The production of 2, 3-butanediol and succinic acid by a moderate halophile under anaerobic condition was investigated. This halophile, termed Salinivibrio YS, was isolated from the solid samples collected from Aydingkol Lake. Based on the single factor experiment, the parameters

Fed-batch fermentations for the production of 2,3-butanediol (BDL) with Paenibacillus polymyxa DSM 365 were investigated in 2-L-fermenters. A suitable micro-aerobic set-up enabled high product selectivity of up to 98% R,R-BDL towards meso-BDL and acetoin. Up to 111 g L(-1)R,R-BDL within

Paenibacillus polymyxa can produce the (R,R)-stereoisomer of 2,3-butanediol (2,3-BDL) which is industrially very useful. Two important factors affecting (R,R)-BDL production by P. polymyxa ATCC 12321, medium composition, and addition of acetic acid to the culture were investigated in this study
