Hello, I would like to know if there are any bacteria that can produce CO and are safe for humans

I know about the following ones:

Bacillus cereus

Proteus vulgaris

Proteus mirabilis

Morganella morganii

But they can all be responsible for opportunistic infections in humans and I could only find these in literature as CO producing ones. Is anybody aware of any other CO-producing bacteria?

I need this information for a literature review about bacteria that might be potentially useful in food applications.

Thank you
