Eubacteria

(ū″băk-tēr′ē-ă)
A group of single-celled organisms without a defined cell nucleus or organelles. They contain peptidoglycans in their cell walls. Eubacteria are prokaryotes and include many familiar microorganisms, (e.g., Escherichia, Helicobacter, Legionella, nitrogen-fixing bacteria, Spirochetes, and staphylococci.) In some classification systems the other prokaryotes also include the archaebacteria and cyanobacteria. In other taxonomic systems the archaebacteria are considered to be a separate kingdom or domain.

Eubacteria

one of the three primary groupings (DOMAINS) according to some classifications, based on genetic structures and sequences, though it is more commonly called the BACTERIA. In other classifications it is the name for the ‘true’ bacteria.

The recently discovered non-mevalonate pathway of isoprenoid biosynthesis serves as the unique source of terpenoids in numerous pathogenic eubacteria and in apicoplast-type protozoa, most notably Plasmodium, but is absent in mammalian cells.
However, the effect of PRA-1 on methanogens and eubacteria of rumen microflora was analysed by PCR-DGGE method.

Anaerobes far outnumber aerobes and conventional culture techniques used to enumerate microbial flora have shown that Bacteroides, eubacteria, clostridia, ruminococci, peptococci, peptostreptococci, bifidobacteria and fusobacteria represent the predominant flora in adults (19,20) while facultative anaerobes such as Escherichia, Klebsiella, Proteus, Lactobacillus and enterococci are some members forming the subdominant genera (10).
The seeps nourish a rich community of archaea and eubacteria that rely on chemosynthesis rather than photosynthesis for energy (Fulweiler, 2009).
The Institute for Genomic Research (TIGR) is a not-for-profit research institute with interests in structural, functional and comparative analysis of genomes and gene products in viruses, eubacteria, pathogenic bacteria, archaea, and eukaryotes (plant, animal and human).
Temperature, pH, salinity, hardness, and particulates mediate nickel toxicity to eubacteria, an actinomycete, and yeasts in lake, simulated estuarine, and sea waters.
The Institute for Genomic Research (TIGR) is a not-for-profit research institute founded in 1992 with interests in structural, functional and comparative analysis of genomes and gene products from a wide variety of organisms including viruses, eubacteria (both pathogens and non-pathogens), Archaea (the so-called third domain of life), and eukaryotes (plants, animals, fungi and protists such as the malarial parasite).
As a result, scientists often divide life into bacteria or eubacteria, archaea or archaebacteria, and eukarya.
The topologies of the ML and maximum parsimony (MP) trees were similar, and each method grouped the taxa according to their expected classification within the gram-negative Eubacteria and separated them from the outgroup taxon, Bacillus subtilis, a gram-positive eubacterium.
