Studies on Oxidation-Reduction Potentials (ORP) of Microbial Cultures

Clxx. Oxidation-reduction Potentials of Pneumococcus Cultures. I. by Leslie

THE oxidation-reduction potentials established in cultures during the growth of various bacteria under different conditions have been described in previous communications. By extending these studies to other bacteria it is hoped to reveal the general effects of cultural conditions and the individual differences between different organisms. Serum proteins have an inhibiting effect on the establi...

Oxidation-Reduction Potentials

In the first part of the book purely physico-chemical considerations of redox potentials are lucidly and thoroughly dealt with, and in the second part their applications to physiology are systematically developed. To a student of physiology, who is not well versed in the principles of electrochemistry, this book will be of great value as the author initiates the reader first into those parts of...

Studies on Oxidation and Reduction by Pneumococcus. I. Production of Peroxide by Anaerobic Cultures of Pneumo-

The previous studies by McLeod and Gordon (1) and by Avery and Morgan (2) on the production of peroxide by pneumococcus have dealt with the formation and accumulation of this substance during active aerobic growth. The present paper presents a study of the production of peroxide by cultures in which its formation has been prevented during active growth, and in which the subsequent production of...

Studies on the Oxidation - Reduction of Hemo

The apparently spontaneous conversion of hemoglobin to methemoglobin is an occurrence that has been recognized ever since the discovery of the latter blood pigment (Hoppe-Seyler, 1864). Although certain bacteria can oxidize hemoglobin to methemoglobin, the alteration of hemoglobin observed by the chemist is probably rarely due to bacterial action. Indeed, this conversion can occur in the comple...
