Is Veillonella anaerobic or aerobic?

Explanation:
Veillonella are obligate anaerobes, meaning they can grow only in environments without oxygen and are inhibited or killed by atmospheric oxygen. In the mouth, they inhabit deeper plaque where oxygen is limited and they rely on lactate produced by other bacteria, fermenting it to short-chain acids. In laboratory settings, they require anaerobic or tightly reduced atmospheres to grow. They do not tolerate oxygen, so they are not aerobic, microaerophilic, or facultative.
