Abstract: The present invention provides a method for producing a recombinant protein, which can increase the cell growth rate in culture while stably maintaining plasmids in the cells, thereby improving the recombinant protein yield. The present invention provides a method for producing a recombinant protein, including a high-temperature culture step of culturing at 32° C. or higher a Brevibacillus bacterium that contains a gene encoding a recombinant protein, and a low-temperature culture step of culturing the Brevibacillus bacterium at a temperature lower than 32° C. after the high-temperature culture step.

Abstract: A protein includes two or more amino acid sequences, wherein each amino acid sequence is derived from a sequence selected from the group consisting of SEQ ID NOs:1 to 5. The amino acid sequence closest to the N-terminus includes a substitution of an amino acid residue at a position corresponding to position 4 or 7 of SEQ ID NO: 5 with an amino acid residue other than Arg, and productivity of the protein in a transformant producing the protein is improved, as compared to productivity of a protein including the amino acid sequence without the substitution.

Abstract: Process for producing a copolyester of desired quality at low cost with high productivity, preferably a process for producing P(3HB-co-3HH) of 4 mol % or more 3HH content with a productivity as high as 40 g/L or more. In particular, a process for producing a copolyester of 3HB and 3HH comprising culturing a microorganism with the use of, as a carbon source, a fat or oil containing lauric acid as a constituent fatty acid under such conditions that phosphorus as a source of nutrition is limited.

Abstract: The object of the present invention is to develop a technology to optionally control a composition of a biodegradable copolyester with maintaining low cost and high productivity. The present invention consists in a culture method in producing a copolyester by a microorganism, which comprises controlling a specific substrate feed rate of an oil or fat to be used as a carbon source at a constant value throughout the whole culture period, or a method, which comprises applying a different specific substrate feed rate of an oil or fat used as a carbon source between a cell growth phase and a polyester accumulation phase in a culture and controlling the rate at a constant value during the respective phases. Furthermore, the present invention also consists in a culture method, which comprises controlling the composition of the produced copolyester by selecting the species and/or the control value for the specific substrate feed rate.

Abstract: An adsorbent that exhibits a high specificity in adsorbing immunoglobulins and/or complexes thereof, is extremely reduced in the lowering of the adsorption characteristic during sterilization or storage, is highly stable and safe, and is prepared by immobilizing on a water-insoluble support either a peptide derivative which has undergone at least one of the deletion, substitution, insertion, or addition of amino acids in a peptide having a specified amino acid sequence or an amino acid sequence, or the above peptide derivative which has undergone the addition of Lyn or Cys at the amino and/or carboxyl terminal thereof; a device for adsorption and removal made by packing the adsorbent in a vessel equipped with effluent preventing means; and a method of adsorbing and removing immunoglobulins and/or complexes thereof contained in the blood, plasma or other body fluids with the adsorbent.

Abstract: The present invention relates to an adsorbent being capable of efficiently adsorbing and removing interleukins in a body fluid and to a method for adsorbing and removing, if necessary, and recovering interleukins in a body fluid with the above-mentioned adsorbent. According to the present invention, there are provided an adsorbent of interleukins which comprises a water-insoluble carrier having an anionic functional group, a method for adsorbing, removing and recovering interleukins using the same and an adsorber using the same.

Abstract: The invention provides a novel method for forming a ceramic lining layer on the inward surface of a hollow body such as a pipe. According to the invention, a thermit mixture, for example, composed of aluminum powder and an iron oxide is placed in the hollow space of the hollow body, which is rotated at a high speed so as that the thermit mixture is pressed against the wall of the hollow body by the centrifugal force and the thermit mixture is ignited, for example, by contacting with an acetylene flame.
