Abstract: A process for the preparation of a monovalent succinate salt includes: a) fermenting a carbohydrate source to succinic acid by means of a micro-organism, b) adding a alkaline earth metal hydroxide, carbonate and/or hydrogencarbonate, the alkaline earth metal being calcium or magnesium, as neutralising agent during the fermentation in an aqueous medium and causing the formation of calcium succinate or magnesium succinate, c) reacting the alkaline earth metal succinate salt in an aqueous medium with a monovalent hydroxide, carbonate and/or hydrogencarbonate base to form an alkaline earth metal hydroxide, carbonate and/or hydrogencarbonate and a monovalent succinate salt, d) separating the monovalent succinate salt from the alkaline earth metal hydroxide, carbonate and/or hydrogencarbonate, and e) recycling the alkaline earth metal hydroxide, carbonate and/or hydrogencarbonate to step b.
Abstract: The invention describes novel pharmaceutical compositions for the treatment of virus infections and cancer. The pharmaceutical compositions include mutant oligoadenylate synthetases (OAS) that have either enhanced cell permeability, reduced oxidative potential, improved antiviral activity, improved enzymatic activity, or absent enzymatic activity. The pharmaceutical compositions have improved drug properties and retain or have enhanced antiviral activity relative to their native forms. The pharmaceutical compositions further include chemically modified oligoadenylate synthetases, such chemical modifications being designed to increase serum stability and reduce immunogenicity in vivo. Such chemical modifications further increase drug stability and manufacturability in vitro. Compositions composed of more than ninety novel modifications are described. Also described are antibodies to polypeptides of the invention.

Abstract: The bacteriolytic effect of a bacterial cell wall lytic enzyme can be increased by the addition of a surfactant to the enzyme. As a result, the time required for lysis of cariogenic bacterium with the bacterial cell wall lytic enzyme can be shortened, and the practical utility of the bacterial cell wall lytic enzyme (such as automutanolysin) as a prophylactic or therapeutic agent for dental caries can be improved.
Abstract: In a step of contacting an organic material including formic acid ions and a carbon source other than the formic acid ions with a microorganism having a formate dehydrogenase gene and a hydrogenase gene under an anaerobic condition, concentration of the formic acid ions in the organic material is set to be not less than 0.01 mol/L and not more than 0.5 mol/L, and concentration of the carbon source is set to not less than 0.1 mmol/L and not more than 200 mmol/L. This allows continuously producing hydrogen for a long time, without dropping the ability of the microorganism to produce hydrogen.

Abstract: Methods for the fermentive production of four carbon alcohols are provided. Specifically, butanol, preferably 2-butanol is produced by the fermentive growth of a recombinant bacteria expressing a 2-butanol biosynthetic pathway. The recombinant microorganisms and methods of the invention can also be adapted to produce 2-butanone, an intermediate in the 2-butanol biosynthetic pathways disclosed herein. Specifically disclosed herein are the use of coenzyme B12-independent butanediol dehydratases that catalyzes the substrate to product conversion of 2,3-butanediol to 2-butanone in the process of producing 2-butanol and 2-butanone.
