Introduction: In microbiology, the presumptive test is used to find out whether gas-forming lactose fermenters (coliform bacteria) are available in the water sample.

Expert Solution & Answer

Explanation of Solution

If positive results are observed from the water sample used during presumptive analysis, it does not mean that the water is unsafe to drink. Gas formation might have occurred due to other non-coliform bacteria. Therefore, to confirm that water is unsafe to drinking, further testing is required after a positive presumptive test.
