Misuse of antibiotics led to the world wide spread of antimicrobial resistance threatening human lives. The notable resistance of bacterial cells to antibiotics and immune system is the difficulty associated with biofilm-linked illnesses. Natural products from plant origin with antibiofilm activity could provide more therapeutic activity with fewer adverse effects.

Article Synopsis
  • Scientists studied fungi from plants to find out if they can help create useful substances.
  • They tested three types of fungi from different parts of the plants and mixed them with various chemicals to see how they would grow.
  • The results showed that certain chemicals made the fungi produce compounds that could potentially fight breast cancer cells.

In the current study, the actinomycetes associated with the red sea-derived soft coral Sarcophyton glaucum were investigated in terms of biological and chemical diversity. Four different media, M1, ISP2, Marine Agar (MA), and Actinomycete isolation agar (AIA) were used for the isolation of three strains of actinomycetes that were identified as Streptomyces sp. UR 25, Micromonospora sp.

Article Synopsis
  • Plant secondary metabolites are important for developing new and safe drugs, and this study focuses on using ethanolic extract from Roxb. Sweet to create eco-friendly zinc oxide nanoparticles (ZnO NPs) with a small average size of 6.80 nm.
  • Various phenolic compounds were identified in the extract, with chlorogenic acid being the most abundant at 1803.84 μg/g.
  • The study found that ZnO NPs have a stronger antiviral effect against coronavirus 229E than the extract alone, and their combination shows the best results, indicating potential for future biomedical applications.

Aim: This study aimed to use one strain many compounds approach (OSMAC) to investigate the cytotoxic potential of Aspergillus terreus associated with soybean versus several cancer cell lines, by means of in-silico and in vitro approaches.

Methods And Results: Fermentation of the isolated strain was done on five media. The derived extracts were investigated for their inhibitory activities against three human cancer cell lines; mammary gland breast cancer (MCF-7), colorectal adenocarcinoma (Caco-2), and hepatocellular carcinoma (HepG2) using MTT Assay.

This review summarizes the recent advances in the elicitation approaches used to activate the actinomycete genome's cryptic secondary metabolite gene clusters and shows the diversity of natural products obtained by various elicitation methods up to June 2022, such as co-cultivation of actinomycetes with actinomycetes, other non-actinomycete bacteria, fungi, cell-derived components, and/or algae. Chemical elicitation and molecular elicitation as transcription factor decoys, engineering regulatory genes, the promoter replacement strategy, global regulatory genes, and reporter-guided mutant selection were also reported. For researchers interested in this field, this review serves as a valuable resource for the latest studies and references.
