Studies on Bacterial Nutrition: IV. Effect of Plant Tissue upon Growth of Pneumococcus and Streptococcus
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 fourth article resulting from a long series of studies
on bacterial nutrition that Avery conducted, first with Thjotta and then Hugh Morgan, the scientists found that the presence
of unheated plant tissue in the media resulted in a remarkable acceleration in the growth curve of pneumococcus, and resulted
in longer-lived cultures of the bacteria.
