Studies on Bacterial Nutrition: III. Plant Tissue, as a Source of Growth Accessory Substances, in the Cultivation of Bacillus
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 third article resulting from a long series of studies
on bacterial nutrition that Avery conducted with Thjotta and Hugh Morgan, the scientists found that growth accessory substances
which occur in human blood were also present in plant and animal tissue. They argued that the observation of the growth of
"so-called" hemophilic bacteria on blood free media demonstrated that other substances could function in the same
manner as the growth-inducing factors in blood.
