Acidic Conditions Are Not Obligatory for Onset of Butanol Formation by Clostridium beijerinckii (Synonym, C. butylicum).
Factors that may initiate the metabolic transition for butanol production were investigated in batch cultures of Clostridium beijerinckii (synonym, Clostridium butylicum) VPI 13436. Cultures maintained at pH 6.8 produced nearly as much butanol as those incubated without pH control, indicating that neither a change in the culture pH nor acid conditions per se are always required to initiate solv...
متن کاملButanol production from wheat straw hydrolysate using Clostridium beijerinckii.
In these studies, butanol (acetone butanol ethanol or ABE) was produced from wheat straw hydrolysate (WSH) in batch cultures using Clostridium beijerinckii P260. In control fermentation 48.9 g L(-1) glucose (initial sugar 62.0 g L(-1)) was used to produce 20.1 g L(-1) ABE with a productivity and yield of 0.28 g L(-1 )h(-1) and 0.41, respectively. In a similar experiment where WSH (60.2 g L(-1) ...

متن کاملButanol production from agricultural residues: Impact of degradation products on Clostridium beijerinckii growth and butanol fermentation.
During pretreatment and hydrolysis of fiber-rich agricultural biomass, compounds such as salts, furfural, hydroxymethyl furfural (HMF), acetic, ferulic, glucuronic, rho-coumaric acids, and phenolic compounds are produced. Clostridium beijerinckii BA101 can utilize the individual sugars present in lignocellulosic [e.g., corn fiber, distillers dry grain solubles (DDGS), etc] hydrolysates such as ...
متن کاملHydrogenase of Clostridium butylicum.
Significant differences in the properties of hydrogenases from various sources have been described, even in preparations derived from different bacteria within a single genus. Thus, the cell free hydrogenases of Clostridium butylicum (Koepsell and Johnson, 1942) and Micrococcus aerogenes (Curtis and Ordal, 1954) are incapable of reducing commonly used two-electron dye acceptors such as methylen...
