Bacillus megaterium is a facultative anaerobe, meaning it can grow in both the presence and absence of oxygen. This bacterium has the ability to switch between aerobic and anaerobic metabolism depending on the availability of oxygen in its environment.
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.
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.
yes
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.
The molecular weight of Bacillus megaterium will vary depending on the specific proteins, DNA, RNA, and other molecules present in its cellular structure. Generally, the molecular weight of Bacillus megaterium is estimated to be around 5-10 million Daltons.

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.
