Abstract Background Hydrogen peroxide–acetic acid (HPAA) is widely used in pretreatment of lignocellulose because it has a good capability selective delignification. However, high concentration (more than 60%) HPAA increases the cost and risk explosion. In this work, alkaline post-incubation was employed to decrease loading improve saccharification poplar. Results Pretreatment with 100% removed...

Elm and poplar are two tree species that can provide a large amount of low-value feedstock for biochar production due to their rapid growth rate (poplar), susceptibility disease and/or infestation (both elm poplar). Biochar has been studied recently as filtration medium water purification, it provides renewable alternative activated carbon. In this work, the adsorption efficiency biochars made ...

A Monviso clone has been applied to promote PCB degradation in a soil historically contaminated by polychlorinated biphenyls (PCBs) and heavy metals (HMs). The multi-contaminated area is located Southern Italy. PCBs, HMs, the microbial community (abundance, viability, structure) were analysed selected plots of poplar-treated area. At 900 days after poplar planting, chemical analyses showed that...

This study evaluated the potential of trees planted around commercial poultry farms to trap ammonia (NH(3)) and dust or particulate matter (PM). Norway spruce, Spike hybrid poplar, hybrid willow, and Streamco purpleosier willow were planted on five commercial farms from 2003 to 2004. Plant foliage was sampled in front of the exhaust fans and at a control distance away from the fans on one turke...

Previous research conducted in the laboratory pointed out several hardwood species which were either superior, comparable, marginal, or unsuitable for manufacturing cement-excelsior board (CEB). In this study, forty full-sized boards were manufactured in a commercial production facility with the following species: yellow-poplar, sweetgum, southern pine, and sweetgum/southem pine mixture. The pr...

Anoplophora glabripennis (Motschulsky) (Coleoptera: Cerambycidae), a pest native to China and Korea, was discovered in North America in 1996. Currently, the only reliable strategy available for eradication and control is to cut and chip all infested trees. We evaluated various doses of the systemic insecticides azadirachtin, emamectin benzoate, imidacloprid, and thiacloprid for control of A. gl...

The cambial K+ content of poplar increases during the growth period in a K+ supply dependent manner. Upon K+ starvation or application of tetraethylammoniumchloride (TEA+), a K+ channel blocker, the average vessel lumen and expansion zone area were significantly reduced. In search for the molecular basis of potassium-dependent xylogenesis in poplar, K+ transporters homologous to those of known ...

Black locust is an interesting option for biomass production at sites prone to water shortage because the species combines water-use efficiency and a yield largely superior that of poplars under conditions study. (Robinia pseudoacacia L.) tree woody production. However, its potential this purpose has been much less studied characterized than from Salicaceae family (i.e., poplar willow). The obj...

Populus tomentosa (Chinese white poplar) is well adapted to various extreme environments, and is considered an important species to study the effects of salinity stress on poplar trees. To decipher the mechanism of poplar's rapid response to short-term salinity stress, we firstly detected the changes in H2O2 and hormone, and then profiled the gene expression pattern of 10-week-old seedling root...
