"The discovery of antimicrobial substances from Streptomyces
sp.myrophorea will help in our search for new drugs to treat multi-resistant bacteria, the cause of many dangerous and lethal infections.
(24) These isolates belong to genera Streptomyces
, Micromonospora, Actinomadura, Saccharomonospora, and Thermoactinomyces.
The enzyme activity under normal quantitative assay conditions for amylase from Streptomyces
mutabilis was (1.96 U/ml/min), for cellulase from Streptomyces
ghanaensis was (6.1U/ml/min), for L-asparaginase from Enterobacter cloacae was (5U/ml/min), for esterase from Streptomyces
ghanaensis was (38.46U/ml/min), and for caseinase from Streptomyces
rochei was (73.33U/ml/min).
Cho, (2002).Conducive environment and ecology of common scab (Streptomyces
scabies) of potato.
Taking this scenario in consideration, the potential secondary metabolites from Streptomyces
can be experimentally checked as anti-caries agent.
Los medios de cultivo empleados para el aislamiento fueron: ISP2 (International Streptomyces
Project) y AIA: Actinomycete Isolation Agar de Sigma-Aldrich[TM], con Cicloheximida de Sigma-Aldrich[TM] a 0.05 [micron]g [L.sup.-1].
Esto podria deberse a la capacidad de esporular del genero Streptomyces
en el caso de las semillas sin peletizar y su habilidad de consumir nutrientes en el caso de las semillas peletizadas (McCormick & Flardh, 2012).
Conversely, in the agricultural soil, most of the PGPR belonged to the Phylum Firmicutes (50%; n = 22), and Bacillus was the largest genus isolated, followed by Streptomyces
. Regarding the origin of the isolates, the three PF samples contributed similarly to the isolation; however, in the AG samples, most of the isolates were obtained from the AG1, and AG3 only contributed to two isolates.
Asimismo, los microcultivos permitieron observar filamentos delgados con gran cantidad de esporas individuales tipicos de Streptomyces
. Finalmente, las microfotografias de dos cepas seleccionadas [M11-116d (B) y M10-77] permitieron observar hifas muy ramificadas, aunque con escasas esporas (Figura 1).
Considering the advantages of biosurfactants produced by microorganisms, the aim of this paper was to perform the production and the characterization of a new biosurfactant produced by Streptomyces
There are two species of Actinomycetes which have been isolated and known to have a good bioactive activity, namely, Frankia sp and Streptomyces
also observed an inhibition effect of phosphate on biosynthesis of turimycin, the secondary metabolite of Streptomyces
