PRODUCTION OF XYLO-OLIGOSACCHARIDES FROM MISCANTHUS x GIGANTEUS BY AUTOHYDROLYSIS
Xylo-oligosaccharides were obtained from Miscanthus x giganteus. The process was designed as a biorefinery scheme, which seeks the separation of the three main components: cellulose, hemicelluloses, and lignin. To extract the hemicelluloses, particularly xylans, in an efficient way, Miscanthus was subjected to autohydrolysis. The system was evaluated for the effects of temperature (160 to 200oC...
متن کاملThe Effects of Land-Use Change from Grassland to Miscanthus x giganteus on Soil N2O Emissions
A one year field trial was carried out on three adjacent unfertilised plots; an 18 year old grassland, a 14 year old established Miscanthus crop, and a 7 month old newly planted Miscanthus crop. Measurements of N2O, soil temperature, water filled pore space (WFPS), and inorganic nitrogen concentrations, were made every one to two weeks. Soil temperature, WFPS and NO3 and NH4 concentrations were...
متن کاملImpact of diffuse nitrate pollution sources on groundwater quality--some examples from Czechoslovakia.
In several regions of Czechoslovakia with intensive agricultural production, the correlation between the amount of nitrogen fertilizer applied and the nitrate content in groundwater has been recognized. Nitrate pollution of groundwater is considered to be the most serious source of nonpoint pollution in Czechoslovakia. A program of research into the effects of farming activities on groundwater ...
متن کاملDevelopment and feeding of fall armyworm on Miscanthus x giganteus and switchgrass.
Observations of fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), larvae infesting plots of Miscanthus x giganteus Greef and Deuter ex Hodkinson and Renvoize prompted laboratory-based tests of survival, development, and feeding preferences on leaf tissue from M. x giganteus and switchgrass, Panicum virgatum L. Survival from hatch to pupation was >70 and 50% for fall ar...
متن کاملEnvironmental hazards related to Miscanthus x giganteus cultivation on heavy metal contaminated soil
According to recent estimates reaching the target of a 20% share of renewable energy sources (RES) in the final energy balance in Poland by 2020 will result in the demand for more than 8 million tons of biomass, which, in turn, will entail the necessity of creating large-scale energy crop plantations. According to EU assumptions the most effective way to produce biomass for energy purposes is c...
