Actinomycetes

Actinomycete, (order Actinomycetales), any member of a heterogeneous group of gram-positive, generally anaerobic bacteria noted for a filamentous and branching growth pattern that results, in most forms, in an extensive colony, or mycelium. The mycelium in some species may break apart to form rod Actinomycetes: (Streptomycetes, ray fungi), a group of microorganisms combining the traits of bacteria and fungi. The actinomycetes are characterized by a filamentous or rod-and-coccus structure and the presence of lateral protuberances. They are all gram-positive. The actinomycetes include Actinomyces itself, which forms spores on sporophores Actinomycetes are unicellular, Gram-positive bacteria that belong to the Order Actinomycetales. Members of this group are widely distributed in nature and can be found in a variety of habitats across the world. They have been shown to share a number of characteristics with fungi (e.g. mycelial growth) and cause the same disease as fungi in the eye actinomycetes. The metabolic perspective of actinomycetes not only provides an eresting area for research but also offers the possibility of commercialization of the metabolites generated in the process. Enzymes such as amylase, lipase, and cellulases produced from actinomycetes play an important role in food Actinomycetes. These are the non-motile filamentous structures that are gram-positive in nature that belong to the genus actinobacteria. The group of microorganisms includes single-celled organisms and complex multicellular organisms. These are prokaryotic organisms. These are eukaryotic organisms

Actinomycetes. Actinomycetes belong to the group of prokaryotic, gram-positive bacteria those are having a filamentous structure. Its filamentous structure resembles the fungal mycelium, which consists of a highly dense and filamentous network. Due to the filamentous structure of actinomycetes, it is also termed as thread or ray bacteria Actinomycetes are aerobic, spore forming gram-positive bacteria, belonging to the order actinomycetales characterized with substrate and aerial mycelium growth.

The Actinomycetales are an order of Actinobacteria.A member of the order is often called an actinomycete.Actinomycetales are generally gram-positive and anaerobic and have mycelia in a filamentous and branching growth pattern In this section, we shall discuss three genera of actinomycetes: Actinomyces, Nocardia, and Streptomyces. These organisms have been shown to be higher bacteria, but they were thought to be fungi for many years because they have filamentous forms, 0.5 to 0.8 microns in diameter, which appear to branch (figure 1)

Actinomycetes. A heterogeneous collection of bacteria that form branching filaments. The actinomycetes encompass two different groups of filamentous bacteria: the actinomycetes per se and the nocardia/streptomycete complex. Historically, the actinomycetes were called the ray fungi and were thought to be related to the true fungi, such as bread. Actinomycetes belonging to this cell wall type are further classified on the basis of presence or absence of mycolic acids and further on the basis of molecular weights of the mycolates. 7,8 All these three genera contain medium nocardomycolates (34-60 carbon atoms), as compared to the small corynomycolates (22-38 carbon atoms) or the large.

Actinomycetes - Definition, Classification/Characteristics

Actinomycetes, a Gram positive bacteria, well reported as a source of antibiotics, also possess potential to control various plant pathogens, besides acting as plant growth promoting agent. Chemicals in different forms are extensively being used in vegetable farming, adversely affecting the environment and consumer health. Microbial agent like actinomycetes can substantially replace these. The marine environment represents a largely untapped source for isolation of new microorganisms with potential to produce biologically active secondary metabolites. Among such microorganisms, Gram-positive actinomycete bacteria are of special interest,.

Nitrogen-fixing actinomycetes, Frankia produces true mycelium, and they are microaerophilic and live symbiotically with non-leguminous plants. The characteristics of some important genera are given below. Micrococcus, is a non-motile, Gram-positive cocci, aerobic with a high DNA base composi­tion (66 to 72 mol % G + C). It is generally found. Actinomycetes also help in nutrient cycling and degradation of complex organic matters in the soil into simpler forms and play important role in the bio-geo cycles and help maintain equilibrium in the soil environment. Thus they also play a crucial role in maintaining a healthy ecosystem. One more desirable trait in this group of bacteria is. Actinomycetes are actinobacteria are a group of Gram-positive bacteria with high guanine and cytosine content. They can be terrestrial or aquatic. Actinobacteria is one of the dominant phyla of. Actinomycetes is the correct name if this class is regarded as a separate class (i.e., if its nomenclatural type is not assigned to another class whose name is validly published, legitimate and not rejected and has priority). According to Tindall (2014) the type order is Actinomycetales Buchanan 1917
