Abstract: A flavin-bound glucose dehydrogenase (FAD-GDH) with high substrate specificity for D-glucose. A gene encoding a mutant FAD-GDH with its N-terminal region, containing an amino acid sequence corresponding to MKITAAIITVATAFASFASA that exists in the N-terminal region, deleted from the amino acid sequence of a wild-type FAD-GDH derived from Mucor is introduced into E. coli to obtain an E. coli transformant. Subsequently, this E. coli transformant is cultured to obtain an FAD-GDH with a specific N-terminal region deleted. The transformant allows the production of a large amount of GDH in a short time as compared with the original microorganism. An FAD-GDH that is less susceptible to the effects of dissolved oxygen and allows accurate measurement of glucose even in the presence of sugar compounds other than glucose in a sample.
Abstract: This invention relates to compositions for the sustained release of biologically active polypeptides, and methods of forming and using said compositions, for the sustained release of biologically active polypeptides.

Abstract: A fermentation process includes contacting a carbohydrate source with a microorganism in an aqueous fermentation broth to form a fermentation product which is a salt or a product with a boiling point above the boiling point of water. The fermentation process is carried out at a pressure which is below atmospheric pressure and at least at the value where the reaction medium is at its boiling point at the fermentation temperature. Water is evaporated and removed from the reactor during the fermentation in an amount which is at least 20% of the volume of liquid present in the reactor at the start of the fermentation. A fermentation process at reduced pressure while removing a substantial amount of water removes a surplus of water in the system, ensures removal of reaction heat, and may lead to improved fermentation quality.

Abstract: Novel solid-phase biosensors that utilize ink jet printing of biocompatible sol-gel based inks to create sensor strips are reported herein. Biomolecules and other reagents useful in bioassays to detect, for example, pathogenic microorganisms or toxic substances, are immobilized on a substrate, which can be paper based, by layering these substances between two layers of biomolecule compatible sol gel. The sol gel precursor solutions and solutions of the assay reagents are printed from separate nozzles in a layered approach which avoids clogging of the nozzles by the pre-mature gelling of the sol gel precursor solution. In certain embodiments of the application, a capture agent is used to concentrate a compound to be detected in specific areas on the substrate to facilitate detection.
