Significance of Optical Density Measurement
Optical Density Measurement is a technique for quantifying the concentration of substances in culture media by assessing light absorbance at designated wavelengths. It is particularly useful for estimating bacterial growth in E. coli cultures through spectrophotometric analysis, providing numerical values for cell populations. This method allows researchers to determine cell concentration effectively by measuring absorbance, making it an essential tool in microbiological studies.
