Document Summary
They know it expires because they know when the bacteria will be harmful or too much. Most electronegative we have common in our bodies and within cells. Anaerobes do not use oxygen, some species don"t use oxgen at all they will die because they produce ros (reactive oxygen species h2o2 peroxide). We have mechanisms in our body that can deal with these things. Able to tolerate low levels of o2 and can catalise ros"s. If youre a fermenter you"re an anaerobe you pass your oxygen to different receptors. Nchops = elements that are being used as electron acceptors, all have electronegativity to them. Things that are anaerobic thrive in areas that don"t have too much oxygen. Deep water, bottom of the ocean, the lower guts of mammals. Ultra high temperature completely sterile, kills all bacteria. Strip that changes color 121 degrees, shows that it works. Can freeze your meat, it only slows down bacteria.
