Q
What is H2S production testing?
A
H2S production testing is a test used to differentiate bacteria based on their ability to reduce sulphur containing compounds to hydrogen sulphide.
2
Q
What is the basis of H2S production testing?
A
The basis of H2S production testing is that hydrogen sulphide gas is produced from sulphur containing compounds which reacts with the ferric iron in the medium to create ferric sulphide which is a black precipitate.
