Peptaibols are a family of antimicrobial peptides, which are synthesized by non-ribosomal peptide synthetases (NRPS) and contain high proportions of alpha-aminoisobytyric acid (Aib). Up to now, 317 peptaibols have been identified, and the majority of them are produced by Trichoderma strains. In this review, we described the diversity, fermation, purification, identification and biosynthesis of peptaibols from Trichoderma.

Antimicrobial peptides (AMPs) are promising agents for treating antibiotic-resistant bacterial infections. Although discovering novel AMPs is crucial for combating multidrug-resistant bacteria and biofilm-related infections, their clinical potential relies on precise, real-time evaluation of efficacy, toxicity, and mechanisms. Optical diffraction tomography (ODT), a label-free imaging technology, enables real-time visualization of bacterial morphological changes, membrane damage, and biofilm formation over time.

Antimicrobial peptides (AMPs) are small peptides that play an important role in disease defense. As the problem of pathogen resistance caused by the misuse of antibiotics intensifies, the identification of AMPs as alternatives to antibiotics has become a hot topic. Accurately identifying AMPs using computational methods has been a key issue in the field of bioinformatics in recent years.

A series of tripodal (three-arm) lysine-based peptides were designed and synthesized and their self-assembly properties in aqueous solution and antimicrobial activity were investigated. We compare the behaviors of homochiral tripodal peptides (KKY)K and a homologue containing the bulky aromatic fluorenylmethoxycarbonyl (Fmoc) group Fmoc-(KKY)K, and heterochiral analogues containing k (d-Lys), (kkY)K and Fmoc-(kkY)K. The molecular conformation and self-assembly in aqueous solutions were probed using various spectroscopic techniques, along with small-angle X-ray scattering (SAXS) and cryogenic-transmission electron microscopy (cryo-TEM).

Acylation is a common method used to modify antimicrobial peptides to enhance their effectiveness. It increases the interactions between the peptide and the bacterial cell membranes. However, acylation can also reduce the selectivity of the peptides by making them more active on eukaryotic membranes, which can lead to unintended toxicity.
