Immobilization of Paenibacillus polymyxa with biopolymers to enhance the production of 2,3-butanediol

Carrageenan-chitosan immobilization enables non-pathogenic Paenibacillus polymyxa to be a capable 2,3-butanediol producer with increased product formation rate, which has not been previously reported. This novel strategy offers promising alternative to traditional fermentation processes using pathogenic strains and can be further applied in co-cultivations for metabolite production, wastewater management and bioremediation.
