Shepard, Charles C. (Communicable Disease Center, Atlanta, Ga.). Temperature optimum of Mycobacterium leprae in mice. J. Bacteriol. 90:1271-1275. 1965.-Mycobacterium leprae multiplied most rapidly in foot pads of mice kept at an air temperature of 20 C. At air temperatures of 15 and 25 C, bacillary multiplication was slightly slower; at 10 and 30 C, distinctly slower; and at 4 and 35 C, no baci...

In order to obtain basic design criteria for anaerobic digesters of swine manure, the effects of different digesting temperatures, temperature shocks and feed loads, on the biogas yields and methane content were evaluated. The digester temperatures were set at 25, 30 and 35 degrees C, with four feed loads of 5%, 10%, 20% and 40% (feed volume/digester volume). At a temperature of 30 degrees C, t...

A new strain of Prototheca zopfii Krüger was grown on acetate or on pure n-alkanes. A maximum acetate-supported exponential growth of 12 divisions day occurred at pH 5 and 30 degrees C. At 25 degrees C, growth on n-alkanes was almost as fast, but no growth occurred at 30 degrees C. After 4 days at 25 degrees C, 34 to 45% of the n-alkanes had been removed, whereas at 21 degrees C and slower grow...

The effect of temperature on the embryonic development of three populations of reniform nematode (Rotylenchulus reniformis) from the southeastern United States was studied. The development of eggs from single-cell stage to eclosion of second-stage juvenile was monitored at 20, 25, 30, and 35°C. All populations completed embryogenesis in 7 days at 25°C. The greatest differences among populations...
