feather Waste by The Halotolerant Keratinase from Salicola Marasensis

Sustainable development in the bio-treatment of large-scale biomass bulks requires high performance enzymes adapted to extreme conditions. An extracellular keratinolytic extract was obtained from the culture broth of a halotolerant strain of Salicola marasensis. Keratin hydrolyzing activity of the concentrated enzyme extract was observed on a 100 mg of pretreated feather waste...

Development of Thermophilic Tailor-Made Enzyme Mixtures for the Bioconversion of Agricultural and Forest Residues

Even though the main components of all lignocellulosic feedstocks include cellulose, hemicellulose, as well as the protective lignin matrix, there are some differences in structure, such as in hardwoods and softwoods, which may influence the degradability of the materials. Under this view, various types of biomass might require a minimal set of enzymes that has to be tailor-made. Partially defi...

Cloning, expression and purification of hemagglutinin conserved domain (HA2) of influenza A virus, to be used in broad-spectrum subunit vaccine cocktails

Introduction: Influenza virus has several conserved peptides which have the capacity to be used as suitable candidates for appropriate and stable vaccine production against different types of influenza viruses. One of these peptides is HA2, the hemagglutinin stalk domain which mediates the membrane fusion and is conserved amongst different sub-types of influenza virus. This peptide is a good ca...

Effects of residual lignin and heteropolysaccharides on the bioconversion of softwood lignocellulose nanofibrils obtained by SO2-ethanol-water fractionation.

The amount of residual lignin and hemicelluloses in softwood fibers was systematically varied by SO2-ethanol-water fractionation for integrated biorefinery with nanomaterial and biofuel production. On the basis of their low energy demand in mechanical processing, the fibers were deconstructed to lignocellulose nanofibrils (LCNF) and used as substrate for bioconversion. The effect of LCNF compos...
