BACKGROUND Agave, which is well known for tequila and other liquor production in Mexico, has recently gained attention because of its attractive potential to launch sustainable bioenergy feedstock solutions for semi-arid and arid lands. It was previously found that agave cell walls contain low lignin and relatively diverse non-cellulosic polysaccharides, suggesting unique recalcitrant features ...

Brassinosteroids (BRs) are essential hormones that play crucial roles in plant growth, reproduction and response to abiotic and biotic stress. In Arabidopsis, AtCYP85A2 works as a bifunctional cytochrome P450 monooxygenase to catalyse the conversion of castasterone to brassinolide, a final rate-limiting step in the BR-biosynthetic pathway. Here, we report the functional characterizations of PtC...

The wood of five European species: black poplar (Populus nigra L.), beech (Fagus sylvatica ash (Fraxinus excelsior oak (Quercus robur and Scots pine (Pinus sylvestris L.) was subjected to thermal modification in nitrogen atmosphere at 190 °C during 6 h. Native modified varnished oiled industrial conditions. Thermally (TM) characterized by a greater absorption varnish oil when applying the first...

Adsorption of cellulase on solids resulting from pretreatment of poplar wood by ammonia fiber expansion (AFEX), ammonia recycled percolation (ARP), controlled pH, dilute acid (DA), flowthrough (FT), lime, and sulfur dioxide (SO(2)) and pure Avicel glucan was measured at 4 degrees C, as were adsorption and desorption of cellulase and adsorption of beta-glucosidase for lignin left after enzymatic...

Fast-growing poplar trees from plantations are the source of inexpensive wood that is intended mainly for chemical processing in pulp and paper industry. Their potential as raw material biofuel manufacturing widely discussed well. The detailed composition this therefore an important question. Five species poplars were investigated: Populus alba, P. maximowiczii, trichocarpa, nigra, tremula. Woo...

Abstract Chestnut bur is an agro-waste material generated in the chestnut production. It a tannin-rich lignocellulosic which might be promising raw for low-formaldehyde composite particleboard production when using urea–formaldehyde (UF) as bonding adhesive. In this study, characteristics of were analyzed to assess its application value panel. Five-type particleboards manufactured from mixture ...

Wood material is the most critical indoor and outdoor building element that has not changed since ancient times. Previous studies have determined mechanical properties of tree species with low industrial importance, such as poplar wood, can be improved when they are subjected to densification process. In addition, it been in lamination process a positive effect on wood material. This study aime...
