Employing a system for continued pH adjustment and a growth medium containing factors essential for streptococcal growth and SI O production, the formation of SI O at different growth phases was studied. The SI O formed during the early phase of exponential growth could not be completely neutralized by its corresponding antibody thus indicating a lack of or a lower antigenicity of this streptolysin. The mechanism for SI O formation is probably an active process where a feed back system might be involved.
