In the case of S. sanguis, the products became even more oxidized at higher oxygen concentrations, and carbon dioxide was formed instead of formate. Minute amounts of oxygen were supplied to a continuous cultivation of Lactococcus lactis subsp. With increasing oxygen concentrations the degradation products from glucose become more oxidized.

ScienceDirect ® is a registered trademark of Elsevier B.V. lactis MG1363 was grown in batch cultures on a defined medium with glucose as the energy source under different aeration conditions, namely, anaerobic conditions, aerobic conditions, and microaerobic conditions with a dissolved oxygen tension of 5% (when saturation with air was used as the reference).

Both streptococci consumed large amounts of oxygen by the partial oxidation of sugars, thus maintaining an anaerobic environment.

“Streptococcus is generally found wherever natural substances that contain sugars are accumulated. Why don't libraries smell like bookstores?

Sudden increase in the oxygen concentration in the gas phase caused elevated oxygen tensions in the cultures, which led to a decrease in the growth rate of the streptococci.
