What makes peroxide 'foam up,' when you apply it to a skin-wound, or other, bacteria-laden surface?

Peroxide seems to foam up, whenever it makes contact with an organic material... does it foam up, because it is reacting to/with the organic material, or is it the contact with the bacteria (contained within the organic material) that causes the peroxide to foam?What makes peroxide 'foam up,' when you apply it to a skin-wound, or other, bacteria-laden surface?
Hydrogen peroxide is a dangerous oxidant which is potentially harmful to living tissues. Therefore, many organisms (certainly all of the more complex ones) have enzymes to destroy hydrogen peroxide by catalyzing its favourable decomposition to water and oxygen. When you apply hydrogen peroxide to a wound, it contacts an iron-based enzyme called ';catalase'; in your tissues, and accordingly decomposes. Some bacteria have another, manganese-based enzyme to deal with hydrogen peroxide, so they can cause it to foam as well.What makes peroxide 'foam up,' when you apply it to a skin-wound, or other, bacteria-laden surface?
