A novel halophilic actinomycete strain, H23T, was isolated from a Saharan soil sample collected in Djamâa (Oued Righ region), El-Oued province, South Algeria. Strain H23T was identified as a member of the genus Actinopolyspora by a polyphasic approach. Phylogenetic analysis showed that strain H23T had 16S rRNA gene sequence similarities ranging from 97.8 %(More)
A novel halophilic actinomycete, strain H32T, was isolated from a Saharan soil sample collected in El-Oued province, south Algeria. The isolate was characterized by means of polyphasic taxonomy. Optimal growth was determined to occur at 28–32 °C, pH 6.0–7.0 and in the presence of 15–25 % (w/v) NaCl. The strain was observed to produce abundant aerial(More)
A halophilic actinomycete strain designated H19T, was isolated from a Saharan soil in the Bamendil region (Ouargla province, South Algeria) and was characterized taxonomically by using a polyphasic approach. The morphological and chemotaxonomic characteristics of the strain were consistent with those of members of the genus Actinopolyspora, and 16S rRNA(More)
An alkalitolerant actinomycete strain, designated B32T, was isolated from a Saharan soil sample collected from Adrar province (South of Algeria), and then investigated using a polyphasic taxonomic approach. The strain was observed to produce short chains of spores on the dichotomous branched aerial mycelium and formed a fragmented substrate mycelium. The(More)
Three halophilic mycelium-forming actinobacteria, strains H195T, H150 and H151, were isolated from a Saharan soil sample collected from Béni-isguen in the Mzab region (Ghardaïa, South of Algeria) and subjected to a polyphasic taxonomic characterisation. These strains were observed to show an aerial mycelium differentiated into coccoid spore chains and(More)
A halophilic actinomycete strain, designated H27T, was isolated from a soil sample collected from a hypersaline habitat in Djelfa Province (North-Central Algeria), and then investigated using a polyphasic taxonomic approach. The strain was observed to produce poor aerial mycelium, which formed short chains of oval to cylindrical-shaped spores at maturity,(More)
A novel halophilic, filamentous actinomycete, designated H254T, was isolated from a Saharan soil sample collected from Biskra (Northern Sahara), and subjected to a polyphasic taxonomic characterization. The strain is Gram-positive, aerobic, and halophilic, and the optimum NaCl concentration for growth is 15–20 % (w/v). The cell-wall hydrolysate contained(More)
A novel thermophilic filamentous bacterium, designated strain T36T, was isolated from soil sediment sample from a hot spring source collected in Khenchela province, Algeria. Strain T36T was identified as a member of the genus Thermoactinomyces by a polyphasic approach. Strain T36T was observed to form white aerial mycelium and non-coloured to pale yellow(More)
Genista saharae is an indigenous shrub legume that spontaneously grows in the northeastern Algerian Sahara. It is known for efficient dune fixation and soil preservation against desertification, due to its drought tolerance and its contribution to sustainable nitrogen resources implemented by biological N2-fixation. In this study, the root nodule bacteria(More)
A filamentous actinobacterium, designated strain PM3T, was isolated from a Saharan soil sample collected from Béni-Abbès, Béchar (South-West Algeria). A polyphasic taxonomic study was carried out to establish the status of strain PM3T. The isolate was found to have morphological and chemotaxonomical properties associated with members of the genus(More)
