    Abstract: PROBLEM TO BE SOLVED: To obtain a new nitrilase having ammonia resistance, and useful for production of 2-hydroxy-4-methylthiobutylic acid(HMBA) useful as an additive to a feed. SOLUTION: This new nitrilase is derived from Rhodococcus rhodochrous, and has the following physicochemical properties: action: catalyzing the reaction for hydrolyzing a nitrile group to form a carboxylic acid group and ammonia; molecular weight: 40 kDa (by electrophoresis), or 400 kDa (by gel filtration); substrate specificity: acting on aliphatic, aromatic and heterocyclic nitriles; temperature stability: when treated at pH 6.5 for 15 min, being stable up to 40 deg.C, containing about 40% discernible deactivation at 50 deg.C, and being completely deactivated at 60 deg.C or higher; optimum temperature: about 50 deg.C; stabilizer: 1 mM dithiothreitol or 1 mM mercaptoethanol; inhibitor: deactivated with Hg++, Cu++ or the like; ammonia resistance: not inhibited by 1.5 M ammonium sulfate. Further, the HMBA can be obtained by allowing Rhodococcus rhodochrous B24-1 (FERM P-17515) to act on 2-hydroxy-4-methylthiobutylonitrile.

    Abstract: PROBLEM TO BE SOLVED: To provide a method for producing an adamantane polyol by a regioselective hydroxylation reaction of adamantanol and/or adamantane diol using a microorganism.
    SOLUTION: Search is intensively carried out on the microorganism for regioselectively hydroxylating the adamantanol and/or the adamantane diol. As a result, a high regioselective hydroxylating activity for the adamantanol and/or the adamantane diol is found out in the genus Streptomyces and the genus Kitasatospora in which the activity is conventionally unknown. Thus, the method for producing the adamantane polyol using the microorganism is completed. That is, the method for producing the adamantane polyol comprising a step of reacting the adamantanol and/or the adamantane diol with the microorganism belonging to the genus Streptomyces or a treated substance thereof or the microorganism belonging to the genus Kitasatospora or a treated substance thereof is provided.

    Abstract: PROBLEM TO BE SOLVED: To obtain a new microorganism as a kind of microorganisms containing 16S rRNA gene having specific base sequences, having the ability to convert a nitrile to the corresponding amide in high production efficiency, and useful in e.g. producing an amide compound for producing feed additives, or the like. SOLUTION: The new kind of microorganism is e.g. Rhodococcus sp.Cr4 strain (FERM BP-6596), containing 16S rRNA gene having respective base sequences of formula I and formula II and having the ability to convert a nitrile to the corresponding amide, thus being useful in producing the corresponding amide compound from a nitrile such as a cyanohydrin of formula III (R1 is a hydrocarbon group or heterocyclic group optionally having substituent(s)). The Rhodococcus sp.Cr4 strain as the new kind of microorganisms has been afforded by isolation using an accumulation method by culture in a selective medium from the soil collected from a certain field soil in Okayama City, Okayama Prefecture, Japan.

    Abstract: PROBLEM TO BE SOLVED: To provide a nitrilase-producing microorganism having high resistance to organic solvents, and to provide a method for efficiently producing a carboxylic acid from a nitrile, by utilizing nitrilase activity of the microorganism. SOLUTION: In this method for producing the carboxylic acid, the microorganism, which belongs to the genus Arthrobacter, in which 10% or more of the nitrilase activity is left in case of being treated at 20°C for 60 min in the presence of a 40%-organic solvent, and which concretely comprises a substance having the nitrilase activity comprising an Arthrobacter SP F-73 strain and/or its treated product, is brought into contact with the nitrile in a reaction liquid which is formed by adding an organic solvent to an aqueous reaction liquid, and then the carboxylic acid which is formed by hydrolyzing the nitrile is recovered.
