Bacteriological methods for freshwater samples are not suitable for saline water samples.

Bacteriological methods for freshwater samples are not suitable for saline water samples.

• A. True
• B. False
• C. Only for freshwater
• D. They require alternative protocols

Answer: (B)

The key idea is that the presence of salt can affect how bacteria grow and are detected, but freshwater methods are not automatically unusable for saline water. Many standard bacteriological methods can be applied to saline samples with the right adjustments or by using protocols designed for saline environments. For example, you can modify incubation conditions, use media that tolerate higher salt concentrations, or desalinate the sample before testing. Because these approaches allow freshwater methods to be used in saltwater contexts (often with modifications or alternative protocols), the statement that freshwater methods are not suitable is not accurate.
