There's no need to swallow oxygen...
The intestinal flora of a healthy individual normally consists of
90-99% anaerobic bacteria (Eubacterium, Bacteroides, Fusobacterium,
Coprococcus etc.) and only the rest are (facultative) aerobic species
such as E. coli, other Enterobacteria, Enterococcus..
The microbes are distributed within the lumen of the gut due to their
needs.  Anaerobic ones will be found in the middle of the lumen where
oxygen is low, aerobic ones can only live near the
intestinal wall where they are supplied with oxygen from blood
circulation.

Best regards,
