본발명에따른신규미생물인JRM28-A는셀로바이오스와자일로스를기질로이용하여글루코스에의한탄소이화작용산물억제작용을이완시킬수 있다. 상기JRM28-A는셀로바이오스와자일로스를동시에소모하며발효할수 있어현저히증가된자일로스의이용속도를나타낸다. 따라서본 발명에따른JRM28-A를이용하면베타-글루코시다제와같은효소를사용하지않고도 2,3-부탄다이올의전구체인아세토인과같은바이오화학물질또는바이오연료를효과적으로생산할수 있다.

Abstract:
The present invention provides a method for producing 2,3-butanediol, in which Klebsiella oxytoca M1 (KCCM11177P) is modified with genes to increase the production yield of 2,3-butanediol, or a gene-modified Klebsiella oxytoca M1 recombinant strain. Furthermore, the present invention provides the method for producing 2,3-butanediol, which reduces the production of byproducts such as acetoin, and increases the production of 2,3-butanediole by controlling the culture conditions of the Klebsiella oxytoca M1 recombinant strain.
