THE REACTION OF BACTERIA TO SOME HEMOGLOBIN DERIVATIVES

The investigations were intended initially to answer the question whether and how hemoglobin and its derivatives can be changed and decomposed by bacteria. In addition to human blood, the pure derivatives -- heme, mesohemin, hematoporphyrin, mesoporphyrin and bilirubin -- were added to various nutrient media in average concentrations of the pigments of 11000 to 12000. The susceptibility to growth of the bacteria was tested on control culture media. The one original question then immediately became two because it was necessary to determine, first, how the bacteria react to the hemoglobin derivatives and, second, how the hemoglobin derivatives react to the bacteria.
