A study on the application of synthetic antimicrobial peptides derived from plants for the reduction of yeast spoilage in food
Food spoilage caused by the undesirable growth of microorganisms contributes to the crisis of food waste and food loss worldwide. Bacterial and fungal microorganisms can grow and spread in food, resulting in the spoilage of many food products intended for human consumption. Food preservatives and …

Mechanistic Studies of Lantibiotic Biosynthetic Enzymes and Discovery of Novel Lanthionine-Containing Peptides
… the prototypic lantibiotic widely used as a food preservative. The X-ray crystal structure of NisC revealed the presence of a zinc ion and provided insights into the molecular mechanism of the cyclization reaction. Mutagenesis of residues conserved among the LanC family of proteins and …

Synthesis of Biologically Relevant Sphingolipid Analogues
… 20 steps starting from D-ascorbic acid, a common food preservative. Key reaction in this synthetic approach was a fully regioselective epoxide opening with lithium 1,3-dithiane. In addition, a fully stereoselective Grignard reaction gave access to D-ribo-N-homophytoceramide.

Investigating the Effects of Sodium Benzoate on Fat Deposition, Pharyngeal Pumping, and Related Genetic Mechanisms in Caenorhabditis elegans
Sodium benzoate is a widely used food preservative common in many household products due to its antibacterial and antifungal activities. However, many of its side effects other than as a preservative has been under research as of late to try and assess the validity of it being a generally regarded …

Fundamental study of natural and synthetic antimicrobial peptides as novel preservatives against fungal food spoilage
A large part of food loss is associated with the development of fungal contamination at early or late stages of production. This spoilage, via the production of mycotoxins, has potentially disastrous consequences on consumers’ health. The overuse of chemical antimicrobials in foods (e.g., sorbates) …
