Question

Coliforms and fecal coliform are often differentiated based on their responses to _________.
A)temperature

Therefore, temperature is often the key factor used to differentiate between the two types of bacteria. Salinity, pressure, and heavy metals are not typically used to differentiate between coliforms and fecal coliforms.
