On the 30th, Yokohama Rubber Co., Ltd. announced that it has developed the "world's first" technology to efficiently produce isoprene from biomass (isoprene is a raw material for the production of synthetic rubber), and the company also said This technology can also be applied to the manufacture of butadiene synthetic rubber as well as other diene rubbers.
In 2013, Yokohama Rubber and Riken Research and Ryan Chemical began the study, using a computer-based metabolic design technique to discover a new isoprene synthesis process within two years.
Yokohama said that the three parties have further developed this new technology, based on a highly active enzyme created by it, which has produced cells with "excellent isoprene synthesis", which have been produced in the body. The ability of a substance (usually a sugar) to form isoprene to polymerize isoprene produced in a cell, thereby realizing the synthesis of a polyisoprene rubber.
Yokohama added that isoprene is generally thought to be naturally produced by pentanoic acid, an intermediate formed by sugars, through a five-stage reaction, but its new artificial channel constructed by joint research can reduce this process to two. segment.
The company also said that this highly active enzyme has the amazing ability to generate isoprene that is not possible with natural enzymes. By introducing these enzymes into E. coli, bacteria are able to produce isoprene. Isoprene is currently produced primarily by thermal cracking of naphtha.
