Swimming efficiency of bacterium Escherichia coli.
We use measurements of swimming bacteria in an optical trap to determine fundamental properties of bacterial propulsion. In particular, we directly measure the force required to hold the bacterium in the optical trap and determine the propulsion matrix, which relates the translational and angular velocity of the flagellum to the torques and forces propelling the bacterium. From the propulsion m...
متن کاملI63. Triosephosphate Dehydrogenase of Bacterium Coli
THE Booth-Green wet-crushing mill for bacteria has been used previously to prepare a cell-free juice from Bacterium coli in which the components of enzyme systems may be studied. In the present paper a juice has been prepared containing the system which oxidizes 3-phosphoglyceraldehyde. For yeast it has recently been shown that the actual substrate is 1:3-diphosphoglyceraldehyde [Warburg & Chri...
متن کاملThe nutritional properties of killed Bacterium coli.
A previous investigation had shown that the protein and polysaccharide components of enteric bacteria can be separated by heating the cells in a watery suspension at 80" for I h (Roberts, 1949). In continuation of this work the protein of Bacterium coli was fed to rats and guinea-pigs and it was found that if the diet satisfied the peculiar vitamin requirements of the experimental animals, as, ...
متن کاملLxxvi. Indole Formation by Bacterium Coli
KuHNE [1875] recognised indole as one of the products of the bacterial decomposition of proteins. The discovery of tryptophan by Hopkins and Cole [1901] was followed by the proof by these authors that tryptophan was the parent substance of bacterially formed indole [Hopkins and Cole, 1903]. They succeeded in isolating indole and indoleacetic acid from the products of the aerobic growth of bacte...
