Antibiotics. Antibiotics are any substance which can act to inhibit the growth of, or kill, bacteria. Because of this, they have become vital to humans for combatting bacterial infection and are used to treat everything from bacterial gastroenteritis to bubonic plague. During the “Golden Age” of antibiotic discovery, 70-80% of all ...

We know microorganisms produce antibiotics. In order to survive these organisms naturally bear resistant gene against their own antibiotics. The genes can be transferred between and among microorganisms by genetic exchange. Resistant genes in bacteria to certain antibiotics were found even prior to the discovery of those antibiotics.

Tetracycline, Streptomycin, Daptomycin The discovery that a fungus could naturally produce a bug-killing substance led to the idea that other microbes might do the same. Actinomycetes (also known as Actinobacteria) is a model organism of antibiotic production.

Abstract. Several microorganisms are known to produce a wide variety of antibiotics that are being developed and used against numerous life-threatening infections and diseases in humans, animals, and agriculture. Antibiotics are produced by several groups of microbes such as bacteria, fungi, and actinomycetes as their natural defense system ...

'The Streptomyces bacteria are able to produce the antibiotics we seek, but they will not do this automatically. You have to, as it were, awaken the antibiotics in the bacteria by stimulating them...

The natural antibiotics are among the most important antibiotics used to treat bacterial or fungal infections. Some examples of natural antibiotics are the penicillin (from Penicillium fungi), aminoglycosides such as streptomycin (produced by bacteria of the genus Streptomyces) and antibiotics such as polyaromatic anthracyclines and tetracycline (mainly produced by fungi and also bacteria).

Some antibiotics are produced naturally by fungi. These include the cephalosporin producing Acremonium chrysogenum. Geldanamycin is produced by Streptomyces hygroscopicus. Erythromycin is produced by what was called Streptomyces erythreus and is now known as Saccharopolyspora erythraea.

Microorganisms are the main culprit for the development of infections that can be prevented by the use of antimicrobial agents. Therapeutic efficacy of antimicrobial agents is based on the selectivity of toxicity having capability to kill the invading microorganisms without harming the host cells, but their production and stability are major concerns.
