Sorghum vegetative tissues are becoming increasingly important for biofuel production. The composition of sorghum stem tissues is influenced by genotype, environment and photoperiod sensitivity, and varies widely between varieties and also between different stem tissues (outer rind vs inner pith). Here, the amount of cellulose, (1,3;1,4)-β-glucan, arabinose and xylose in the stems of twelve div...

The presence of lignin within biomass impedes the production of liquid fuels. Plants with altered lignin content and composition are more amenable to lignocellulosic conversion to ethanol and other biofuels but may be more susceptible to insect damage where lignin is an important resistance factor. However, reduced lignin lines of switchgrasses still retained insect resistance in prior studies....

Crown gall, a neoplastic disease of plants, is of interest because the inciting bacterium, Agrobacterium tumefaciens (Smith and Town.) Conn, converts normal plant cells to tumor cells in short periods of time. Once the cellular alteration has been accomplished, the continued abnormal proliferation of the affected host cells becomes completely independent of the inciting organism. These findings...

this experiment was conducted to determine the effect of procceesing of sugarcane pith with high pressure steam (210-220c◦, at 19 bar, over 3 min, on 70 % moisture) on fermentative activity and gas production parameters and degradation by pure microorganism of rumen. the microbial different groups of rumen were separated by physical and chemical methods and using antibiotics. these microbial gr...

Out-of-grade pine timber is an abundant material resource that underutilised because its mechanical properties are not well understood. Increasing trends toward shorter rotation times and fast-grown plantation pines around the world such as Pinus elliottii × P. caribaea var. hondurensis hybrid (PEE PCH) mean low-stiffness corewood becoming a larger portion of this out-of-grade population. This ...

INTRODUCTION Esca disease has become a major threat for viticulture. Phaeoacremonium aleophilum is considered a pioneer of the esca complex pathosystem, but its colonisation behaviour inside plants remains poorly investigated. MATERIAL AND METHODS In this study, P. aleophilum::gfp7 colonisation was assessed six and twelve weeks post-inoculation in two different types of tissues: in the node a...

Large scale biofuel production will be possible only if significant quantities of biomass feedstock can be stored, transported, and processed in an economic and sustainable manner. Torrefaction has the potential to significantly reduce the cost of transportation, storage, and downstream processing through the improvement of physical and chemical characteristics of biomass. The main objective of...
