Quizplus · Accepted Answer

Fluorescent microscopy is a rapid technique that can be used to detect and differentiate specific classes of microbes in a drop of seawater. This is achieved by labeling the microbes with fluorescent dyes and visualizing them under a fluorescent microscope. The technique is quick, sensitive, and can provide information on the morphology, size, and abundance of the microbes. Metagenomics and DNA/RNA sequencing are powerful techniques but are more time-consuming and require complex data analysis. Viable plate count is not suitable for detecting all classes of microbes and can underestimate the microbial diversity present in the sample. Radiography is not applicable for detecting microbes in a drop of seawater.
