Bacteria are prokaryotic organisms where the DNA is held in a nucleoid, which is a non membrane-enclosed organelle. Many people think bacteria are strictly harmful to us, but in fact they coexist to aid in many daily tasks such as digest food or keep our gums healthy. Although we cannot see a bacteria cell with the naked eye, it can reproduce rapidly through binary fission. Binary fission is a method of asexual reproduction by the cell dividing in half. After a certain point, an accumulation of bacteria cells becomes visible to humans without a microscope.

Much research has been done on the effect of different temperatures on the growth rate with bacteria long before this experiment. There was a study conducted about Microbial Oxidation of CH4 at different temperatures in landfill cover soils. Gunnar Börjesson and his team observed that different methanotroph populations in the soil could produce different concentrations of O2 and CH4, temperature, pH, and nitrogen sources. Methanotrophs are bacteria that use CH4 to gain energy and carbon.
