    en.wikipedia.org/wiki/Eubacterium

    Eubacterium is a genus of Gram-positive bacteria in the family Eubacteriaceae. These bacteria are characterised by a rigid cell wall. They may either be motile or nonmotile. If motile, they have a flagellum.

  3. Bacteria - Wikipedia

    The term "bacteria" was traditionally applied to all microscopic, single-cell prokaryotes. However, molecular systematics showed prokaryotic life to consist of two separate domains, originally called Eubacteria and Archaebacteria, but now called Bacteria and Archaea that evolved independently from an ancient common ancestor.

    Em 1977, com o advento das técnicas moleculares, Carl Woese dividiu os procariotas em dois grupos, com base nas sequências "16S" do RRNA, que chamou de Eubacteria e Archaebacteria, [120] mais tarde, renomeados por ele próprio para Bacteria e Archaea. [123]

  8. Nov 18, 2020 · Eubacteria, or “true” bacteria, are single-celled prokaryotic microorganisms that have a range of characteristics and are found in various conditions throughout all parts of the world. All types of bacteria fall under this title, except for archaebacteria.

U baktérií sa nevyskytuje pohlavné rozmnožovanie, namiesto toho sa najčastejšie delia binárne. Baktérie sú najrozšírenejšou skupinou organizmov na svete.

    Like archeans, eubacteria are prokaryotes, meaning their cells do not have nuclei in which their DNA is stored. This distinguishes both groups from the eukaryotes, whose DNA is contained in a nucleus. Despite this structural resemblance, the Eubacteria are not closely related to the Archaea, as shown by analysis of their RNA (see below).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. Th...

    Despite the lack of internal compartmentalization, bacterial metabolism is complex, and is far more diverse than eukaryotic metabolism. Within the Eubacteria there are species that perform virtually every biochemical reaction known (and much bacterial chemistry remains to be discovered). Most of the vitamins humans require in our diet can be synthesized by bacteria, including the vitamin K humans absorb from the Escherichia coli (E. coli ) bacteria in our large intestines.The broadest and mos...

    Most eubacteria have DNA that is present in a single large circular chromosome. In addition, there may be numerous much smaller circles, called plasmids . Plasmids usually carry one or a few genes. These often are for specialized functions, such as metabolism of a particular nutrient or antibiotic.Despite the absence of a nucleus, the chromosome is usually confined to a small region of the cell, called the nucleoid , and is attached to the innermembrane. The bacterial genome is smaller than t...

    While bacteria do not have sex like multicellular organisms, there are several processes by which they obtain new genes: conjugation , transformation, and transduction. Conjugation can occur between two appropriate bacterial strains when one (or both) extends hairlike projections called pili to contact the other. The chromosome, or part of one, may be transferred from one bacterium to the other. In addition, plasmids can be exchanged through these pili. Some bacteria can take up DNA from the...

    Gene expression in many bacteria is regulated through the existence of operons. An operon is a cluster of genes whose protein products have related functions. For instance, the lac operon includes one gene that transports lactose sugar into the cell and another that breaks it into two parts. These genes are under the control of the same promoter , and so are transcribed and translated into protein at the same time. RNA polymerase can only reach the promoter if a repressor is not blocking it;...
