\nUse a plate with the grown microorganisms and in an area where there is quite a lot of growth add a few drops of hydrogen peroxide and watch to see if bubbles appear in a few seconds or not.<\/p>\n

Positive catalase: <\/strong>bubbles appear that represent the release of oxygen, which indicates that the bacterium has the catalase enzyme.<\/p>\n

Negative catalase: <\/strong> bubbles do not appear, which means that the bacterium does not have this enzyme.<\/p>\n\n\n\n
