Isolated thunderstorms are when there are either thunderstorms present at the current time or there is a change for them to form, but they are scattered. These usually occur in the afternoon and the evening when the sun is out at its peak and heats up the atmoshpere.
For example, bacteria from the genus Salmonella are mostly facultative anaerobes, oxidase-negative, catalase-positive and gramnegative rods. Most strains are motile and ferment glucose with production of both acid and gas.
Hydrogen peroxide isn't antibacterial. Many bacteria produce the enzyme catalase which breaks down H2O2 into oxygen and water. The reason it foams is due to the release of oxygen bubbles. Your red blood cells and the fluid between your tissues also contain catalase. So, a sterile cut will still bubble.
