Microbiology is the study of microorganisms, including unicellular (single-celled) eukaryotes and prokaryotes, fungi, and viruses. Today, most of the work in microbiology is done using methods from biochemistry and genetics. It is also related to pathology, as many microorganisms are pathogens. Microbiologists have made many fundamental contributions to biology, especially in the fields of biochemistry, genetics, and cell biology. Microbes have many traits that make them ideal model organisms Pure yeast cultures are grown in a medium of sugars, nitrogen sources, minerals, and water. The final product may take the form of dried yeast cells, or the yeast may be pressed into cakes with some starchy material. When a batch of yeast for baking, medicinal, or food purposes is completed, the medium in which the yeast was grown is discarded. In the making of wines, beers, spirits, and industrial alcohol, however, the fermented medium is the desired product, and the yeast itself is discarded or used to make animal feed.

These photosynthetic bacteria paved the way for today's algae and plants. Cyanobacteria grow in the water, where they produce much of the oxygen that we breathe. Once considered a form of algae, they are also known as blue-green algae. The human body consists of millions of different cells. A bacterium consists of a single cell. A bacterium’s genetic information is contained in a single DNA molecule suspended in a jelly-like substance called cytoplasm. In most cases, this and other cell parts are surrounded by a flexible membrane that is itself surrounded by a tough, rigid cell wall. A few species, such as the mycoplasmas, don’t have cell walls. In 1973, a Dallas resident went out to the backyard only to stumble upon a reddish, jelly-like mass pulsating in the grass. News reports on the discovery claimed that a new life form had been found, and many people couldn’t help recalling the cult classic sci-fi thriller The Blob. Scientists called to the scene, however, put any fears of menacing goo or alien creatures to rest by identifying the mass as an unusually large (46 centimeters or more than 14 inches in diameter) plasmodial slime mold.
