Over the last few years, species of the genus Streptomyces
have been used to produce biosurfactants, especially the bacteria of the Actinomycetes group.
Based on the gathered morphological characteristics, the isolates were classified under the genus Streptomyces
In this connection the present work describes the isolation and screening of the strains of actinomycetes especially the members of genus Streptomyces
for antibacterial and antitumor activity from six different habitats of Pakistan.
Covering in turn virulence mechanisms and important bacterial diseases in agriculture, they discuss such aspects as fimbrial and afimbrial adhesins involved in bacterial attachment to surfaces, high-throughput DNA sequencing technology as a tool in understanding plant-pathogen bacteria, Candidatus liberibacter species and related diseases, virulence mechanisms of plant-pathogen Ralstonia species, and mechanisms of pathogenicity and the emergence of new plant-pathogen species in the genus Streptomyces
The isolate was similar to genus Streptomyces
and identified as S.
Cultural and morphological characterization of the three active isolates using a light microscopy showed that they belong to the genus Streptomyces
Among them, three bioactive isolates were selected based on their larvicidal and insecticidal activity and were identified as species belonging to the genus Streptomyces
by analyzing their morphological characteristics (Locci, 1989) and by preliminary physiological testing.
The phylogenetic relations of taxa in the trees constructed from the largely conserved 16S rRNA gene sequences confirmed that the classic phenotypic, and largely morphological, characteristics used for classification schemes for species of the genus Streptomyces
are generally quite useful for species identification and grouping of similar taxa, including spore colour and spore surface ornamentation .
The filamentous soil bacteria belonging to the genus Streptomyces
are rich sources of a high number of bioactive natural products, which were extensively used as pharmaceuticals and agrochemicals [1, 2].
10) The organisms and colonies of the genus Actinomadura resemble those of the genus Streptomyces
They discovered that bacteria of the genus Streptomyces
produce a cocktail of nine different antibiotics and thereby fend off invading pathogens.
A short list of vitally important microbes could include members of the genus Streptomyces
, which produce a wide range of antibiotic compounds; organisms such as Dehalococcoides ethenogenes that can degrade toxic compounds including perchlorinated ethenes (PCEs); and symbiotic organisms such as Rhizobium that can covert inorganic nitrogen to ammonium and provide this product to their plant hosts.
