can eubacteria live in extreme environments?

They can easily survive in such extreme environment as sea vents releasing sulfide-rich gases, hot springs, or boiling mud around volcanoes. They are found in the depths of the ocean. They are found in these place also swamps, deep-sea waters, sewage treatment facilities, and even in the stomachs of cows.

Like archeans, eubacteria are prokaryotes, meaning their cells do not have nuclei in which their DNA is stored. ... Eubacteria are enclosed by a cell wall. The wall is made of cross-linked chains of peptidoglycan, a polymer that combines both amino acid and sugar chains.

Whereas essentially all eukaryotic organisms require oxygen to thrive, many species of bacteria can grow under anaerobic conditions. Bacteria that require oxygen to grow are called obligate aerobic bacteria.

Endospores can survive without nutrients. ... A variety of different microorganisms form "spores" or "cysts", but the endospores of low G+C gram-positive bacteria are by far the most resistant to harsh conditions. Some classes of bacteria can turn into exospores, also known as microbial cysts, instead of endospores.

There are two kingdoms of prokaryotes. These are the bacteria (or eubacteria ) and the archaebacteria (or the Archaea ). ... It is these differences that have resulted in the microorganisms being grouped into separate kingdoms. For example, eubacteria contain the rigid, stress-bearing network known as the peptidoglycan .

Extremophiles can be found in environments with high salinity, such as the Great Salt Lake, or with low temperatures, such as the Antarctic. b. Extremophiles can include members of the Bacteria or Archaea that live in extreme environments. ... Extremophiles are generally pathogenic to humans.

Recent studies have suggested a link between increasing temperatures due to climate change, and the spread of AMR. Research conducted in Europe, with results published this year, reported antibiotic-resistant bacteria were more likely to be found at warmer times of the year.

To their surprise they discovered unicellular (one cell) organisms in the samples. These organisms are today classified in the kingdom, Archaebacteria. Archaebacteria are found in extreme environments such as hot boiling water and thermal vents under conditions with no oxygen or highly acid environments.

Life at the Far Frontier: Why Are Deep Sea Creatures So Weird? Down at the ocean floor, the environment is not hospitable. It is cold, except near thermal vents. In addition, it is so dark that no plants can live there, and the weight of the water far exceeds anything human bodies can handle.

Although these two types of bacteria are extremely small, the differences are very significant: eubacteria is very ubiquitous these days and can be found everywhere, while archaebacteria can only be found in certain conditions.

Eubacterium. ... Eubacterium, plural eubacteria, also called bacteria, term formerly used to describe and differentiate any of a group of prokaryotic true bacteria from the archaebacteria. Today, true bacteria form the domain Bacteria.

The most primitive bacteria extant today are theromophiles, leading to the consensus view that life arose under extreme conditions. Within and between these extremes, bacteria are found in marine, aquatic, terrestrial and subterranean environments.

In contrast to a eukaryotic cell, there is not a functional segregation inside bacteria . The cytoplasm houses all the chemicals and components that are used to sustain the life of a bacterium, with the exception of those components that reside in the membrane(s), and in the periplasm of Gram-negative bacteria.

Unlike eukaryotic cells, which divide by mitosis or meiosis, eubacteria reproduce by binary fission. In this process, the genetic material is replicated, and the two copies move to separate nucleoid regions. Next, the plasma membrane pinches inward, producing two equal daughter cells.

The new domain names are Bacteria, Archaea and Eukarya, where Eukarya consists of organisms whose cells have a nucleus. ... Unique archaea characteristics include their ability to live in extremely hot or chemically aggressive environments, and they can be found across the Earth, wherever bacteria survive.

Extremophile, an organism that is tolerant to environmental extremes and that has evolved to grow optimally under one or more of these extreme conditions, hence the suffix phile, meaning “one who loves.” Extremophilic organisms are primarily prokaryotic (archaea and bacteria), with few eukaryotic examples.
