  • Method for manufacturing a fat-soluble bioactive substance
    Patent number: 9006493
    Abstract: Provided is a production method of a lipophilic bioactive substance, which includes mixing an aqueous suspension of a microbial cell containing the lipophilic bioactive substance or a microbial cell homogenate thereof and an organic solvent in the presence of a particular surfactant, and extracting the lipophilic bioactive substance into the organic solvent phase. This production method enables extraction without using special dehydrating, drying facility, and without causing a decrease in the yield due to degraded separability between solvent and fungus body component, as well as efficient industrial production.
    Type: Grant
    Filed: July 22, 2011
    Date of Patent: April 14, 2015
    Assignee: Kaneka Corporation
    Inventors: Kento Kanaya, Yasuyuki Suzuki, Akihisa Kanda, Kazuya Yokoe
