The characterized 10 Streptomyces isolates were previously selected by their abilities to solubilize phosphates. To investigate whether these represent multifaceted plant growth-promoting rhizobacteria (PGPR), potassium-solubilizing, auxin-producing and inhibitory activities determined. spp. yielded a variable biomass in the presence of insoluble orthoclase as sole potassium (K) source, indicating that they able extract different amounts K from this source for own growth. Three strains (AZ,...
A phosphate mine from Togo, an original biotope rich in insoluble rock (RP), was explored for the presence of RP solubilizing actinobacteria. One hundred and fifty actinobacteria isolates originating this tested their ability to grow on a synthetic minimum medium (SMM) containing as unique source. Only 29 (19%) were able weather SMM medium. Five showed most active growth solubilization capability. These shown be solubilize liquid cultures. The study mechanisms involved these weathering...
In the course of our research, aimed at improving sugar beets phosphorus nutrition, we isolated and characterized Streptomyces sp. strains, endemic from beet fields Beni-Mellal region, which are able to use natural rock phosphate (RP) tricalcium (TCP) as sole sources. Ten isolates yielded a comparable biomass in presence these two insoluble sources, indicating that they were extract similar amount (P) latter for their own growth. Interestingly, five strains released soluble P large excess...
A novel actinomycete, strain X4 T , was isolated from a phosphate mine in Youssoufia, 100 km north of Marrakesh, Morocco. The taxonomic status this evaluated by polyphasic approach. Strain had white aerial mycelium with Rectiflexibiles spore chains bearing smooth-surfaced spores and did not produce diffusible pigments. Chemotaxonomic analysis showed that the cell wall contained ll -diaminopimelic acid glycine. Phylogenetic based on almost complete 16S rRNA gene sequence indicated belongs to...
Soil actinomycetes explorations appear to be an efficient alternative as biofertilizers optimize the use of phosphorus (P) resources and enhance plant growth. This research aimed explore distribution isolated from four different rhizospheric Moroccan oat soils investigate their potential for P solubilization. The was significantly more abundant in Settat (9.68%), Tangier (7.38%), Beni Mellal (6.87%) than Merchouch-Rabat (4.90%) region. A total 235 actinomycete strains were all sites tested...
Some soil-borne microorganisms are known to have the ability solubilize insoluble rock phosphate and this process often involves excretion of organic acids. In issue, we describe characterization a novel solubilizing mechanism used by Streptomyces strain related griseus isolated from Moroccan mines. This compound belonging viridomycin family that was shown play major role in bio weathering process. We propose chelation positively charged counter ions constitutive molecule leads...
Traditional antimicrobial antibiotics are increasingly suffering from the emergence of multidrug resistance among pathogenic microorganisms. The antibiotic era is threatened by ruthless rise in bacterial infections. A significant role these profiles attributed to efflux pumps. Hence, much effort being directed towards developing new compounds overcome this problem. During our screening program pumps inhibitors (EPI) produced bioactive Moroccan Actinobacteria, 210 isolates were screened for...
Abstract Euphorbia resinifera O. Berg is a prickly, leafless and succulent, Moroccan endemic shrub. Field data indicate that the plant faces many challenges related to its natural regeneration gradual decline can lead probability of extinction, at least in some areas. Successful seed germination survival E. seedlings during dry period one main obstacles encountered establishing seedlings. With this mind, 3080 seeds two morphotypes (M1 M2) were harvested Atlas Beni Mellal study their...
