Studies on Bacterial Nutrition

Abstract

1. Certain anaerobic bacteria grow under aerobic conditions in plain broth in the presence of sterile unheated plant tissue. 2. Aerobic growth of anaerobic bacteria under the above conditions may be related to the presence of growth-accessory substances, and to the action of oxidizing-reducing systems of plant tissue in the destruction of toxic peroxides of bacterial origin.

The Interrelation of the Amount of V-factor and the Amount of Air Necessary for Growth of Hemophilus influenzae Type b in Certain Media

“…More recently, it has been reported that under anaerobic conditions the X-factor is not essential for growth. (Kopp (1927-8), Eirund (1929), andAnderson (1931).) Kopp has suggested that the X-factor has the property of protecting the influenza bacillus from the action of oxygen which is harmful to it.…”
