[6], Like other streptomycetes, S. griseus has a high GC content in its genome,[8] with an average of 72.2%. It produces more than 70% of commercially available antibiotics [8]. Interest in the genus Streptomyces for antibiotics came after the discovery of the antibiotic streptomycin in a S. griseus strain in 1943. It is a Gram-positive bacterium with high GC content. In agriculture, metabolites from the Streptomyces are used as growth promotors, agents for plant protection, antiparasitic agents and herbicides . Self-medication and overuse of antibiotics is another important factor that contributes to resistance, reducing the lifetime of the antibiotic, thus causing the constant need for research and development of new antibiotics. Caractéristiques des génomes de Streptomyces. [22][23] Furthermore, the genomic studies have revealed a single strain of S. griseus IFO 13350 has the capacity to produce 34 different secondary metabolites. Gram-positive bacteria of the genus Streptomyces are industrially important microorganisms, producing >70% of commercially important antibiotics. "Classification of Streptomyces griseus (Krainsky 1914) Waksman and Henrici 1948 and related species and the transfer of 'Microstreptospora cinerea' to the genus Streptomyces as, "A multilocus phylogeny of the Streptomyces griseus 16S rRNA gene clade: Use of multilocus sequence analysis for streptomycete systematics", "Elloxazinones a and B, New Aminophenoxazinones from Streptomyces griseus Acta 2871†", "The influence of natural products upon drug discovery (Antiquity to late 1999)", "Presentation Speech: The Nobel Prize in Physiology or Medicine 1952", "Genome Sequence of the Streptomycin-Producing Microorganism Streptomyces griseus IFO 13350", "New Jersey S3190 | 2016-2017 | Regular Session", "New Jersey A4900 | 2016-2017 | Regular Session", "The Nobel Prize in Physiology or Medicine 1952", https://en.wikipedia.org/w/index.php?title=Streptomyces_griseus&oldid=993341775, Wikipedia articles needing page number citations from December 2012, Creative Commons Attribution-ShareAlike License, This page was last edited on 10 December 2020, at 02:49. Chen YH, Wendt-Pienkowski E, Shen B. Besides the obvious antibiotic that S. griseus produces (streptomycin), S. griseus also produces many more antibiotics and useful enzymes. Streptomyces griseus 18-16 is a thermophilic human pathogen that produces antibiotic compounds and was isolated from soil. Unreviewed-Annotation score: -Protein inferred from homology i. Based on the antiSMASH analyses of CDS structure (Figure 4, D and E), which produced results consistent with the ANI results, the conprimycin biosynthesis sequence in strain TFH56 was 99–100% similar to the sequence in strain S4 … Streptomyces species are known to produce various bioactive metabolites that can prevent plant diseases. We review the regulation of antibiotic biosynthesis in S. coelicolor and other, nonmodel streptomycetes in the light of recent studies. [10] The taxonomy of S. griseus and its evolutionarily related strains have been a considerable source of confusion for microbial systematists. The Brazilian Journal of Infectious Diseases, https://doi.org/10.1016/j.bjid.2012.08.014. The drug acts by interfering with the ability of a microorganism to synthesize certain vital proteins. It is a Gram-positive bacterium with high GC content.Along with most other streptomycetes, S. griseus strains are well known producers of antibiotics and other such commercially significant secondary metabolites.
