Is b magaterium gram negative?
Bacillus megaterium is not gram-negative; it is a gram-positive bacterium. This classification is based on its thick peptidoglycan cell wall, which retains the crystal violet stain used in the Gram staining procedure. As a result, B. megaterium appears purple under a microscope after staining.
How many times more resistant were B megaterium spores than s aureus vegetative state?
Bacillus megaterium spores are typically thousands of times more resistant to harsh conditions compared to the vegetative state of Staphylococcus aureus. This increased resistance is due to the protective structures and dormancy of the spore form, allowing it to survive in unfavorable environments until conditions are more conducive for germination.
Which B Megaterium culture logarithmic or stationary phase would show the best survival following exposure to UV radiation?
The B. megaterium culture in stationary phase would likely show better survival following exposure to UV radiation compared to the culture in logarithmic phase. This is because stationary phase cells are more likely to have protective mechanisms activated and may be better equipped to handle stressors like UV radiation.
Can bacillus megaterium grow in MSA plates?
yes
Reaction of Bacillus Megaterium in a catalase test?
Bacillus megaterium is catalase-positive, meaning it produces the enzyme catalase which breaks down hydrogen peroxide into water and oxygen. In a catalase test, if Bacillus megaterium is added to hydrogen peroxide, you would observe the formation of bubbles or effervescence due to the release of oxygen gas. This is a positive catalase test result for Bacillus megaterium.
What is the difference between B. subtilis and B. megaterium?
Bacillus subtilis and Bacillus megaterium are both Gram-positive, rod-shaped bacteria, but they differ in several key aspects. B. subtilis is commonly used as a model organism in laboratory studies due to its ability to form spores and its genetic tractability, while B. megaterium is known for its larger cell size and ability to produce a variety of enzymes, making it valuable in industrial applications. Additionally, B. subtilis typically has a faster growth rate compared to B. megaterium. Their ecological roles and metabolic capabilities also vary, with B. megaterium being more versatile in degrading complex substrates.
What is an anarobe cell?
Don't need no oxygen
What is a synonym for discretionary?

This is because stationary phase cells are more likely to have protective mechanisms activated and may be better equipped to handle stressors like UV radiation.
What it means by faculative organism?
is salmonella typhi a gram negative bacteria or coccobacilli
Is bacillus megaterium harmful to humans?
no it is not harmful to us
Can bacillus megaterium grow in MSA plates?
yes
Which bacteria does the curing of tea leaves?
Bacillus megaterium

This is a positive catalase test result for Bacillus megaterium.
What is the endospore position for Bacillus megaterium?
Bacillus megaterium forms central endospores, which are located in the center of the bacterial cell. These endospores are highly resistant structures that allow the bacterium to survive in harsh conditions.
