Bacterial Grouping
One of the 3 example shapes/formations of gram positive cocci.
What are clusters, chains, or tetrads?
This is another term for liquid media.
What is broth?
This kingdom of eukarya includes yeast, molds, and mushrooms.
What is fungi?
This tool is used to heat and sterilize.
What is a Bunsen burner?
This is the most diverse domain of life.
What is archaea?
One of the 3 example shapes/formations of gram positive bacilli.
What are thick, thin, or branched?
This type of solid media is used to isolate individual colonies of bacteria using a large surface space.
What are petri plates?
These cells are used by researchers to investigate how normal cells behave.
What are primary cells?
This is the color presented by gram negative bacteria.
What is pink/red?
This is a protein that is artificially produced (man-made) in a genetically engineered organism.
What is recombinant protein?
This is an example of gram negative cocci.
What is diplococci?
This is the area surrounding antimicrobial disks where bacteria does not grow.
What is the zone of inhibition?
This term means capable of becoming a different cell. A stem cell is this.
What is pluripotent?
This step is a part of staining techniques to bond cells to slides and sterilize samples.
What is heat fixation?
*Used in simple stain, gram stain, and acid fast.
*Not used in negative staining.
This scientist increased microscope magnification from 25x to 200x and coined the term "animalcules."
Who is Anton van Leeuwenhoek?
One of the 3 example shapes/formations of gram negative bacilli.
What are thin rods, curved, or thin needle shape?
Media should be labeled (at minimum) with these 4 labels.
What is:
-name of microorganism
-initials of person who inoculated
-date of inoculation
-type of agar
These genetically modified cells are used in biotech research because they grow indefinitely/are immortal.
What are cell lines?
These 4 stains/chemicals are used in gram staining (besides water).
What are:
-crystal violet
-iodine
-alcohol/ethanol
-safranin
The staining technique does not enter cells and the observer sees clear or white cells on a black or gray background.
What is negative stain?
This specific type of bacteria cannot be gram stained.
What is spirochete?
*Spiral is too broad and not correct. Spirillum and vibrio are gram negative spiral.
This type of solid media is used to look at motility and gas requirements of bacteria by observing where they grow and whether they move through the agar away from the stab.
What are deep tubes?
This term means capable of regenerating from a single cell. A plant cell is this.
What is totipotent?
This value is measured using a spectrophotometer.
What is optical density?
OD: how cloudy a culture is
This type of bacteria has an ideal growth temperature range of 45°C to 80°C.
What is thermophilic bacteria?
