Bacteria
(gcide) | Bacterium \Bac*te"ri*um\ (b[a^]k*t[=e]"r[i^]*[u^]m), n.; pl.
Bacteria (b[a^]k*t[=e]"r[i^]*[.a]). [NL., fr. Gr.
bakth`rion, ba`ktron, a staff: cf. F. bact['e]rie.] (Biol.)
A microscopic single-celled organism having no
distinguishable nucleus, belonging to the kingdom Monera.
Bacteria have varying shapes, usually taking the form of a
jointed rodlike filament, or a small sphere, but also in
certain cases having a branched form. Bacteria are destitute
of chlorophyll, but in those members of the phylum Cyanophyta
(the blue-green algae) other light-absorbing pigments are
present. They are the smallest of microscopic organisms which
have their own metabolic processes carried on within cell
membranes, viruses being smaller but not capable of living
freely. The bacteria are very widely diffused in nature, and
multiply with marvelous rapidity, both by fission and by
spores. Bacteria may require oxygen for their
energy-producing metabolism, and these are called aerobes;
or may multiply in the absence of oxygen, these forms being
anaerobes. Certain species are active agents in
fermentation, while others appear to be the cause of certain
infectious diseases. The branch of science with studies
bacteria is bacteriology, being a division of
microbiology. See Bacillus.

Archaebacteria
(gcide) | Archaebacteria \Ar*ch[ae]"bac*te"ri*a\, Archaeobacteria
\Ar*ch[ae]"o*bac*te"ri*a\, n. (Microbiol.)
A group of single-celled microorganisms including the
methanogens and some halophiles and thermoacidophiles,
recognized in the 1970's by C. R. Woese and his colleagues as
being a distinct group on the basis of RNA sequences, cell
walls, and coenzymes differing from those of other microbes.
It is believed to be an ancient form of living organism that
evolved separately from the eubacteria and blue-green algae.
It is classified as a separate kingdom by some taxonomists.

cyanobacteria
(gcide) | cyanobacterium \cyanobacterium\ pl. cyanobacteria
\cyanobacteria\ [from the pigment phycocyanin.]
any of a group of photosynthetic autotrophic prokaryotic
microorganisms possessing characteristics of both bacteria
and plants. When classed as bacteria, they are assigned to
the Cyanobacteria; when classed as plants, they are assigned
to the Cyanophyta. They were earlier named {blue-green
algae}, a term less used now in technical discussions. Since
the chlorophyll within the cyanobacteria is diffused
throughout the cell, rather than being contained in
chloroplasts, they are no longer thought of as true plants.

are now known to be prokaryotic, and are usually called
cyanobacteria in technical contexts. See cyanobacterium.
