Phosphatidylserine decarboxylase from Clostridium butyricum.

Phosphatidylserine decarboxylase from Clostridium butyricum.

Phosphatidylserine decarboxylase activity has been characterized in membrane preparations from Clostridium butyricum ATCC 19398. A particulate fraction was shown to catalyze the formation of phosphatidylethanolamine and plasmenylethanolamine when vesicles containing phosphatidylserine and plasmenylserine were used as substrate. No plasmenylethanolamine was formed when phosphatidylserine alone w...

The amylase of Clostridium butyricum.

Selective medium for isolation of Clostridium butyricum from human feces.

A selective medium, Clostridium butyricum isolation medium (BIM), is described for the isolation of C. butyricum from human feces. The BIM is a synthetic minimal medium and contains trimethoprim (16 micrograms/ml), D-cycloserine (10 micrograms/ml), and polymyxin B sulfate (20 micrograms/ml) as selective inhibitory agents. Qualitative tests indicated that C. butyricum and other butyric acid-prod...

Biotechnological potential of Clostridium butyricum bacteria

In response to demand from industry for microorganisms with auspicious biotechnological potential, a worldwide interest has developed in bacteria and fungi isolation. Microorganisms of interesting metabolic properties include non-pathogenic bacteria of the genus Clostridium, particularly C. acetobutylicum, C. butyricum and C. pasteurianum. A well-known property of C. butyricum is their ability ...

Reversal of pyruvate oxidation in Clostridium butyricum.

The failure to detect an equilibrium between acetyl phosphate, a product of pyruvate cleavage, and pyruvate has been one of the poorly understood observations of the pyruvate cleavage reactions in Clostridium butyricum and in Escherichia coli (l-3), although pyruvate synthesis from acetyl phosphate was reported in the latter organism (4). In the preceding paper (5) a small incorporation of acet...
