Biocontrol Potential of Some Rhizospheric Soil Bacterial Strains against and Subsequent Effect on Growth of Two Tunisian Wheat Cultivars.

PGPR (Plant Growth Promoting Rhizobacteria) are used as biofertilizers and biological control agents against fungi. The objective of this work was to evaluate the antagonistic activities of some bacterial strains isolated from soil against four phytopathogenic fungal strains (, , sp. and ).

Diversity and adaptation properties of actinobacteria associated with Tunisian stone ruins.

Stone surface is a unique biological niche that may host a rich microbial diversity. The exploration of the biodiversity of the stone microbiome represents a major challenge and an opportunity to characterize new strains equipped with valuable biological activity. Here, we explored the diversity and adaptation strategies of total bacterial communities associated with Roman stone ruins in Tunisia by considering the effects of geo-climatic regions and stone geochemistry.

Fungal Community Investigation from Propolis Natural Products: Diversity and Antibacterial Activities Evaluation.

Discovering new species and interesting bioactive metabolites from customary sources is becoming progressively laborious. Propolis constitutes the largest diversified reserve of microbial constituents in the beehive. However, fungal communities associated with these environments remain insufficiently established.

The Impact of the Inoculation of Phosphate-Solubilizing Bacteria on Phosphorus Availability and Bacterial Community Dynamics of a Semi-Arid Soil.

The bacterial genus has been widely evaluated as promising bacteria to increase phosphorus (P) availability in soil. The aim of this study was to characterize the phosphate solubilizing (PS) activity of a strain and to evaluate the impact of its application in a semi-arid soil on phosphate availability and structure of the bacterial communities as a whole. An incubation experiment under close-to-natural soil environmental conditions was conducted for 15 days at 30 °C.

Isolation, Characterization and Chemical Synthesis of Large Spectrum Antimicrobial Cyclic Dipeptide (l-leu-l-pro) from V16R3Y1 Bacteria Extracts. A Novel H NMR Metabolomic Approach.

Streptomyces is the most frequently described genus of Actinomycetes, a producer of biologically active secondary metabolites. Indeed, the Streptomyces species produces about 70% of antibiotics and 60% of antifungal molecules used in agriculture. Our study was carried out with the goal of isolating and identifying antimicrobial secondary metabolites from V16R3Y1 isolated from the date palm rhizosphere (southern Tunisia).
