摘要:
There is disclosed a method for processing a biomass (for example straw) containing lignocellulose such that cellulose and hemicellulose are made accessible for further processing, typically by decomposition, without needing energy-consuming dissolution of the biomass in water.The method includes repeated compressions of the biomass in a reciprocating piston press, where loose biomass is continuously fed into a piston chamber in front of a piston which moves the loose biomass into a tubular reaction chamber in which the biomass is compressed for producing a vapour explosion and autohydrolysis under simultaneous displacement of compressed biomass through the reaction chamber.After compression, the biomass can be added fluid livestock manure, fluid waste water sludge etc. in a biogas plant for a subsequent biogas process.
摘要:
By combination of hydrophobic chromatography and strongly basic anion-exchange chromatography, a novel, highly hydrophobic β-glucosidase was successfully identified from Acremonium cellulolyticus. Further, a gene corresponding to the identified β-glucosidase was isolated. When multiple modifications were introduced into the base sequence of the gene, the gene was successfully expressed in Trichoderma viride at a high level, and the expression product successfully exhibited a high β-glucosidase activity.

摘要:
A pressing or pelletizing device for compacting vegetable materials, in particular grass blades, is disclosed for use with a harvester. In order to reduce the pressing forces required for the pelletizing process, the pressing channels are heated up to a temperature above 100 degrees C. It has been demonstrated that by heating the pressing channels, local overheating of the device, which could otherwise lead to malfunctions, can be avoided. The pelletizing device has two co-axial hollow cylinders in which the pressing channels are delimited by radial lands which alternatively engage the pressing channels of the other hollow cylinder. The hollow cylinders are heated by means of a liquid circuit guided through the lands and linked to a heat exchanger that utilizes lost heat from the internal combustion engine of the harvester.
摘要:
A method, and related compositions, for reducing body fat percentage, increasing lean muscle mass and/or lowering cholesterol levels in individuals. The method consists of the ingestion of an extract derived from muira puama root, bark or other wood material. A method of preparing the muira puama extract into an easily ingestible and manipulatable solid form, and pharmaceutical compositions for use by mammalian subjects, are also disclosed.
摘要:
A feed for ruminants is produced by mixing 90-99.5% by weight of a vegetable fiber material which is indigestible by ruminants and 0.5-10% by weight of a non-protein nitrogen compound and inoculating the mixture with an effective amount of an alcoholic fermentation micro-organism, an organic acid fermentation microorganisms or an ester formation microorganisms and fermenting the inoculated mixture.
摘要:
An NPN ruminant feed supplement having a high percentage of chemically bound urea is prepared from cellulose commodities by an efficient process involving reaction with urea and a concentrated mineral acid.
