“…Increasing the surface to volume ratio, previously reported to be beneficial to diol production (Adams and Leslie, 1946), did not improve dlol yields in the above medium. Consequently, the medium of Stanier and Adams (1944), a medium in which B__L. pol~mxa was reported to ferment xylose to dlol (Adams and Stanler 1945), was tested at a 1% w/v xylose level.…”

2,3-Butanediol production from xylose and other hemicellulosic components by Bacillus polymyxa

1984

In the xylose fermentation of Bacillus polymyxa strain 9035, best 2,3-butanediol yields were obtained with 1.0% yeast extract, 4-6% xylose, shaking at 125 rpm and incubation at 30°C.Under these conditions, mannose, galactose, L-arabinose, cellobiose, starch and glucose were readily metabolized and yielded significant amounts of diol.Diol production from xylan was also demonstrated. In addition, the screening of a number of B___tpolymyxa strains on xylose revealed that only strains 9031-1 and 9035 used xyiose extensively and produced significant amounts of diol.The latter strain proved best under scaled-up conditions.

The effect of yeast extract on the fermentation of glucose to 2,3-butanediol by Bacillus polymyxa

The fermentation of glucose to 2,3-butanediol by Bacillus polymyxa was improved by increasing the amount of yeast extract in the culture medium. A level of 1.5% (w/v) resulted in optimal 2,3-butanediol production.A comparable fermentation could be achieved with 0.5% yeast extract if the phosphate level of the medium was increased from 0.0026 to 0.078 M and the medium was supplemented with 40 ~M iron and 1.7 ~M manganese.

The concomitant occurrence of molecular hydrogen (H 2 ) and organic acids along the alimentary canal of the earthworm is indicative of ongoing fermentation during gut passage. Fermentative H 2 production is catalyzed by [FeFe]-hydrogenases and group 4 [NiFe]-hydrogenases in obligate anaerobes (e.g., Clostridiales) and facultative aerobes (e.g., Enterobacteriaceae), respectively, functional groups that might respond differently to contrasting redox conditions. Thus, the objectives of this study were to assess the redox potentials
