There are also various limitations of using serial dilution in microbiology.
Serial dilution doesn't separate bacteria similar to a streak plate, since it doesn't physically isolate or separate bacteria.
It also requires a longer period of time, and overnight incubation is sometimes required, limiting the efficiency of this technique.
Errors may occur in transferring the sample during propagation, causing less accurate and less precise dilution. This impacts the highest dilution the most, resulting in the least accuracy.
This technique requires highly skilled researchers and experts proficient in aseptic techniques.
