Obtaining and Studying the Properties of Composite Materials from ortho-, meta-, para-Carboxyphenylmaleimide and ABS

Researchers developed new plastic materials based on ABS that can resist bacterial and fungal growth, making them ideal for medical equipment and food packaging. By adding special chemical additives (carboxyphenylmaleimides) to the plastic, the materials became antibacterial while maintaining their useful properties like strength and heat resistance. The study tested three different versions of these additives and found that all performed well against dangerous bacteria like E. coli and Staphylococcus aureus, with the potential to reduce infection risks in hospitals and healthcare settings.

Isolation, identification and antibacterial activity of endophytes from the seeds of Panax japonicus

This study investigated microscopic organisms living inside Panax japonicus seeds to understand why these seeds are difficult to grow. Researchers found the best way to clean the seeds and identified ten different microorganism species living in them. Most of these were fungi that may actually prevent seed germination, while certain bacteria species appear beneficial for plant growth and could potentially be used to improve seed cultivation in the future.

Edible Fungi Melanin: Recent Advances in Extraction, Characterization, Biological Activity and Applications

Melanin from edible mushrooms like black wood ear and reishi offers a natural, sustainable alternative to synthetic melanins with impressive health benefits. These mushroom melanins demonstrate powerful antioxidant and antibacterial properties, protect against radiation damage, and can help maintain liver health. New extraction methods using special solvents are making it easier to obtain pure melanin from mushrooms efficiently, opening doors for its use in food, cosmetics, and medicines.

Isolation, identification and antibacterial activity of endophytes from the seeds of Panax japonicus

Researchers isolated and identified 10 different microorganisms (7 fungi and 3 bacteria) living inside Panax japonicus seeds. They found that a specific type of bacteria (Enterobacteriaceae and Pseudomonas) may help promote seed growth, while certain fungi may inhibit it. The study also determined the best way to sterilize seeds before experimentation, which is important for studying plant propagation of this valuable medicinal herb.

Isolation and identification of endophytic fungi from Alhagi sparsifolia Shap. and their antibacterial activity

Researchers discovered ten types of fungi living inside the medicinal plant Alhagi sparsifolia that were never found before. Two of these fungi produced substances that killed harmful bacteria better than standard antibiotics, especially against E. coli. The researchers identified 26 different compounds in these fungi that are responsible for their antibacterial effects. This research opens new possibilities for developing natural antibacterial medicines from fungal sources.

Characterizing antimicrobial activity of environmental Streptomyces spp. and oral bacterial and fungal isolates from Canis familiaris and Felis catus

Researchers collected bacteria and fungi from the mouths of pet dogs and cats, as well as environmental soil bacteria, to search for natural antimicrobial compounds. They found that some of these microorganisms produce substances that can kill harmful bacteria like E. coli and fungi like Candida albicans, especially when combined with existing antifungal medications. Notably, one environmental bacterium (Streptomyces) produced a compound that was even effective against fungal strains resistant to common antifungal drugs, suggesting promising new treatment possibilities.
