  1. g soil micro-flora have gained the greatest importance in recent years as producers of therapeutic substances. Many of the Actinomycetes have the ability to synthesize metabolites which hinder the growth of bacteria; these are called antibiotics, and, although harmful to bacteria.
  2. 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. The actinomycetes produce an enormous variety of bioactive molecules, e.g., antimicrobial compounds. One of the first antibiotics used is streptomycin produced by Streptomycin griseus . On the whole, the last 55 years have seen the discovery of more than 12,000 antibiotics. The actinomycetes yielded about 70 % o 1. Introduction. The word Actinomycetes is derived from Greek word atkis (a ray) and mykes (fungus), having characteristics of both bacteria and fungi but yet possess sufficient distinctive features to delimit them into kingdom bacteria. Actinomycetes are aerobic spore forming gram-positive bacteria; containing high guanine-cytosine (57-75%) in their genome, and belong to.

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.. The cell wall and the internal structure of the actinomycetes are. 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

ADVERTISEMENTS: Actinomycetes are classified into 7 families. The classification is based on hyphal and reproductive structures. Family 1: Streptomycetaceae: ADVERTISEMENTS: Hyphae non-fragmented, aerial mycelium with chains of spores with 5 to 50 or more conidia per chain e.g. Streptomyces, Microdlobaspone and Sporictilhya. Family 2: Nocardiaceae: Hyphae typically fragmented e.g. Nocardia. Actinomycetes are aerobic, spore forming gram-positive bacteria, belongin g to the. order Actinomycetales characterized with subs trate and aerial mycelium growth. It ha s a high. (G+C) ratio of. Actinomycetes Actinomycetes are best known for their ability to produce antibiotics and are gram positive bacteria which comprise a group of branching unicellular microorganisms. They produce branching mycelium which may be of two kinds viz., substrate mycelium and aerial mycelium. Among actinomycetes, the streptomycetes are the dominant Actinomycetes are called actinobacteria or high G + C rich Gram-positive filamentous bacteria due to their mycelium like (slender and branched) structures. These filaments are long and it may fragment into much smaller units and less broad than that of the fungal mycelium usually 0.5 to 1.0 µm in diameter but sometimes reaches to 2.0 µm in. 1993). Several endophytic actinomycetes act as plant growth promoter by producing of phytohormone, indole-3- acetic acid, iron chelating molecules and siderophores (Indananda et al., 2011) Discovery of novel microbial metabolites from actinomycetes can be enhanced by isolating diverse group of actinomycetes

Actinomycetes are Gram-positive, facultative anaerobic fungus-like filamentous bacteria which remain on the top of the natural antibiotic producers. Due to the climatic and geographical diversity of Nepal, a wide range of microorganisms with potent source of antimicrobials are available. The objective of this study was to isolate, identify, and screen the potential antimicrobial-producing. Actinomycetes (branching bacteria ): Dr.Jawad K. Al-Khafaji-----Actinomycete (fungus-like bacteria) resembles fungus as it forms mycelia and resemble bacteria as it has not true nucleus. Important properties: 1. Actinomycetes for many years were classified as fungi because the actinomycetes are form long branching filaments that resemble th The Actinobacteria are a phylum of mostly Gram-positive bacteria.They can be terrestrial or aquatic. They are of great economic importance to humans because agriculture and forests depend on their contributions to soil systems. In soil they help to decompose the organic matter of dead organisms so the molecules can be taken up anew by plants.While this role is also played by fungi. The filamentous bacteria are a normal commensal inhabitant of the oral and buccal cavities, gastrointestinal tract and female genitalia. The etiology of infection in skin is commonly linked with a traumatic injury, human bite or a perforating injury, which creates an anaerobic environment for Actinomyces israelii to grow in ( J Clin Diagn Res.

Endophytic actinomycetes act as a promising resource of biotechnologically valuable bioactive compounds and secondary metabolites. Endophytic Streptomyces sp. produced some novel antibiotics which are effective against multi-drug-resistant bacteria Antimicrobial agents produced by endophytes are eco-friendly, toxic to pathogens and do not harm. Microbes in Industrial Products. These microbes play a crucial role in the fermentation process to obtain a number of products. The two common products obtained by fermentation process through industrial processes are fermented beverages, malted cereals, broths, fruit juices, antibiotics, etc Literature surveys, taxonomical differences, and bioassay results have been utilized in the discovery of new natural products to aid in Actinomycetes isolate-selection. However, no or less investigation have been done on establishing the differences in metabolomic profiles of the isolated microorganisms. The study aims to utilise bioassay- and metabolomics-guided tools that included.
