A gene expression cassette capable of producing psicose at high yield with high stability, a GRAS(Generally recognized as safe) microorganism, a method of producing the enzyme by using the GRAS microorganism, and a method of producing the psicose by using the GRAS microorganism and enzyme are provided.


Patent
Samyang Corporation | Date: 2014-04-15

A novel the Ensifer adhaerens strain isolated from soil and a method of producing psicose using the same are provided.


The present invention relates to a polysulfone copolymer with excellent heat resistance and chemical resistance, and a method for preparing the same and, more specifically, to a polysulfone copolymer and a method for preparing the same, wherein the polysulfone copolymer comprises, as repeat units, a sulfone-based compound, and an anhydrosugar alcohol, which is a biogenic material, and thus the polysulfone copolymer can solve a problem of an exhaustion of petroleum resources, which are limited resources; does not emit carbon dioxide regardless of the disposal after use, and thus is eco-friendly; and has significantly improved heat resistance and chemical resistance compared with existing polysulfone copolymers.


Patent
