Encyclopedia

Microorganism, or microbe, is a microscopic organism, which may be single-celled or multicellular. Microorganisms include all unicellular organisms and so are extremely diverse. Of the three domains of life identified by Carl Woese, all of the Archaea and Bacteria are microorganisms. These were previously grouped together in the two domain system as Prokaryotes, the other being the Eukaryotes. The third domain Eukaryota includes all multicellular organisms and many unicellular protists and protozoans. Some protists are related to animals and some to green plants. Many of the multicellular organisms are microscopic, namely micro-animals, some fungi and some algae, but these are not discussed here.

They live in almost every habitat from the poles to the equator, deserts, geysers, rocks and the deep sea. Some are adapted to extremes such as very hot or very cold conditions, others to high pressure and a few such as Deinococcus radiodurans to high radiation environments. Microorganisms also make up the microbiota found in and on all multicellular organisms. A December 2017 report stated that 3.45-billion-year-old Australian rocks once contained microorganisms, the earliest direct evidence of life on Earth. — Wikipedia

Science

Microbiology is the study of microorganisms, those being unicellular (single cell), multicellular (cell colony), or acellular (lacking cells). Microbiology encompasses numerous sub-disciplines including virology, parasitology, mycology and bacteriology.

Eukaryotic microorganisms possess membrane-bound cell organelles and include fungi and protists, whereas prokaryotic organisms—all of which are microorganisms—are conventionally classified as lacking membrane-bound organelles and include eubacteria and archaebacteria. Microbiologists traditionally relied on culture, staining, and microscopy. However, less than 1% of the microorganisms present in common environments can be cultured in isolation using current means.
Microbiologists often rely on molecular biology tools such as DNA sequence based identification, for example 16s rRNA gene sequence used for bacteria identification. — Wikipedia

    Within and upon every human being reside countless microorganisms—the microbiota that help shape and direct the lives of their hosts. A similar phenomenon occurs between people, microbes and the homes they share.

    Antibiotic resistance is a ticking timebomb under public health. The WHO predicts that in 2050 more people will die from infections than from cancer—and we are talking about infections that we today consider harmless; infections that occur in a cut or wound—or perhaps cystitis.

    The oceans are teeming with countless forms of life, from the world's largest creature—the blue whale—to miniscule microorganisms. In addition to their vast numbers, these microorganisms are also crucial for ensuring that the entire eco- and climate system work properly. For instance, there are photosynthetically active varieties such as cyanobacteria that produce around 50 percent of the oxygen in the atmosphere. Moreover, by removing carbon dioxide from the atmosphere, microorganisms help […]

    Assembly of HIV-1, which causes AIDS, takes place on the inner plasma membrane leaflet of infected cells, a geometric building process that creates hexamers out of trimers of the viral Gag protein, as guided by Gag's N-terminal matrix domain.

    In the context of climate change, the phenomenon of oxygen-depleted areas in the ocean has become a focus of scientific attention in recent years. These areas, known as oxygen minimum zones (OMZ), are located in the Indian Ocean or off the Peruvian coast in the Pacific, for example. Depending on water depth, little or no oxygen is found there.

    Researchers describe the morphological and genomic features of a 'macro' microbe' -- a giant filamentous bacterium composed of a single cell discovered in the mangroves of Guadeloupe. Using various microscopy techniques, the team also observed novel, membrane-bound compartments that contain DNA clusters dubbed 'pepins.'

    Every day, people die of simple inflammation because bacteria can no longer be killed with antibiotics. So what do we do? Maybe we should spend less energy on killing them and more on 'only' making them harmless while they are in our body, researchers suggest.

  • Researchers make virus-fighting face masks
    on June 21, 2022 at 10:45 pm

    Researchers have developed an accessible way to make N95 face masks not only effective barriers to germs, but on-contact germ killers. The antiviral, antibacterial masks can potentially be worn longer, causing less plastic waste as the masks do not need to be replaced as frequently.
