摘要:
A recombinant microorganism having improved productivity for a protein or a polypeptide, and a method for producing a protein or a polypeptide using the recombinant microorganism, are provided.A recombinant microorganism obtained by transfecting a gene for encoding a desired protein or polypeptide into a microorganism strain which is obtained by genetically constructing to overexpress secY gene of Bacillus subtilis or a gene corresponding to the secY gene, and deleting or inactivating one or more genes selected from sporulation-associated genes and genes corresponding to the sporulation-associated genes from the genome.
摘要:
The object of the invention is to provide a microorganism which enhances productivity of cellulase and is useful for industrial production of cellulase, and to provide a method for producing cellulase by use of the microorganism. The present invention provides a recombinant microorganism produced by transferring a gene encoding cellulase to a parental microorganism which has been genetically modified so as to overexpress a Bacillus subtilis secY gene or a gene corresponding thereto.

摘要:
An electronic converter circuit system and a control method are disclosed. The electronic converter circuit system has a digital control platform, centered on a digital control chip, consisting of a hardware circuit and software, and built in with single-end, push-pull, half-bridge, full-bridge type control modes. By simple setting, the circuit system works in corresponding modes. The electronic converter circuit system mainly controls the field-effect tubes and IGBT. Control orders in the control process are output after comprehensive diagnosis of the modules by the software control platform. During conversion, the circuit works stably and has high conversion efficiency. Besides, in the control process of the electronic converter circuit system, the environmental parameters such as the temperature, humidity, altitude and intensity of the electromagnetic field of the working environment of the circuit system are tested, and various environmental factors are balanced to ensure that the whole circuit system works safely.
