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

  • Fungi strengthen plants to fend off aphids
    on January 22, 2021 at 4:22 pm

    Researchers have demonstrated that unique fungi strengthen the 'immune systems' of wheat and bean plants against aphids. Fungi enter and influence the amount of a plant's own defenses, resulting in fewer aphids. The results could serve to reduce agricultural insecticide use.

    With an epitope-based immunization, scientists have described a new vaccination strategy against Staphylococcus aureus.

  • Beetles reveal how to hide the body
    on January 21, 2021 at 6:20 pm

    A corpse is a home to the burying beetle, and researchers are learning how this specialist critter keeps its home free of unwanted visitors.

    Researchers describe the effects of antibiotics on membrane vesicles, demonstrating that such drugs actively modify the properties of vesicle transport. Under the influence of antibiotics, MVs were produced and released by bacteria in greater abundance and traveled faster and further from their origin. The work sheds new light on these important information-carrying entities, implicated in many cellular communication processes, including antibiotic resistance.

    on January 21, 2021 at 6:18 pm

    Understanding the genetic and environmental factors that enable some feral honey bee colonies to tolerate pathogens and survive the winter in the absence of beekeeping management may help lead to breeding stocks that would enhance survival of managed colonies, according to a study.

    on January 22, 2021 at 3:55 pm

    Metagenomics—the study of genetic material from an environmental sample—is growing as species evolve or are discovered across the globe. To correlate the newly developed microbiomes with existing data sets, a team of researchers based in China has developed the Microbiome Search Engine 2 (MSE 2). It was published on Jan. 19 in mSystems, a journal of the American Society for Microbiology.

  • A new way to forecast beach water quality
    on January 22, 2021 at 1:44 pm

    Less than two days of water quality sampling at local beaches may be all that's needed to reduce illnesses among millions of beachgoers every year due to contaminated water, according to new Stanford research. The study, published in Environmental Science & Technology, presents a modeling framework that dependably predicts water quality at beaches after only a day or two of frequent water sampling. The approach, tested in California, could be used to keep tabs on otherwise unmonitored […]

    on January 21, 2021 at 5:47 pm

    Scientists have been pondering if the microbiome of plants is due to nature or nurture. Research at Stockholm University, published in Environmental Microbiology, showed that oak acorns contain a large diversity of microbes, and that oak seedlings inherit their microbiome from these acorns.

    on January 21, 2021 at 12:51 pm

    Yield, purity and integrity, of microbial DNA extracted from digesta samples is crucial for downstream analysis of amplicon sequencing. These markers of quality are influenced by chemical and mechanical lysis. However, contributions of chemical and mechanical lysis have not been investigated in DNA extraction methodology.

    Understanding the genetic and environmental factors that enable some feral honey bee colonies to tolerate pathogens and survive the winter in the absence of beekeeping management may help lead to breeding stocks that would enhance survival of managed colonies, according to a study led by researchers in Penn State's College of Agricultural Sciences.
