Summary: The bacterial isolate Streptomyces sp. FXP04 obtained from the rhizosphere soil of potato plants showed significant inhibition against the mycelial growth of Phytophthora infestans, the pathogen causing potato late blight. The genome sequencing of Streptomyces sp. FXP04 identified 15 gene clusters responsible for the biosynthesis of secondary metabolites, including the antimicrobial compound Piericidin A. Metabolomic analysis confirmed the presence of Piericidin A, which was shown to inhibit the growth of P. infestans. These findings suggest that Streptomyces sp. FXP04 could be a potential biocontrol agent for potato late blight, with Piericidin A as the key antimicrobial secondary metabolite.

Summary: Endophytic fungi, such as black aspergilli, have the potential to produce bioactive secondary metabolites. This study isolated 25 endophytic fungal strains associated with Malus domestica and identified one strain, Aspergillus tubingensis strain AN103, that showed the highest activity. Chemical investigations of its fermented cultures yielded four compounds, which exhibited moderate-to-potent antibacterial, antifungal, and cytotoxic activities. These compounds have the potential to be developed into drugs for various medical and pharmaceutical applications.

Summary: Finding new antibacterial agents from natural products is crucial due to the increase in antibiotic-resistant pathogens. This study focuses on characterizing and exploring actinomycetes from Nepal, which have not been extensively studied for their potential in developing countries. The research combines in silico molecular docking and antimicrobial assays to examine the efficacy of actinomycete-derived chemical scaffolds. The study identifies three Streptomyces species with significant antimicrobial activities and explores their molecular interactions with target proteins. These findings highlight the potential for discovering novel and therapeutically relevant antimicrobial agents from Streptomyces species in Nepal.

Summary: Fungal microbes, particularly Fusarium spp., have been identified as a prolific source of secondary metabolites (SMs) with diverse chemical structures and broad-spectrum antimicrobial properties. A thorough literature search and data analysis revealed the discovery of 185 antimicrobial natural products derived from Fusarium strains by the end of 2022. These substances exhibit various antimicrobial effects, including antibacterial, antifungal, antiviral, and antiparasitic activities. Furthermore, suggestions for future research on efficient discovery of novel bioactive SMs from Fusarium strains are proposed.

Summary: Multi-drug resistant bacteria pose a serious global problem, necessitating the search for new antimicrobial agents. Silver nanoparticles (Ag-NPs) have been proposed as a new generation of antimicrobial agents, showing antimicrobial activity against multi-drug resistant Gram-positive and Gram-negative pathogens. Egyptian Streptomyces roseolus was used for the first time to biomediate the synthesis of Ag-NPs, and characterization confirmed the presence of bioactive functional groups acting as bioreducing/stabilizing agents for Ag-NPs.

Summary: In this study, endophytic actinobacterial strain 3R004T was isolated from the root of Justicia subcoriacea collected in Thailand. Through a polyphasic approach, it was identified as a member of the genus Streptomyces, producing actinomycin D as a major secondary metabolite. The taxonomic position and characteristics of strain 3R004(T) were determined using morphological, chemical, and phylogenomic analyses.
