Perhaps fluorescence would be used because B. athracis has a cell wall making it difficult to visualize the details of the cytoplasm by simple bright field microscopy. Flourescence allows for labeling of specific entities, and "cold" illunimation of those entities against a dark field.
Bacillus anthracis is considered a biological weapon due to its ability to form highly resistant spores that can be dispersed in the environment easily. When inhaled, ingested, or coming into contact with open wounds, these spores can cause severe, often fatal, anthrax infection. Additionally, the bacteria can be engineered to be more virulent and resistant to treatments, increasing its potential for use as a weapon.
Robert Koch used Bacillus anthracis, the causative agent of anthrax, to develop his postulates. These postulates are a series of criteria used to establish a causative relationship between a microorganism and a disease.
To determine whether a cell contains mitochondria, a scientist should perform a microscopy technique, such as fluorescence microscopy, using specific stains that bind to mitochondrial components, like mitochondrial DNA or proteins. Alternatively, they could use electron microscopy for a more detailed view of the cell's ultrastructure. Additionally, isolating cell fractions and conducting biochemical assays to measure mitochondrial activity can provide further confirmation of their presence.
The easiest microscope to use for observing cell membranes is a fluorescence microscope. This type of microscope allows for the visualization of specific proteins or lipids in the cell membrane by using fluorescent dyes or tags, which can highlight structures that may be difficult to see with traditional light microscopes. Fluorescence microscopy also provides better contrast and resolution for cellular components, making it ideal for studying dynamic processes in living cells.
To determine whether a cell contains mitochondria, a scientist can use microscopy techniques such as fluorescence or electron microscopy to visualize the organelles. They may also employ specific staining methods that highlight mitochondrial structures, such as using MitoTracker dyes. Additionally, biochemical assays can be performed to measure mitochondrial function or the presence of mitochondrial DNA. These approaches collectively help confirm the presence of mitochondria within the cell.
Autoclaving
Bacillus are the type of bacteria which are causative agents of food poisoning. e.g. Bacillus Anthracis
A dichroic mirror enhances fluorescence microscopy by selectively reflecting and transmitting specific wavelengths of light. This allows for better separation of excitation and emission light, resulting in improved image quality and contrast in the final fluorescence image.

A condenser is not used in epi-fluorescence microscopes because the excitation light is focused onto the sample from above, typically through the objective lens. The use of a condenser, which typically directs light from below the sample, is not necessary in epi-fluorescence microscopy as it would not contribute to the desired illumination and would interfere with the fluorescence detection.

Yes, you can use a C18 column and methanol as a mobile phase with fluorescence detector. Fluorescence detector is generally used as it can detect the presence of compounds at a very low concentration.
