Please, study the experience of professionals (three manuscript in Attachment).

Using cell counting and optical measurements have been proven to be best methods. Please, kindly read more on this in the attached article. Kind regards

I wish you good luck.

There are many ways to measure bacteria growth, and some are more complex than others. Though you sacrifice some consistency in your measurements, the simplest methods are accurate enough and used commonly. The most well-known methods are observing and counting the bacteria, measuring wet or dry mass, and measuring turbidity.

Method 1: Observing Bacteria Directly.

Method 2 : Measuring Wet and Dry Mass.

Method 3: Measuring Turbidity .

There have been many developments over the years. However , serial dilution plate method stands out to be the best method for measuring culturable bacteria.
