  • METHOD OF PRODUCING ISOPRENOID COMPOUND
    Publication number: 20210403954
    Abstract: Producing an isoprenoid compound by: 1) culturing an isoprenoid compound-forming microorganism in the presence of a growth promoting agent at a sufficient concentration to grow the isoprenoid compound-forming microorganism; 2) decreasing a concentration of the growth promoting agent to induce formation of the isoprenoid compound by the isoprenoid compound-forming microorganism; and 3) culturing the isoprenoid compound-forming microorganism to form the isoprenoid compound, is characterized in that the growth phase of the isoprenoid compound-forming microorganism is separated from the formation phase of the isoprenoid compound.

  • Method of producing isoprene monomer
    Patent number: 10184137
    Abstract: A host cell includes a heterogeneous expression unit including: (a) a polynucleotide encoding a mevalonate kinase derived from a microorganism belonging to a genus selected from Methanocella, Corynebacterium, Methanosaeta, and Nitrosopumilus, and (b) a promoter operatively linked to the polynucleotide. The host cell is used to produce mevalonate kinase, mevalonate-5-phosphate, and isoprenoid compounds.

  • METHOD FOR PRODUCING POLYISOPRENE
    Publication number: 20180291127
    Abstract: A method for producing polyisoprene comprising: polymerizing isoprene by using an isoprene-containing composition containing isoprene and an oxygen-containing neutral compound, and a polymerization catalyst composition containing a rare earth element compound and an organometallic compound, wherein: —a compounding amount of the organometallic compound is 0.6 to 3.0 parts by mass per 100 parts by mass of the isoprene-containing composition.
