  • Patent number: 7514244
    Abstract: A process for preparing lipids which contain docosahexaenoic acid (DHA) and/or docosapentaenoic acid (DPA) is disclosed. The process includes the steps of cultivating in a medium a microorganism which belongs to the genus Ulkenia having the ability to produce DHA and/or DPA and recovering the lipids from the culture. The process may further include the step of separating DHA and/or DPA from the lipids.

  • Publication number: 20080124449
    Abstract: A food for preventing life style-related diseases of the present invention contains a mung bean protein degradation product. The mung bean protein degradation product is obtained by hydrolyzing a mung bean-derived protein with a protease. In the mung bean protein degradation product, the dipeptide or tripeptide content in the entire peptides is preferably 10% or more. The food for preventing life style-related diseases of the present invention is preferable for preventing in particular hypertension, arteriosclerosis, and obesity, for example. The present invention also provides an anti-hypertensive agent, an anti-arteriosclerotic agent, a vascular intimal hypertrophy inhibitor, and an anti-obesity agent containing the mung bean protein degradation product. Furthermore, the present invention provides a diet food containing the mung bean protein degradation product.

  • Patent number: 6582941
    Abstract: The present invention relates to the Schizochytrium genus SR21 strain and a microorganism belonging to the same species as does said SR21 strain or having substantially the same fungological properties as does said SR21 strain, the said SR21 strain and microorganism having the ability to produce the (n-3) series of docosahexaenoic acid (DHA) and the (n-6) series of docosapentaenoic acid (DPA), and the invention also relates to a process for preparing the (n-3) series of DHA and the (n-6) series of DPA utilizing said microorganisms. The microorganisms according to the present invention are superior in their proliferation character and their propensity to produce fat, and have the ability to produce the (n-3) series of DHA and the (n-6) series of DPA very well. Accordingly, it is possible to effectively produce the (n-3) series of DHA and/or the (n-6) series of DPA, which are useful in the fields of foods and pharmaceuticals, using the microorganisms according to the present invention.
