Capital Investment Operating Cost of Butanediol Plants. Butanediol (also known as BDO and 1,4-Butanediol) refers to all butylene glycol isomers. Addition of acetic acid in the medium induced the production of 2,3- butanediol by 2-fold. Two-step aerobic-anaerobic fermentation further enhanced 2,3- butanediol production by 4-fold in comparison to the control parental strain.

Optimization of kla profile. Appl.Development of an industrial medium for economical 2,3-butanediol production through co-fermentation of glucose and xylose by Klebsiella oxytoca. A new industrial production method of 2, 3-butanediol is discussed in this paper.C 2-4 bio-polyol is prepared by combining biological fermenta-tion and chemical cleavage, with corn starch as raw material. These studies demonstrated that optimization of media components and culture condi-tions are important for 2,3-butanediol production. The traditional method of optimization involves varying one factor at a time, while keeping the others constant. The strain B. licheniformis, WX-02, used in this study was previously isolated for the production of -PGA with 2,3-butanediol and acetoin being the co-products. This strain can grow in a simple medium containing glucose, glutamic acid, and mineral salts [14]. The acetoin can be oxidized to 2,3-butanedione (diacetyl) by O2 present in the fermentation medium, or enzymatically reduced (with NADH as a cofactor) to 2,3-BD.2,3-Butanediol production of immobilized Enferobacter aerogenes IAM1133 with -carrageenan.J.
