Uricase and its action

THE experiments described in Part I of this series [Przy1gcki, 1928, 1930], dealing with the relative activity of variously purified preparations of uricase and with the action of inhibitory substances, led, except in the case of glycerol-chloroform extracts, to results inconsistent with enzyme action, but consistent with bacterial decomposition. The presence of bacteria has now been demonstrated, these bacteria have been identified, and certain of their conditions of viability have been investigated, with a view to a critical application of the observations to the results described in Part I and to those of earlier workers in this field.
