Here we present the draft genome sequence of Streptomyces viridochromogenes Tü57. This strain is a producer of avilamycin A, an oligosaccharide antibiotic from the orthosomycin group, which is active against Gram-positive bacteria.

Two new antibiotics, A-218 and K-41, were isolated from strains identified as Streptomyces hygroscopicus. The antibiotics are characterized as polycyclic polyether compounds and are active against gram-positive bacteria.

Scopafungin (U-29,479) is a crystalline, nonpolyenic antimicrobial agent obtained from the culture broth of Streptomyces hygroscopicus var. enhygrus var. nova UC-2397. Scopafungin inhibits, in vitro, a variety of pathogenic fungi, yeasts, and gram-positive bacteria.

The Streptomycetes are gram positive bacteria with a filamentous form that present in a wide variety of soil including composts, water and plants. The most characteristic of Streptomycetes is the ability to produce secondary metabolites such as antibiotics. They produce over two-thirds of the clinically useful antibiotics of natural origin (e.g., neomycin and chloramphenicol. Another characteri...

A total of sixty eight actinomycetes were isolated from near sea shore marine environment locations of Bigeum Island, South West coast of South Korea. The majority of these isolates were assigned to the genus Streptomyces of which one isolate showing broad spectrum of antimicrobial was on the basis of their morphological, physiological and biochemical properties. Phylogenetic analysis of the 16...

  Antibiotics are the best known products of actinomycete. Over 5,000 antibiotics have been identified from the cultures of Gram positive and Gram-negative organisms, and filamentous fungi, but only about 100 antibiotics have commercially been used to treat human, animal and plant diseases. The genus, Streptomycete, is responsible for the formation of more than 60% of known antibiotics. Bacteri...

The actinobacterium strains were isolated from marine samples that collected from South Sinai Sharm ElSheikh, Egypt. These isolates were screened for antimicrobial activities in starch nitrate medium. One of the actinomycete isolates (Askar-SH50) was found to produce a broad spectrum antimicrobial activity. Identification of the most potent isolate was performed according to the cell wall chemo...

Numerous antibiotics have been obtained from the broth culture of streptomyces, however, none of the antibiotics consisting of carbon, hydrogen, chlorine and oxygen has yet been found. A strain recently isolated from the soil produces an antibiotic which inhibits the growth of Gram positive bacteria. This antibiotic is a new one, because it consists of carbon, hydrogen, chlorine and oxygen. The...
