Studies on Bacterial Nutrition: I. Growth of Bacillus Influenzae in Hemoglobin-Free Media
Over the early 1920s, several researchers in Avery's laboratory at Rockefeller Hospital turned their attention to certain
bacteria, such as Bacillus influenzae, which had previously only been grown in media containing blood or blood derivatives.
Because of this, the bacteria were termed "hemophilic." In this first in a series, Thjotta shows that B. influenzae
will grow on hemoglobin-free medium consisting of plain broth enriched by sterile suspensions of mucoid bacteria. He suggests
that under these conditions growth may be attributed in part to the presence of specific bacterial extracts.
