Diversity of Oligopeptide Transport in Yeast and Its Impact on Adaptation to Winemaking Conditions

Frontiers in Genetics, 2020
Nitrogen is an essential nutrient for yeasts and its relative abundance is an important modulator of fermentation kinetics. The main sources of nitrogen in food are ammonium and free amino acids, however, secondary sources such as oligopeptides are also ...

Chemotaxis to oligopeptides by Pseudomonas aeruginosa [PDF]

Applied and Environmental Microbiology, 1994
A number of peptides were evaluated as chemoattractants for Pseudomonas aeruginosa. Several strains recognized tri-, tetra-, penta-, and hexapeptides in a capillary tube assay. Tripeptides altered at the carboxyl terminus were good attractants, whereas tripeptides altered at the amino terminus did not serve as chemoattractants.
