Abstract In an effort to develop local productions of aromatic and medicinal plants, a comprehensive assessment the composition biological activities essential oils (EOs) extracted from aerial flowering parts wild growing Lavandula stoechas L. collected eleven different locations in northern Algeria was performed. The were characterized by GC‐FID GC/MS analyses, 121 compounds identified, accounting for 69.88–91.2% total oil compositions. greatly differed their compositions, since only 66...
Sixteen endophytic actinobacteria isolated from roots of native plants were evaluated for their antagonistic potential against soil-borne phytopathogenic fungi. Among them, three strong isolates selected and characterised in vitro plant-growth-promoting biocontrol traits, including production hydrogen cyanide, indole-3-acetic acid siderophores, chitinase β-1,3-glucanase activities, inorganic phosphate solubilisation. In all trials, the strain Streptomyces sp. SNL2 revealed promising...
In this study, the biocontrol ability and colonization behavior of a highly antagonistic Streptomyces mutabilis strain, named IA1, recently isolated from Saharan soil, were assessed on wheat seedlings. study we showed that strain IA1 secretes IAA GA3 is able to enhance growth Using DOPE-FISH coupled with confocal laser scanning microscopy (CLSM), observed moreover following caryopsis inoculation plant can colonize rhizoplane, surface as well endorhiza, crossing rhizodermis up vascular...
The diversity of a population 52 halophilic actinomycetes was evaluated by polyphasic approach, which showed the presence members Actinopolyspora, Nocardiopsis, Saccharomonospora, Streptomonospora, and Saccharopolyspora genera. One strain considered to be new member last genus, several other strains seemed species. Furthermore, 50% were active against broad range indicators contained genes encoding polyketide synthetases nonribosomal peptide synthetases.
Rhizoctonia solani is one of the most problematic soil-borne pathogenic fungi for several crop cultures worldwide. This study highlights effectiveness high-antagonistic Streptomyces rochei strain PTL2, isolated from root tissues Panicum turgidum, in controlling R. damping-off and growth promotion tomato (cv. Marmande) seedlings. The isolate PTL2 was characterised vitro biocontrol plant growth-promoting traits. It exhibited remarkable positive results all trials, including production hydrogen...
The genus Actinomadura comprises Gram-positive bacteria found in diverse natural environments and is classified the family Thermomonosporaceae within order Streptosporangiales . Some species exhibit considerable phylogenetic taxonomic overlaps, prompting a comprehensive investigation that integrates phylogenetic, phylogenomic comparative genomic analyses to elucidate status of two species. livida JCM 3387ᵀ catellatispora DSM 44772 T shared 16S rRNA gene sequence similarity 99.9% digital...
The genus Saccharopolyspora consists of Gram-positive bacteria that are found in nature. genus, belonging to the family Pseudonocardiaceae and order Pseudonocardiales , has shown considerable phylogenetic taxonomic overlaps. Therefore, a phylogenetic, phylogenomic comparative genomic investigation was conducted elucidate position four taxa. Analysis 16S rRNA genes showed sequence similarity between tested species ranged from 95.59 100%, with hirsuta VKM Ac-666 T as type species. Moreover,...
Avian colibacillosis caused by avian pathogenic Escherichia coli (APEC) strains is a bacterial disease responsible for enormous economic losses in the poultry industry, due to high mortality rates farms, antibiotic therapy costs, and seizures at slaughterhouses. The aim of this study was characterize serogroups molecular features extended spectrum β-lactamase (ESBL)-producing APEC isolates recovered from 248 liver samples 215 broilers 33 turkeys with lesions northeast Algeria. For this,...
The taxonomic position of a soil isolate, strain SA 233 T , recovered from Saharan Algeria was established using polyphasic approach. This isolate has been previously reported to produce three novel dithiolopyrrolone antibiotics, and preliminary chemotaxonomic morphological characteristics suggested that it representative member the genus Saccharothrix . Phylogenetic analysis 16S rDNA sequences, along with detailed morphological, physiological characteristics, indicates belongs represents...
An actinomycete strain named IA1, which produced an antimicrobial compound, was isolated from a Saharan soil in In Amenas, Algeria. The study of the 16S rDNA sequence this permitted to relate it Streptomyces mutabilis NBRC 12800 T (99.93% similarity). Strain IA1 exhibited strong activity against wide range plant pathogenic fungi. One bioactive compound large amounts (46.7 mg L −1 day ), YA, and purified by TLC reverse phase HPLC. structure elucidation pure substance, using combined data UV...
