METABOLISM OF PENTOSES BY CLOSTRIDIA II. Clostridium perfringens, Clostridium beijerinckii , and Clostridium butylicum

Metabolism of pentoses by clostridia. I. Enzymes of ribose dissimilation in extracts of Clostridium perfringens.

Evidence has accumulated indicating that the clostridia ferment glucose by means of a system similar to the Embden-Meyerhof-Parnas (EMP) pathway (Elsden, 1952). In the case of Clostridium perfringens, for instance, most of the enzymes of the EMP pathway have been demonstrated in cell free extracts (Bard and Gunsalus, 1950; Shankar and Bard, 1955). Further evidence for the operation of the EMP p...

Hydrogenase 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...

Emended descriptions of Clostridium acetobutylicum and Clostridium beijerinckii, and descriptions of Clostridium saccharoperbutylacetonicum sp. nov. and Clostridium saccharobutylicum sp. nov.

On the basis of 16S rRNA gene sequencing and DNA-DNA reassociation, industrial solvent-producing clostridia have been assigned to four species. In this study, the phenotypic characteristics of Clostridium acetobutylicum, Clostridium beijerinckii, 'Clostridium saccharoperbutylacetonicum', and an unnamed Clostridium sp. represented by the strains NCP 262T and NRRL B643 are compared. In addition, ...

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...
