These formations may have resulted from carcass burial in an anoxic environment with minimal bacteria, thus delaying decomposition.

These include bacteria, fungi, other plants, and animals.

These include alpha-amylase from bacteria, which converts starch to simple sugars, chymosin from bacteria or fungi that clots milk protein for cheese making, and pectinesterase from fungi which improves fruit juice clarity.

These microorganisms including bacteria and the broad range of organisms that form the marine microbial loop, responsible for regulating much of the oceans ' biogeochemistry.

These surviving bacteria will then reproduce again, producing the next generation.

These carbohydrates types can be metabolized by some bacteria and protists.

These structures can fill most of the interior of a cell, giving the membrane a very large surface area and therefore increasing the amount of light that the bacteria can absorb.
