How To Sample Testing Compost Find out what we see when we look at your Soil samples. Our new image gallery shows examples of what we view through our microscope and gives you an idea of what we're looking for when we analyze your soil sample. The mere presence of these bacteria is nothing to worry about.
Many bacteria can switch metabolic pathways, depending on whether oxygen is present or depleted.
Your nose is a really good, and inexpensive, indicator of whether anaerobic conditions have occurred. In general the products of anaerobic metabolism are harmful to humans, and humans have developed sensitive receptors to warn of these harmful products. It is possible to measure these compounds on GCs and HPLCs, but it's expensive. At the start of the process, reduce the amount of simple sugars present, which will reduce bacterial and yeast growth, and increase chunky materials to increase the ease with which oxygen can diffuse into the material. It doesn't matter if anaerobic organisms are present, as long as they aren't growing.
