What else can I help you with?
Which microscope would be MOST useful for examining the contours of the surface of a bacteria cell?
It depends on the type of biofilm, what surface the biofilm is on, and what information you want to get by looking at the biofilm under a microscope. If you just want to look at how much of a surface is covered by a biofilm, you can use normal light trasmission microscopy (as long as the surface is transparent e.g. glass). Alternatively you could use epifluorescent microscopy in combination with a fluorescent stain. If you want to look at the structure of the biofilm, confocal laser scanning microscopy is probably the best as you can get a 3D image. Other useful types of microscopy include phase contrast and DIC, which allow you to look at the biofilm without staining it first.
What are the most effective methods for treating pseudomonas biofilm infections?
The most effective methods for treating pseudomonas biofilm infections include using antibiotics, combination therapy, biofilm disruptors, and antimicrobial peptides. These treatments can help to break down the biofilm and target the bacteria causing the infection.
Is a natural biofilm a pure culture?
A biofilm may consist of a single species embedded in extracellular polymeric substance (EPS), or it may consist of multiple species. The monospecies biofilm does constitute a 'pure' culture, and these do occur under natural circumstances, as for example, H. pylori biofilm in the human stomach (Cole et al (2004) Characterization of Monospecies biofilm formation by Helicobacter pylori," Journal of Bacteriology 186:3124-3132). However, most biofilms that people are familiar with - pipe slime, tooth plaque, etc. - include multiple bacterial species, and can include algae and/or fungus.
Which organelle in a eukaryotic cell is most noticeable under a microscope?
The nucleus is the most noticeable organelle in a eukaryotic cell under a microscope due to its size and distinct structure. It appears as a large, round structure typically located in the center of the cell.

How do you separate fungal cells from biofilm?
Remove the biofilm from the surface first. They best way to do that depends on the surface. Get the biofilm into water or PBS. Put some small (~2 mm diameter), sterile glass beads in the tube. Vortex for about 30 seconds or so (you will need to optimise this). This should separate most of the cells from the biofilm matrix. Now it depends on what you want the cells for. If you just want to count them, you could use something like FISH and count the cells under a fluorescence microscope, or using FACS. If you want individual cells, that is trickier.
What lab instrument would be most useful for looking at large insects collected in pit traps.?
dissecting microscope
Which lab instrument would be most useful for looking at large insects collected pit traps?
disecting microscope
Which microscope would be most useful for quickly estimating the number of red blood cells in a patient's blood sample?
compound light
What are some useful applications for a pocket microscope?
Some of the best and most useful applications for a pocket microscope are typically in an instruction setting. Children are best suited for these types of microscopes as they can learn during science classes, for field trips, and other endeavors. These microscopes are versatile enough for medical personnel as well.
What unit of metric measurement is most useful for light microscopy?
The unit of metric measurement most useful for light microscopy is the micrometer (μm), which is one-thousandth of a millimeter. This unit allows for precise measurements of objects that can be visualized under a light microscope.
What is the most powerful type of microscope?
electronic microscope
Which microscope would most likely show the most detail?
scanning electron microscope
Since plays were meant to be performed is one of the most important skills a reader can employ?
visualizing
