  • Publication number: 20150010987
    Abstract: Provided is a method that is for producing Euglena having a high wax ester content, capable of more efficiently producing the Euglena having a high wax ester content by adding a nutrient before anaerobic fermentation to restore the efficiency of wax ester fermentation. The present invention relates to a method for producing Euglena having a high wax ester content. The main configuration of the method is that there is at least a first step of aerobically culturing microalga Euglena under nitrogen starvation conditions and a second step of holding the cells in an anaerobic state; and adding, before the second step, a nutrient source to the culture liquid which has passed through the first step.

  • Patent number: 5972648
    Abstract: Disclosed are hirudin analogs, a method of manufacture thereof, and anticoagulant compositions containing the same. Sequences Asp.sup.33 -Gly.sup.34 or Asp.sup.62 -Ala.sup.63 of naturally-occurring hirudins or their analogs were substituted as disclosed to suppress the formation of succinimide- or beta- forms, thereby yielding hirudin analogs with high stability, high anti-thrombin activity, and therapeutic potential as anticoagulants. Hirudin analogs having Val.sup.1 -Val.sup.2 of naturally-occurring hirudin substituted with Ile.sup.1 -Ile.sup.2 are preferred for their high antithrombiin activity. The invention also provides DNAs encoding the amino acid sequence of hirudin analogs, expression vectors, recombinant microogranisms, and a method of manufacturing hirudin analogs using recombinant microorganisms.
