Publication number: 20120164698Abstract: The invention relates to a method for preparing organic-chemical compounds, characterized in that the following steps are carried out: a) fermentation of a microorganism secreting an L-amino acid, which microorganism contains an overexpressed polynucleotide coding for a polypeptide having polyphosphate-dependent NAD+ kinase activity, in a fermentation medium, to form a fermentation broth, b) accumulation of said compound in said fermentation broth and/or in the cells of said microorganism. The invention relates to a method for preparing organic-chemical compounds by fermentation of a microorganism in which a polypeptide having polyphosphate-dependent NAD+ kinase is overexpressed.Type: ApplicationFiled: June 18, 2010Publication date: June 28, 2012Applicant: EVONIK DEGUSSA GMBHInventors: Volker F. Wendisch, Steffen Lindner, Brigitte Bathe, Wilfried Claes

Patent number: 8178322Abstract: A method is described for producing an L-amino acid or a nucleic acid by culturing a microorganism having an ability to produce the L-amino acid or nucleic acid in a liquid medium in a fermentation tank containing a stirring impeller, and optionally adding seed crystals to the medium as required to produce and accumulate crystals of the L-amino acid or nucleic acid in the medium, and collecting crystals of the L-amino acid or nucleic acid from the culture. The power density of the stirring impeller is controlled to be 2.4 kW/m3 or lower after either precipitation of the crystals or addition of the seed crystals.Type: GrantFiled: August 14, 2009Date of Patent: May 15, 2012Assignee: Ajinomoto Co., Inc.Inventors: Masayuki Araki, Yusuke Takahashi, Akihiro Watanabe, Fumito Ohnishi, Takahiro Asano, Kazuya Kondo, Wataru Hibino, Shintaro Iwatani, Satoshi Okutani
