摘要:
The invention relates to the use of an isolated arabinanase enzyme comprising the activities of (1-5)-α-arabinofuranosidic linkage endohydrolysis in (1-5)-α-L-arabinans (EC 3.2.1.99), and hydrolysis of (1-5)-α-arabinofuranosidic linkages at the non-reducing end of α-L-arabinans or α-L-arabinose-oligomers (EC 3.2.1.55), particularly an arabinan-degrading enzyme isolated from Arxula adeninivorans as feed additive in livestock breeding. Furthermore, the invention relates to the application of the arabinanase in the production of fruit juices or biofuels.
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 waster water sludge etc. in a biogas plant for a subsequent biogas process.

The present invention is directed to isolated microorganisms as well as strains and mutants thereof, biomasses, microbial oils, compositions, and cultures; methods of producing the microbial oils, biomasses, and mutants; and methods of using the isolated microorganisms, biomasses, and microbial oils.
摘要:
Provided are a feed composition, which can be stored for a long time and is easily produced and adjustable in components, and which can increase the body weight and reduce a feed conversion ratio of farm animals to which the feed composition is fed, and a production method for the feed composition. In the feed composition, a liquid feed additive obtained by fermenting a carbohydrate-containing carbohydrate raw material by Aspergillus is substituted for 5 to 50% on a dry matter basis of a feed raw-material.
摘要:
Present invention involves a method for preparation of a feed additive containing surfactin, which uses a high-yield mutant strain, Bacillus subtilis T, and soybeans as the substrate in semi-solid state fermentation and after drying and grinding of the fermented soybeans into soybean powder to give a feed additive containing surfactin; wherein each kilogram of the fermented soybean powder contains about 6-7 g of surfactin. The invention found feed grouper with the feed additive containing surfactin can promote its growth rate, the expression of its immune genes is higher (e.g. AMP, Mx and IFN-induced protein), and the mortality rate of virus-infected fish is significantly lower, indicating the feed containing surfactin has the effects of growth promotion, immunity enhancement and provides resistance to pathogen infection.
摘要:
The invention relates to the use of feed material comprising grain and Agaricus Blazei, comprising the Agaricus species in an amount between 10 to 50% by weight on dry matter, and the feed material having a moisture content of less than 10% (relative to dry matter), for administration to chicken for improvement of egg laying, preferably for improving shell quality and/or for extending the egg laying period. The invention further relates to a process for making the feed material, and feed for laying hens comprising the feed material.
摘要:
Provided are methods, systems and apparatuses to the energy efficient and selective extraction of biomolecules, e.g., small organic compounds, e.g., one or more C3-C9 alcohols, one or more C3-C5 carboxylic acids, and mixtures thereof, from an aqueous solution, particularly aqueous solutions containing the alcohol in dilute or low concentrations, for example, fermentation broths.
