How do bacteria transfer DNA?
However, many bacterial species can transfer DNA between individual cells by a horizontal gene transfer process referred to as natural transformation. Some species form extraordinarily resilient spores, but for bacteria this is a mechanism for survival, not reproduction.
Why are microbes important?
Microbes are important in human culture and health in many ways, serving to ferment foods and treat sewage, and to produce fuel, enzymes, and other bioactive compounds. Microbes are essential tools in biology as model organisms and have been put to use in biological warfare and bioterrorism.

Who discovered the microorganism?
Microorganisms were first discovered by two remarkable geniuses, Robert Hooke andAntoni van Leeuwenhoek, between 1665 and ca. 1678. They came from very differentbackgrounds and their life histories as scientists converged through a complex series ofevents. Serendipity was at work, and the possibility of their interactions could not havebeen predicted or imagined. The common element that led to their discoveries ofmicroorganisms was the making and use of microscopes, which they approached in
When were microorganisms discovered?
The existence of microscopic organisms was discovered during the period 1665–83 bytwo Fellows of The Royal Society, Robert Hooke and Antoni van Leeuwenhoek. InMicrographia(1665), Hooke presented the first published depiction of a microrganism,the microfungus Mucor. Later, Leeuwenhoek observed and described microscopic pro-tozoa and bacteria. These important revelations were made possible by the ingenuity ofHooke and Leeuwenhoek in fabricating and using simple microscopes that magnifiedobjects from about 25-fold to 250-fold. After a lapse of more than 150 years, microscopybecame the backbone of our understanding of the roles of microbes in the causation ofinfectious diseases and the recycling of chemical elements in the biosphere.
Did Leeuwenhoek see bacteria?
We thus come to the remarkable conclusion that, beyond doubt, Leeuwenhoek in his experimentwith the fully closed tube had cultivated and seen genuine anaerobic bacteria, which would hap-pen again only after 200 years, namely about 1862 by Pasteur. That Leeuwenhoek, one hundredyears before the discovery of oxygen and the composition of air, was not aware of the meaningof his observations is understandable. But the fact that in the closed tube he observed an increasedgas pressure caused by fermentative bacteria and in addition saw the bacteria, prove in any casethat he not only was a good observer, but also was able to design an experiment from which aconclusion could be drawn.
Overview
A microorganism, or microbe, is an organism of microscopic size, which may exist in its single-celled form or as a colony of cells.
The possible existence of unseen microbial life was suspected from ancient times, such as in Jain scriptures from sixth century BC India. The scientific study of microorganisms began with their observation under the microscope in the 1670s by Anton van Leeuwenhoek. In the 1850s, Louis P…
Discovery
The possible existence of microscopic organisms was discussed for many centuries before their discovery in the seventeenth century. By the sixth century BC, the Jains of present-day India postulated the existence of tiny organisms called nigodas. These nigodas are said to be born in clusters; they live everywhere, including the bodies of plants, animals, and people; and their life lasts only for a fraction of a second. According to the Jain leader Mahavira, the humans destroy …
Classification and structure
Microorganisms can be found almost anywhere on Earth. Bacteria and archaea are almost always microscopic, while a number of eukaryotes are also microscopic, including most protists, some fungi, as well as some micro-animals and plants. Viruses are generally regarded as not living and therefore not considered as microorganisms, although a subfield of microbiology is virology, the study of viruses.
Ecology
Microorganisms are found in almost every habitat present in nature, including hostile environments such as the North and South poles, deserts, geysers, and rocks. They also include all the marine microorganisms of the oceans and deep sea. Some types of microorganisms have adapted to extreme environments and sustained colonies; these organisms are known as extremophiles. Extremophiles have been isolated from rocks as much as 7 kilometres below the Earth's surface…
Applications
Microorganisms are useful in producing foods, treating waste water, creating biofuels and a wide range of chemicals and enzymes. They are invaluable in research as model organisms. They have been weaponised and sometimes used in warfare and bioterrorism. They are vital to agriculture through their roles in maintaining soil fertility and in decomposing organic matter.
Microorganisms are used in a fermentation process to make yoghurt, cheese, curd, kefir, ayran, xyn…
Human health
Microorganisms can form an endosymbiotic relationship with other, larger organisms. For example, microbial symbiosis plays a crucial role in the immune system. The microorganisms that make up the gut flora in the gastrointestinal tract contribute to gut immunity, synthesize vitamins such as folic acid and biotin, and ferment complex indigestible carbohydrates. Some microorganisms that are seen to be beneficial to health are termed probiotics and are available as dietary …
In fiction
