Does the number of bacteria recorded by the standard plate count method accurately reflect the total bacterial count from the sample?

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.

How does Pine-sol kill bacteria?
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
Do bacterial cells have a cell membrane?
Yes, the standard bi-lipid layer, and/plus an exterior, strong, Cell wall.Yes, and the cell membranes are usually covered by cell wall as well.
What are the steps to perform minimum inhibitory concentration test?
hellos, I'm currently handling a project dealing in Minimum inhibitory concentration and minimum bactericidal concentration. Had to create the whole protocol from scratch. what's the Standard protocol used when dealing MIC test on bacterial like E.Coli and S.aureus?
How often do bacteria reproduce?
It depends upon the environmental conditions and the particular species, but as a general Answer: Exponentially. Specifically, under Ideal {standard laboratory} Conditions, an E-coli bacterium will [repeatedly] reproduce once during each (and every continuing) 20 minute interval(s).
What is the first step in the identification of any unknown bacterium?
Personally, I prefer to gram stain the bacteria. However other like to find out what it's respiratory orientation is first (whether it is anaerobic, facilitative or aerobic). There is really no standard way, just do what you feel is best, as long as you do all of them at some point.
What is a standard solution?

How do you identify bacterial cells that have taken up your gene of interest?
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.
A solid acid of high purity that can be accurately weighed and directly determined is called?

In statistics what is SE?
SE is the standard error. it is the standard deviation divided by the square root of sample size. It basically measures how accurately a statistic describes the population.
What is standard delivery?
Standard delivery - is normal postal delivery - as opposed to special, recorded or courier delivery.

Small standard deviation show what the disturbution?
It shows primarily that the measurement unit used for recording the data is very large. For example, the standard deviation of the heights of individuals, when recorded in metres, will be one hundredth of the standard deviation of their heights when recorded in centimetres. The process is known as coding.
