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

    A team has demonstrated that fermenting drinks fortified with pea and rice proteins yields the same quality of protein as casein, an animal protein found in milk.

  • Plastic, the Trojan Horse
    on July 27, 2021 at 9:17 pm

    A new study has found plastic accumulation in foods may be underestimated. There is also concern these microplastics will carry potentially harmful bacteria such as E. coli, which are commonly found in coastal waters, up the food chain.

    International drilling efforts over the last decades into the seafloor have provided increasing evidence for the existence of an extensive deep biosphere below the seafloor. There, circulating fluids in the sub-seafloor deliver chemical compounds from which energy is produced to fuel microbial life in such deep ecosystems. Our understanding of the role of such chemolithotrophic microbes in the continental deep biosphere, however, is much more limited due to poor accessibility.

  • Genomic secrets of deep-sea tubeworm
    on July 27, 2021 at 6:53 pm

    Researchers have decoded the chromosomal-level genome of a deep-sea gutless tubeworm and the genome of its co-living 'partner' -- a kind of bacteria that provide nutrients they generate from inorganic compounds to the worm for the first time, explaining how the pair adapts to the extreme habitat. Their discovery lays foundation for potential applications such as nutrient generation, biomaterial production and microbial growth control.

    Too much milk gets pitched, something that was an issue long before these pandemic times of global food insecurity. One of every three gallons of milk was estimated to go to waste in America, according to U.S. Department of Agriculture data from the previous decade. A group of scientists, including one now at Washington University in St. Louis, used mathematical models to integrate knowledge from multiple disciplines—milk production and processing, microbiology and supply chain—thereby […]

    Whether summer or winter, midnight sun or polar night—the sand on the ocean floor is always inhabited by the same bacteria. Although the microbial communities differ between different ocean regions, they do not change between the seasons. Presumably, there is simply no room for change. Researchers at the Max Planck Institute for Marine Microbiology in Bremen, Germany, now describe this phenomenon in a study published in the journal ISME Communications.
