The crude histaminase preparation obtained from guinea pig skin was fractionated by Sephadex G-200 at 4°C and 55°C. The histaminase activity corresponded to the descending limb of the :first peak of protein eluted just after void volume at 4°C and to the second peak at 55°C. The histaminase activity in the fractions eluted at 4°C was higher at 55°C than at 37°C. On the contrary, no significant ...

Elion (1924) was the first to isolate a thermophilic sulfate reducing bacterium in pure culture. He named the organism Vibrio thermodesulfuricans, and reported that it was capable of sulfate reduction betveen 30 and 65 C, wvith an optimum of 55 C. Baars (1930) and Kluyver and Baars (1932) reisolated V. thermodesulfuricans, and carried out a comparative study of this organism and Vibrio desulfur...

Anaerobic biodegradation tests of poly(lactic acid) (PLA) powder were done at the thermophilic (55 degrees C) and mesophilic temperature (35 degrees C) under aquatic conditions [total solid concentrations of the used sludge were 2.07% (at 55 degrees C) and 2.24% (at 35 degrees C)] using a newly developed evaluation system. With this system, the evolved biogas is collected in a gas sampling bag ...
