摘要:
A cellulose hydrolase and a gene thereof are obtained by screening a cDNA genomic library constructed with Orpinomyces sp. Y102. The gene is 1071 base pairs long and comprises an open reading frame (ORF) for producing the cellulose hydrolase comprising 357 amino acids by translation. A transformed cell and a carrier carrying the gene are introduced. The gene is transferred to E. coli by transformation, such that E. coli can acquire activity of decomposing CMC, beta-glucan, and xylan. The cellulose hydrolase is multifunctional and is capable of decomposing cellubiose and directly decomposing fiber into glucose.

This invention discloses a monolithic inductor including a body made by compressing a magnetic powder, a coil positioned in the body, and a permanent magnet positioned in the body and in a magnetic circuit formed by applying current to the coil. The monolithic inductor of this invention includes the magnetic body containing the permanent magnet and the coil. The permanent magnet in the magnetic circuit (path of magnetic flux lines) formed by applying current to the coil generates a reverse-bias magnetic field, thereby increasing the operating range of the magnetic body, the saturation current of the magnetic body, and the rated current of the inductor.

A method for culturing the yeast for enhancing pentitol production is provided. The yeast cultured according to the present disclosure is Pichia stipitis. Application of the yeast in pentitol production by fermention of the lignocellulosic hydrolysate or the xylose-to-pentitol production yield can be enhanced 3 to 6 times from the non-detoxified or the overliming-processed lignocellulosic hydrolysate
摘要:
A method for producing xylitol by fermentation of lignocellulosic hydrolysates without detoxification is provided. By using the originally isolated yeast Candida sp., xylose can be effectively converted into xylitol. The invention also provides the Candida strain having high furfural tolerance, and is capable to produce xylitol from various types of non-detoxified lignocellulosic hydrolysates, in which the overall utilization of xylose in hydrolysate can reach over 95%.
摘要:
A wild seaweed, like sea lettuce, is picked and germ cells are released from the seaweed. The germ cells then obtain adherence and are sprouted into youngs of the seaweed so that the seaweed can be cultivated artificially and productively and can be supplied as a material for biomass energy.
摘要:
The present invention relates to a power inductor having a heat dissipating structure formed on the surface thereof, which comprises: at least a conducting wire; and a cladding, made of a magnetic material for wrapping the conductive wire, having the heat dissipating structure of embossed patterns formed on the surface thereof. Preferably, the embossed pattern can be a cone, a cuboid, a column, or the combination thereof. Moreover, the length of any edge or the diameter of any one of the embossed patterns is about 1%˜50% of that of the power inductor, and the height of any one of the embossed patterns is about 1%˜50% of the thickness of the power inductor.
摘要:
DNA encoding a plant quinolate phosphoribosyl transferase (QPRTase) enzyme, and constructs comprising such DNA are provided. Methods of altering quinolate phosphoribosyl transferase expression are provided.
摘要:
The present invention relates to a method of manufacturing an LED, comprising the steps of: first, forming a tape coppery metal strip; then, continuously pressing circuits on the tape coppery metal strip so as to form a carrier having circuit patterns of electric contacts on which the diode dies can be placed; next, electroplating a plurality of metal layers on the surface of the carrier; then, performing continuous injection molding on the carrier so as to form a protector having a designated shape; and curing and fixing the diode die on the carrier to connect to the terminal contact of the carrier via a metal wire. A conductive or non-conductive adhesive is dropped onto the bonding position between the metal wire and the terminal of the carrier, and a soft paste is further applied to cover the diode die, the metal wire and the terminal.
摘要:
The present invention discloses a new type joint assembly for plates. By using this new type joint component, it is possible to complete the riveting of the plate and the joint component during the manufacturing of the plate, detachment becomes easier, so it is convenient to maintain and disassemble the carriage body. While ensuring that the carriage body of the containers or the van trailers have relatively larger interior width, the inner and outer surfaces of the entire side panels are flat or substantially flat.
