Article Synopsis
- The genus in question contains bacteria that are significant for humans, animals, and plants, with specific species found in a leukemia patient's blood and in ginseng field soil.
- Comparative analysis of their DNA suggests that these species are nearly identical at 99.3% but display enough differences to consider them distinct subspecies based on genomic metrics.
- The study proposes to classify these strains into new subspecies due to their unique biochemical traits and genetic distinctions.
Article Synopsis
- Citrus black spot disease, caused by the fungus Phyllosticta citricarpa, lowers the market value of citrus fruits and complicates their export due to health regulations.
- Researchers identified a fungal strain, Diaporthe terebinthifolii, which can effectively combat P. citricarpa by screening various culture media for the most productive extracts.
- A specific extract fraction from D. terebinthifolii was found to completely inhibit spore germination of P. citricarpa, suggesting that its metabolites could be developed into an effective alternative for controlling citrus black spot disease.
Article Synopsis
- This study investigated the antimicrobial properties of extracts from 17 endophytic fungi found in the medicinal plant Schinus terebinthifolius, linking them to genera like Alternaria and Penicillium.
- Out of the fungi tested, 64.7% produced antimicrobial compounds, with notable activity against Staphylococcus aureus, Candida albicans, and Pseudomonas aeruginosa under various fermentation conditions.
- The research identified optimal growth conditions for specific fungi, leading to the discovery of active fractions that effectively inhibited methicillin-resistant S. aureus, with two significant compounds identified via gas chromatography-mass spectrometry.
The phytochemical profile and antimicrobial activity of cultivar (cv.) extracts of Lotus uliginosus (cvs. Trojan and Serrano), L.

Design: The minimal concentration of adherence (MICA) was determined to evaluate the antiadherent potential of extracts on the in vitro biofilm formation. The extracts of plants were subjected to thin layer chromatography (TLC) in order to detect what class of compounds was responsible for the antiadherent activity.
