N2 - Seven of eight type strains of Streptococcus bovis, including all 6 rumen isolates tested, produced pigment on agar media if the anaerobic atmosphere was supplemented with CO2. Tween 80 or NaHCO3 added to the growth medium could not substitute for gaseous CO2. When one of the best pigment-forming strains, S. bovis 2B, was grown in a glucose-limited chemostat at constant dilution rate (D), decreasing the concentration of the gas overlay resulted in pigment washout and increased lactate and cell mass. Champing pH at a constant D altered the pigment production and glucose end products of the culture.
