actinobacteria
(noun)
A group of Gram-positive bacteria with high guanine and cytosine content in their DNA
Examples of actinobacteria in the following topics:
-
Actinobacteria (High G + C Gram-Positive Bacteria)
- Actinobacteria are a group of Gram-positive bacteria with high guanine and cytosine content in their DNA.
- Actinobacteria are a group of Gram-positive bacteria with high guanine and cytosine content in their DNA.
- Actinobacteria is one of the dominant phyla of the bacteria.
- Analysis of glutamine synthetase sequence has been suggested for phylogenetic analysis of Actinobacteria.
- Of those Actinobacteria not in Actinomycetales, Gardnerella is one of the most researched.
-
Overview of Gram-Positive Bacteria and Actinobacteria
- Actinobacteria are Gram-positive bacteria with high guanine and cytosine content in their DNA and can be terrestrial or aquatic.
- Actinobacteria is one of the dominant phyla of bacteria.
- Actinobacteria are well-known as secondary metabolite producers and are hence of high pharmacological and commercial interest.
- Some types of Actinobacteria are responsible for the peculiar odor emanating from the soil after rain (petrichor), mainly in warmer climates.
- Most Actinobacteria of medical or economic significance are in subclass Actinobacteridae, order Actinomycetales.
-
Damage to Proteins and Nucleic Acids
- Tetracycline is a broad-spectrum polyketide antibiotic produced by the Streptomyces genus of Actinobacteria, indicated for use against many bacterial infections.
-
Antimycobacterial Antibiotics
- Mycobacterium is a genus of Actinobacteria that includes pathogens known to cause serious and infectious disease.
-
Wetland Soils
- Microfauna and Microflora: size range - 1 to 100 micrometres, e.g. yeasts, bacteria (commonly actinobacteria), fungi, protozoa, roundworms, and rotifers.
-
Deinococcus and Thermus
- Several bacteria of comparable radioresistance are now known, including some species of the genus Chroococcidiopsis (phylum cyanobacteria) and some species of Rubrobacter (phylum actinobacteria); among the archaea, the species Thermococcus gammatolerans shows comparable radioresistance.
-
Non-Spore-Forming Firmicutes
- Scientists once classified the Firmicutes to include all Gram-positive bacteria, but have recently defined them to be of a core group of related forms called the low-G+C group, in contrast to the Actinobacteria.
-
Chloroflexus and Relatives
- Whereas most bacteria, in terms of diversity, are diderms and stain Gram negative with the exception of the Firmicutes (low CG Gram positives), Actinobacteria (high CG gram positives), and the Deinococcus-Thermus group (Gram positive, but diderms with thick peptidoglycan), the members of the phylum Chloroflexi are monoderms and stain mostly Gram negative.
-
Microbiota of the Skin
- Most come from four phyla: Actinobacteria (51.8%), Firmicutes (24.4%), Proteobacteria (16.5%), and Bacteroidetes (6.3%).

Firmicutes
- Scientists once classified the Firmicutes to include all Gram-positive bacteria, but have recently defined them to be of a core group of related forms called the low-G+C group, in contrast to the Actinobacteria.
