Actinomycetes studies in Tunisia.
Tunisia, located in North Africa, has a diverse topography along the Mediterranean Sea to the Sahara Desert. These environments encompass oases, rhizosphere soils, desert deposits, saline wetlands, offshore oilrigs, and ancient monument rocks. The country's varied environments have led to the isolation of a multitude of actinomycetes. A phylogenetic analysis based on the 16S rRNA sequences of one …

New acid anhydride from Phalaris canariensis with antimicrobial activity assessed through in vitro and in silico approaches.
In this study, a novel fatty acid anhydride, named phalarisin 1, was successfully isolated from the ethyl acetate extract of Phalaris canariensis growing in Tunisia. The structural characterisation of the compound was achieved through various spectroscopic techniques including FT-IR, 1D and 2D-NMR spectroscopy, as well as acidic hydrolysis analyses. Remarkably, phalarisin exhibited potent antimicr…

Purification and structure elucidation of antifungal and antibacterial activities of newly isolated Streptomyces sp. strain US80.
A new actinomycete strain, designated US80 and producing antimicrobial activities against Gram-positive and Gram-negative bacteria and fungi, was isolated from Tunisian oasis soil. Cultural characteristic studies strongly suggested that this strain belongs to the genus Streptomyces. The nucleotide sequence of the 16S rRNA gene (1517 pb) of Streptomyces sp. strain US80 exhibited close similarity (9…

Isolation, purification and partial characterization of antibacterial activities produced by a newly isolated Streptomyces sp. US24 strain.
A new actinomycete strain designated US24 producing antibacterial activities against Gram-positive and Gram-negative bacteria was isolated from Tunisian soil. Culture characteristic studies strongly suggested that the US24 strain belonged to the genus Streptomyces. Analysis of the nucleotide sequence of the 16S rRNA gene of the Streptomyces sp. US24 strain showed high similarity (98%) with the 16S…

Streptomyces tunisialbus sp. nov., a novel Streptomyces species with antimicrobial activity.
A novel actinomycete strain designated S2T was isolated from Tunisian rhizosphere soil of Lavandula officinalis. This isolate exhibited broad spectrum antibacterial activity against several Gram-positive and Gram-negative bacteria and also antifungal activity against yeast and filamentous fungi. The isolate S2T presents morphological and chemotaxonomic characteristics typical of the members of the…

Efficient transformation procedure of a newly isolated Streptomyces sp. TN58 strain producing antibacterial activities.
A new aerobic Gram-positive bacterium designated TN58 producing antibacterial activities against Gram-positive and Gram-negative bacteria was isolated from Tunisian soil. The nucleotide sequence of the 16S rRNA gene (1516 bp) of the TN58 strain showed high similarity (96-98%) to the Streptomyces 16S rRNA genes, especially with that of Streptomyces lavendulae which produces the anti-tumor compound …

Synergistic antifungal activity and potential mechanism of action of a glycolipid-like compound produced by Streptomyces blastmyceticus S108 against Candida clinical isolates.
The present study aimed to investigate a novel antifungal compound produced by Streptomyces blastmyceticus S108 strain. Its effectiveness against clinical isolates of Candida species and its synergistic effect with conventional antifungal drugs were assessed, and its molecular mechanism of action was further studied against Candida albicans. A newly isolated strain from Tunisian soil, S. blastmyce…

Antimicrobial Activities of Some Actinomycetes Isolated from Different Rhizospheric Soils in Tunisia.
Fifty four isolates of actinomycetes were collected from four different rhizospheric soils: 18 strains from palm tree bark and soil, 12 strains from an olive field soil, 9 strains from a coastal forest, and 15 strains from an agriculture soil situated in the Algerian-Tunisian border (Oum Tboul). Based on morphological and cultural characters, the isolates were classified as Streptomyces (42 strain…

Taxonomy, purification and chemical characterization of four bioactive compounds from new Streptomyces sp. TN256 strain.
A new actinomycete strain designated TN256, producing antimicrobial activity against pathogenic bacteria and fungi, was isolated from a Tunisian Saharan soil. Morphological and chemical studies indicated that strain TN256 belonged to the genus Streptomyces. Analysis of the 16S rDNA sequence of strain TN256 showed a similarity level ranging between 99.79 and 97.8% within Streptomyces microflavus DS…
