The Oxygen Consumption of Luminous Bacteria
Oxygen consumption of luminous bacteria determined by the Thunberg micro respirometer and by the time which elapses before the luminescence of an emulsion of luminous bacteria in sea water begins to dim, when over 99 per cent of the dissolved oxygen has been consumed, agree exactly. Average values for oxygen consumption at an average temperature of 21.5 degrees C. are 4.26 x 10(-11) mg. O(2) pe...
متن کاملThe Respiration of Luminous Bacteria and the Effect of Oxygen Tension upon Oxygen Consumption
1. The respiration of luminous bacteria has been studied by colorimetric and manometric methods. 2. Limulus oxyhaemocyanin has been used as a colorimetric indicator of oxygen consumption and indicator dyes were used for colorimetric determination of carbon dioxide production. 3. The Thunberg-Winterstein microrespirometer has been used for the measurement of the rate of oxygen consumption by lum...
متن کاملThe Minimum Concentration of Oxygen for Luminescence by Luminous Bacteria
A method is described for measuring the concentration of oxygen to allow just perceptible luminescence of luminous bacteria. The value turns out to be extraordinarily low, about 0.005 mm. Hg pressure O(2) or 1 part by weight oxygen dissolved in 3,700,000,000 cc. sea water.
متن کاملThe Total Luminous Efficiency of Luminous Bacteria
Methods are described for measuring the light emitted by an emulsion of luminous bacteria of given thickness, and calculating the light emitted by a single bacterium, measuring 1.1 x 2.2 micra, provided there is no absorption of light in the emulsion. At the same time, the oxygen consumed by a single bacterium was measured by recording the time for the bacteria to use up .9 of the oxygen dissol...
متن کاملStudies on Luminous Bacteria
1. A method has been described whereby the intensity of the light of luminous bacteria may be measured in a quantitative manner. 2. It is pointed out that the temperature coefficients for light intensity do not follow the van't Hoff rule, but are higher and vary with each 10 degrees temperature interval. 3. From a comparison with other data it is found that the process is not a simple one, but ...
