No. The standard plate count method is an indirect measurement of cell density of only viable bacterial cells. Optical density counting measure entire bacterial sample, the living as well as the dead bacterial cells.
One can accurately measure protein concentration in a sample using methods such as spectrophotometry, Bradford assay, or BCA assay. These methods involve measuring the absorbance of light by the proteins in the sample and comparing it to a standard curve to determine the concentration.

Pine sol actually does not kill bacteria... it doesn't even inhibit the growth of bacteria at all. in a recent experiment conducted. i tested 3 different concentrations of pine sol and compared it to bleach at full concentration, pine sol didn't inhibit growth at all. whereas bleach completely killed it. at 44% dilution, pine sol still hadn't stopped bacterial growth, whereas bleach still managed to kill of bacteria. at 12.5% concentration, pine sol, had actually allowed the colonies of bacteria to grow even closer together to mimic the "lawned" streaks. bleach had still managed to kill bacteria at 12.5% it should be kept in mind that in a standard lab, 10% bleach is used to sterilize and kill bacteria. i hope that answers your question, pine sol, actually doesn't inhibit the growth, nor kills it, but allows it to grow
Nanodrop protein quantification uses light absorption to measure protein concentration in a sample. The technique involves shining light through the sample and measuring how much light is absorbed by the proteins. By comparing the absorption to a standard curve, the protein concentration can be accurately determined.
Standard methods agar plates are routinely used in microbiology laboratories for culturing and isolating bacteria. These agar plates contain nutrients that support bacterial growth and are used to assess bacterial contamination in food, water, clinical samples, and environmental samples.
The standard plate count method is preferred for counting bacteria in food because it provides a simple and reliable way to determine the number of viable bacteria present. It allows for the cultivation of various types of bacteria which may be present in the sample, providing a more accurate representation of the bacterial population. Additionally, the standard plate count method is well-established, widely accepted, and can be easily standardized for regulatory purposes in the food industry.

A standard solution is a solution of known concentration that is used to determine the concentration of an unknown solution in a chemical analysis. It is often prepared by accurately measuring a known amount of solute and dissolving it in a known volume of solvent.
A standard solution in titration is a solution of known concentration that is used to determine the concentration of another solution. It is typically a primary standard that can be accurately weighed and dissolved to make a solution of precise concentration. Standard solutions are essential in titration to accurately measure the volume of the solution being titrated and calculate its concentration.
A standard test is the antibiotic resistance take up. This is where you confer resistance plasmids containing the gene of interest to bacterial uptake. So you use two antibiotics, Kanamycin and Penicillin, to test that your bacteria so infused is now resistant to these two antibacterial agents. A successful recombination exercise will lead to growth on this medium.

The relationship between optical density and bacterial cell count can vary depending on the species, growth phase, and experimental conditions. Therefore, it is not possible to directly equate one optical density reading to a specific number of bacterial cells without calibration against a known standard or a standard curve.
