Abstract: A method for fermentation-production of a pentanediamine, comprising: culturing a cell expressing a lysine decarboxylase to obtain a whole cell fermentation broth comprising a pentanediamine; and extracting the pentanediamine from the whole cell fermentation broth, and striping the whole cell fermentation broth of carbon dioxide contained therein before adding a strong base. The method greatly increases a production volume of the pentanediamine.

Abstract: Pre-coated analysis substrates, and methods of making the substrates and using them to analyze animal tissue, are described. The pre-coated analysis substrates can be made by forming a matrix surface on an analysis substrate; adding a protease to the matrix surface to form a pre-coated analysis substrate; and placing an animal tissue specimen on the matrix surface. The animal tissue can then be analyzed by allowing the protease to partially digest the animal tissue specimen; and analyzing the partially digested animal tissue specimen by mass spectrometry.

Abstract: The present invention provides a microorganism-derived soluble coenzyme-binding glucose dehydrogenase which catalyzes a reaction for oxidizing glucose in the presence of an electron acceptor, has an activity to maltose as low as 5% or less, and is inhibited by 1,10-phenanthroline. The invention also provides a method for producing the coenzyme-binding glucose dehydrogenase, and a method and a reagent for measuring employing the coenzyme-binding glucose dehydrogenase. According to the invention, the coenzyme-binding glucose dehydrogenase can be applied to an industrial field, and a use becomes possible also in a material production or analysis including a method for measuring or eliminating glucose in a sample using the coenzyme-binding glucose dehydrogenase as well as a method for producing an organic compound. It became also possible to provide a glucose sensor capable of accurately measuring a blood sugar level.

In another aspect, provided herein are genetically modified microorganisms that produce non-catabolic compounds more stably when serially cultured in the presence of maltose followed by the reduction or absence of maltose, and methods of producing non-catabolic compounds by culturing the genetically modified microbes under such culture conditions.
Abstract: Methods for enzyme-enhanced CO2 capture include contacting a CO2-containing gas with an aqueous absorption solution at process conditions—such as high temperature, high pH, and/or using carbonate-based solutions—in the presence of Thermovibrio ammonificans carbonic anhydrase (TACA) or functional derivative thereof for catalyzing the hydration reaction of CO2 into bicarbonate and hydrogen ions and/or catalyzing the desorption reaction to produce a CO2 gas. The TACA may be provided to flow with the solution to cycle through a CO2 capture system that includes an absorber and a stripper.
