Co‐cultivation and Medium Optimization: A Strategy for Discovering Fungal‐derived Protease Inhibitors

Chemistry &Biodiversity, Volume 22, Issue 12, December 2025.
ABSTRACT The fungi Fusarium guttiforme and Phytophthora palmivora were cultivated in four different media (Potato Dextrose Agar, Czapek, rice, and ISP2) and co‐cultured to stimulate fungal interactions and enhance secondary metabolite production. Promising extracts were fractionated, yielding compounds such as the iron complex of fusaric acid (1 ...

Filamentous Fungi transported by birds during migration across the mediterranean Sea. [PDF]

, 2012
The potential for the transport and diffusion of some pathogenic microorganisms by migratory birds is of concern. Migratory birds may be involved in the dispersal of microorganisms and may play a role of mechanical and biological vectors.

4‐Methylbenzhydryl Bromine Resin: Bridging the Gap between 2‐Chlorotrityl Chloride and Wang‐Type Resins for the Solid‐Phase Synthesis of C‐Terminal Acid Peptides

Chemistry–Methods, Volume 5, Issue 12, November 2025.
Methylbenzhydryl bromine resin give good performance in specific condition copared to wang and 2‐chlorotrityl chloride resin. Over the last year, peptides have been consolidated as an important class of biomolecules, receiving increased attention from the pharmaceutical, cosmetic, and food industries. Most peptides currently used in both industrial and

molecular recognition at interfaces [PDF]

, 2014
In order to investigate molecular recognition on surfaces, an azide- functionalized monolayer was deposited on gold. The monolayer was characterized by X-ray photoelectron spectroscopy (XPS) and angle-resolved near-edge X-ray absorption fine structure ...

Unravelling the mechanism of non-ribosomal peptide synthesis by cyclodipeptide synthases. [PDF]

, 2014
International audienceCyclodipeptide synthases form cyclodipeptides from two aminoacyl transfer RNAs. They use a ping-pong mechanism that begins with transfer of the aminoacyl moiety of the first aminoacyl tRNA onto a conserved serine, yielding an ...
