The Effects Of Myoglobin, Nitrosylmyoglobin, And Free Iron On The Growth Of Clostridium Botulinum In Cured Meat, Susan K. Fortier Collinge
The Effects Of Myoglobin, Nitrosylmyoglobin, And Free Iron On The Growth Of Clostridium Botulinum In Cured Meat, Susan K. Fortier Collinge
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Although nitrite is a known inhibitor of Clostridium botulinum in cured meats, the mechanism of inhibition is not understood. The observation has been made that iron is required for growth of C. botulinum and that the role of nitrite may be to alter the pathway of iron uptake by these organisms. Since the color change in cured meats is due to the binding of nitrite to the heme group of meat pigments, it was hypothesized that nitrite may also be tying up an essential iron source, heme. This experiment was an investigation of the possibility that myoglobin added to a …
