Microorganisms is a scientific, peer-reviewed, open access journal of microbiology, published monthly online by MDPI. The Hellenic Society Mikrobiokosmos (MBK), the Spanish Society for Nitrogen Fixation (SEFIN) and the Society for Microbial Ecology and Disease (SOMED) are affiliated with Microorganisms, and their members receive a discount on ...
Microorganisms are extremely diverse, representing most unicellular organisms in all three domains of life: two of the three domains, Archaea and Bacteria, only contain microorganisms.
The major groups of microorganisms—namely bacteria, archaea, fungi (yeasts and molds), algae, protozoa, and viruses—are summarized below. Links to the more detailed articles on each of the major groups are provided.
Microorganisms first appear on earth and inhabit vast majority of habitats like water, soil, radioactive waste, hot springs as well as biosphere of earth crust.
Microorganisms are diverse entities that inhabit various environments, exhibiting a range of interactions with their hosts and surroundings. This article presents a selection of microorganisms, elucidating their characteristics and significance in the broader context of human health and ecology.
The human body contains trillions of microorganisms, with the largest numbers found in the intestines. Scientists are just beginning to discover all the ways these microbes interact with our bodily functions.
Microorganisms differ from each other not only in size, but also in structure, habitat, metabolism, and many other characteristics. While we typically think of microorganisms as being unicellular, there are also many multicellular organisms that are too small to be seen without a microscope.
As microorganisms, particularly bacteria, are found practically everywhere, this means in most cases the reduction of harmful microorganisms to acceptable levels.
Microorganisms are incredibly diverse and include bacteria and fungi as well as archae, protists, plankton and some amoebae. Viruses are not considered to be living organisms but are often considered to be microorganisms because of their extremely small size.
