  • Process for producing D-mannitol
    Patent number: 8338147
    Abstract: High concentration of free cells of heterofermentative lactic acid bacteria (LAB) in a resting or slowly growing state are used to convert fructose into mannitol. Efficient volumetric mannitol productivities and mannitol yields from fructose are achieved in a process applying cell-recycle, continuous stirred tank reactor and/or circulation techniques with native LAB cells or with LAB cells with inactivated fructokinase gene(s). Mannitol is recovered in high yield and purity with the aid of evaporation and cooling crystallization.
