Streptomyces
''Streptomyces'' is the largest genus of Actinomycetota and the type genus of the family Streptomycetaceae. Over 500 species of ''Streptomyces'' bacteria have been described. As with the other Actinomycetota, streptomycetes are gram-positive, and have genomes with high GC content. Found predominantly in soil and decaying vegetation, most streptomycetes produce spores, and are noted for their distinct "earthy" odor that results from production of a volatile metabolite, geosmin. Streptomycetes are characterised by a complex secondary metabolism. They produce over two-thirds of the clinically useful antibiotics of natural origin (e.g., neomycin, streptomycin, cypemycin, grisemycin, bottromycins and chloramphenicol). The antibiotic streptomycin takes its name directly from ''Streptomyces''. Streptomycetes are infrequent pathogens, though infections in humans, such as mycetoma, can be caused by '' S. somaliensis'' and '' S. sudanensis'', and in plants can be caused by '' S. cavi ...

Africa
Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With billion people as of , it accounts for about of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, behind Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young population make Afr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deutsche Sammlung Von Mikroorganismen Und Zellkulturen
The Leibniz Institute DSMZ - German Collection of Microorganisms and Cell Cultures GmbH (German: ''Leibniz-Institut DSMZ-Deutsche Sammlung von Mikroorganismen und Zellkulturen GmbH''), located in Braunschweig, is a research infrastructure in the Leibniz Association. Also the DSMZ is the world's most diverse collection of bioresources (status 2021: 75,000 bioresources). These include microorganisms (including more than 32,000 bacterial strains, 690 archaeal strains, 7,000 strains of yeasts and fungi) as well as more than 840 human and animal cell cultures, over 1. 500 plant viruses, over 940 bacteriophages, and 250 plasmids (status 2021). Since 2010, the scientific director of the Leibniz Institute DSMZ has been Jörg Overmann, a microbiologist with a PhD. He holds a professorship in microbiology at the Technical University of Braunschweig. Since August 2018, he has led the institute in a dual leadership with Bettina Fischer as administrative director.

Aminoacylase
In enzymology, an aminoacylase () is an enzyme that catalyzes the chemical reaction : N-acyl-L-amino acid + H2O carboxylate + L-amino acid : Thus, the two substrates of this enzyme are N-acyl-L-amino acid and H2O, whereas its two products are carboxylate and L-amino acid. This enzyme belongs to the family of hydrolases, those acting on carbon-nitrogen bonds other than peptide bonds, specifically in linear amides. The systematic name of this enzyme class is '' N-acyl-L-amino acid amidohydrolase''. Other names in common use include dehydropeptidase II, histozyme, hippuricase, benzamidase, acylase I, hippurase, amido acid deacylase, L-aminoacylase, acylase, aminoacylase I, L-amino-acid acylase, alpha-N-acylaminoacid hydrolase, long acyl amidoacylase, and short acyl amidoacylase. This enzyme participates in urea cycle and metabolism of amino groups. Enzyme structure As of late 2007, two structures have been solved for this class of enzymes, with PDB accession cod ...

Chartreusin
Chartreusin is an antibiotic originally isolated from the bacteria ''Streptomyces Chartreusis.'' The crystalline compound itself has a yellow-green colour, as per its name, and is stable at room temperature for several hours. Chartreusin is chemically related to elsamitrucin, as the two share an aglycone chartarin structure, though they differ in their sugar moieties. Both chartreusin and elsamitrucin were found to have anticancer activity. Biological activity Chartreusin was shown to be effective as an antibiotic against some gram-positive species, as well as mycobacteria. This compound has also displayed anti-cancer activity, particularly against certain melanomas and leukemia in mice. However, this effect could only be observed in-vivo when the antibiotic was administered via intraperitoneal injection. Chartreusin administered by intravenous therapy was ineffective, as the compound would be excreted through the bile. This compound is believed to function by binding directl ...
