Streptomyces

 [strep″to-mi´sēz]
a genus of bacteria, usually soil forms, but occasionally parasitic on plants and animals, and notable as the source of various antibiotics, e.g., the tetracyclines.

Streptomyces

(strep'tō-mī'sēz),
A genus of nonmotile, aerobic, gram-positive bacteria (family Streptomycetaceae) that grow in the form of a many-branched mycelium; conidia are produced in chains on aerial hyphae. These organisms (several hundred species in the genus) are predominantly saprophytic soil forms; some are parasitic on plants or animals; many produce antibiotics. The type species is Streptomyces albus.
[strepto- + G. mykēs, fungus]

streptomyces

(strĕp′tə-mī′sēz)
n. pl. streptomyces
Any of various actinomycetes of the genus Streptomyces, found chiefly in soil and including several species that produce antibiotics.

Strep·to·my·ces

(strep'tō-mī'sēz)
A genus of nonmotile, aerobic, gram-positive bacteria that grow in the form of a much-branched mycelium; conidia are produced in chains on aerial hyphae. These organisms (several hundred species in the genus) are predominantly saprophytic soil forms; some are parasitic on plants or animals; many produce antibiotics. The type species is S. albus.

Streptomyces

a GENUS of Gram-positive BACTERIA (see GRAM'S STAIN in the ACTINOMYCETES group. Streptomyces species are common inhabitants of SOIL, though they are found in a diversity of habitats. They have a mycelial (see MYCELIUM growth form and reproduce by the formation of SPORES at the tips of aerial HYPHAE. They are AEROBES and can use a wide range of organic compounds as CARBON and ENERGY sources. Often they produce EXTRACELLULAR ENZYMES that enable them to utilize various materials such as STARCH, CELLULOSE and CHITIN. They produce more than half of all known ANTIBIOTICS, and certain species are commercially important. The antibiotic STREPTOMYCIN is produced by Streptomyces griseus.

In our study, we were able to detect the frequently isolated genus Streptomyces with a clear antibacterial activity.
The enzyme exhibited optimum L-asparaginase activity at 5%NaCl (4.2 U/ml/min), and the enzyme activity was (0.46 U/ml/min) at 7.5% NaCl under normal assay conditions Esterase from Streptomyces ghanaensis
This study aimed at exploiting potential secondary metabolites of soil Streptomyces against carries originated S.
Los suelos con CaC[O.sub.3] presentaron menor cantidad de aislados que tratamientos testigo a 60 [grados]C y con respecto a los medios de aislamiento, se obtuvo un mayor numero en AIA (disenado para el aislamiento de actinomicetos) que en ISP (disenado para Streptomyces).
In addition, the isolate SspA1IPSC member of the Streptomyces genus, with four PGP traits (IAA, siderophore production, phosphate solubilisation and chitinase activity) was only isolated from the agricultural soil.
Respecto a actinomicetos seleccionados, se lograron identificar como miembros del genero Streptomyces (Figura 3), resultando las cepas B1TG1 y M11 105 como S.
A strain of Streptomyces sp DPUA1559 isolated from lichens of the Amazon region, belonging to the collection of the Departamento de Parasitologia, Universidade Federal do Amazonas (Manaus, AM, Brazil) was used.
They found that most isolates obtained are of the genus Streptomyces and of other species such as Microbispora, Micromonospora, and Nocardiodes.
These data were similar with the results reported by Chen et al., in which they observed that the optimal concentration of MgS[O.sub.4]x7[H.sub.2]O for glucose isomerase production of Streptomyces flavogriseust was 0.1% with the highest enzyme activity (1.93 U/mg protein); either the lower concentration (0.03%) or the higher concentration (0.5%) resulted in a decline of enzyme activity [12].
Neither bacteria identified through Gram staining and biochemical profiling, not even those identified through sequencing of 16S rRNA genes, yielded species with morphological, biochemical or genetic characteristics belonging to characteristic genera or recognized as lithoautotrophic nitrifying bacteria; instead, organisms belonging to the Streptomyces and Pseudomonas genus were isolated, both of which are known to carry out the nitrifying process heterotrophically (Bitton, 2005; Fiencke et al., 2005; Eldor, 2007).
