Abstract
The interdependence of the factors temp., time and pH was investigated, using 0.3-0.5% extracts by weight of the style of Pecten maximus. For periods of 8-51 hrs. the optimum pH remained constant at 6.5. At a pH of 7.3 the optimum temp. is 38[degree]C; at pH 6.2, 36[degree] C; at pH 4.8, 26[degree] C; the more alkaline the medium the higher the optimum temperature. When the time of the experiment is made equal to the time the food is in the gut of the animal (10 hrs.), and when the temp. is made equal to that at which the animal normally lives (13[degree] C), the optimum pH is found to be that actually in the gut (6.0).This publication has 2 references indexed in Scilit:
