Gordonia terrae is a non-motile Gram positive Actinobacterium in the family Gordoniaceae. The ATCC strain 25594 is G. terrae C-6 and is sequenced. It is a benzothiophen-desulfuring bacterium isolated from oil-contaminated soil of the GuDao Oile filed, China.

Where can I find gordonia Terrae?

Gordonia species are ubiquitous in the envir- onment and often found in soil and water; however, a few are also sporadically associated with human infections in both immunocompromised and immunocompetent indi- viduals (Arenskötter et al., 2004).

Is Gordonia terrae a bacteria?

Although G. terrae is a soil bacterium [1] and can be a potential skin contaminant, in these symptomatic patients and in some patients who have high colony counts, G. terrae was considered causative.

Is gordonia a mycobacterium?

Gordonia is a genus of bacterium in the Actinobacteria, the same lineage that includes Mycobacterium tuberculosis. The genus was named after American bacteriologist Ruth Gordon in 1971 by Tsukamura.

What is gordonia Sputi?

Gordonia sputi is a member of a diverse group of gram-positive, aerobic, catalase-positive, weakly acid fast rod-shaped actinomycetes bacteria.

Is gordonia acid fast?

Gordonia species are Gram-positive, partially acid-alcohol fast, catalase-positive, aerobic, chemoorganotrophic mycolic acid–containing coccobacillary actinomycetes with high G + C contents in their DNA (63–69%).

Do mycobacteria have a cell wall?

The distinguishing feature of mycobacteria, the complex cell wall, is a well-recognized drug target. The cell wall is common to all bacteria, both Gram-positive and Gram-negative, but can have vast differences in terms of the biochemical and structural features.

Where is Rhodococcus Rhodochrous found?

The species, Rhodococcus rhodochrous, is usually isolated from contaminated soil which does not contribute to any pathogenesis [2]. Many strains of Rhodococcus are considered as significant part of the soil microbial community because of their diverse biodegradation mechanisms [1].

Are actinomycetes bacteria?

Actinomycetes. The Actinomycetes are a group of unicellular filamentous bacteria that form a branching network of filaments and produce spores. They have long been recognized as sources of severe earthy-musty tastes and odours in drinking water (Mallevialle and Suffet, 1987).

What is Nocardioform?

Nocardioforms are filamentous, Gram positive actinomycete bacteria that can cause persistent and excessive foaming in activated sludge plants during the summertime.

How do you grow actinomycetes?

It is best to collect the soil samples from pristine area, including primeval forest, saline, alkaline soils, and desert. Soil samples in depth 5–20 cm are collected and put in sterile paper or plastic bag. Actinomycetes are widely distributed in ocean, and a large number of natural products were found from them.

What do actinomycetes do in soil?

They perform the functions like phosphate solubilization, siderophores production, and nitrogen fixation. Furthermore, actinomycetes do not contaminate the environment; instead, they help to maintain the biotic equilibrium of soil by cooperating with nutrients cycling.

Where actinomycetes are found?

Actinomycetes are found in many habitats, such as freshwater, sea- water, cold- and warm-blooded animals, and composts. The soil, however, is their most important habitat. Viable counts of several millions per gram are common, and over 20 genera have been isolated from soil (Table 45-1).

Is Rhodococcus an Actinomycete?

Rhodococcus equi is a soil-dwelling pathogenic actinomycete that causes pulmonary and extrapulmonary pyogranulomatous infections in a variety of animal species and people.

Is Rhodococcus acid-fast?

Rhodococcus equi is an aerobic Gram-positive and acid-fast coccobacillus that may cause cavitary pneumonia in immunocompromised hosts such as HIV-infected patients.

Is Rhodococcus motile?

Rhodococcus is a genus of obligate aerobic, Gram-positive, partially acid-fast, catalase-positive, non-motile, and none-endospore bacteria. The genus Rhodococcus was first introduced by Zopf. This bacterium can be isolated from various sources of the environment and can grow well in non-selective medium.

What is special about mycobacteria?

Mycobacteria are immobile, slow-growing rod-shaped, gram-positive bacteria with high genomic G+C content (61-71%). Due to their special staining characteristics under the microscope, which is mediated by mycolic acid in the cell wall, they are called acid-fast. This is also the reason for the hardiness of mycobacteria.

Is Mycobacterium prokaryotic?

Mycobacterium tuberculosis prokaryotic ubiquitin-like protein-deconjugating enzyme is an unusual aspartate amidase. J Biol Chem.

What is Mycobacterium made of?

The mycobacterial envelope is unique, containing the so-called mycomembrane (MM) composed of very-long chain fatty acids, mycolic acids (MA). Presently, the molecular composition of the MM remains unproven, due to the diversity of methods used for determining its composition.

Can actinomycetes grow on nutrient agar?

The actinomycetes are Gram positive, organisms that tend to grow slowly as branching filaments. Many actinomycetes will grow on the common bacteriological media used in the laboratory, such as nutrient agar, trypticase soy agar, blood agar, and even brain-heart infusion agar.

Why are actinomycetes abundant in the soil?

According to McCarthy and Williams (1992), organic matter, salinity, relative moisture, temperature, pH and vegetation are important factors which control abundance of actinomycetes in soil.

How many actinomycetes are in a gram of soil?

It has been estimated that if you look at one gram of soil you will see the following numbers of organisms--bacteria 10 8-9 , actinomycetes 105-8 , fungi 105-6 , micro-algae 103-6 , protozoa 103-5 , nematodes 101-2 , other invertebrates 103-5 . A square meter of soil may contain 30-300 earthworms.

Where are microorganisms found?

Microbes are tiny living things that are found all around us and are too small to be seen by the naked eye. They live in water, soil, and in the air. The human body is home to millions of these microbes too, also called microorganisms. Some microbes make us sick, others are important for our health.

What is the role of microorganisms in plants growth?

Some of the most important functions of microbes for promoting plant growth and protecting soil health include nitrogen fixation, denitrification, phosphate and sulphate solubilisation, siderophore production, plant growth promotion, immune modulation, pathogen control and signal transduction ( Prakash et al. 2015 ).

What are the effects of microorganisms to farmers?

On the other hand, pathogenic microorganisms present in agricultural soils can have a harmful effect on the crop inducing: i) pathogenicity and disease, ii) resistance to crop control products, iii) poor soil health or reduced fertility, iv) poor crop health or poor yields, and lastly v) crop loss.
