  • METHOD FOR PRODUCING AMINOBENZOIC ACID OR AN AMINOBENZOIC ACID DERIVATIVE PRODUCT
    Publication number: 20210222215
    Abstract: The invention relates to a method for producing aminobenzoic acid or an aminobenzoic acid derivative using a fermentation process, in which (I) the aminobenzoic acid formed in the fermentation broth obtained by the fermentation is bound in part, or as much as possible based on the solubility equilibrium, as insoluble calcium-aminobenzoate, said insoluble calcium-aminobenzoate is then (II) either isolated as such or in a mixture with the microorganism used in the fermentation and transitioned into a water soluble form, while separating an insoluble calcium salt which is different from the calcium-aminobenzoate, and then (III) by introducing carbon dioxide under pressure into the aqueous solution from the precipitated calcium salt has been released, aminobenzoic acid is precipitated.

  • ENANTIONSELECTIVE ENZYMATIC SULFOXIDATION OF CHIRAL ARYLSULFIDES
    Publication number: 20200370080
    Abstract: What is described herein refers to isolated nucleic acid fragments encoding an oxygenase subunit (StyA) and a reductase subunit (StyB), wherein the polypeptide encoded for by the nucleotide sequence for the oxygenase subunit (StyA) and the nucleotide sequence for the reductase subunit (StyB) have activity towards chiral arylsulfides.
