During cheese ripening, the bacterial strain Pediococcus acidilactici FAM18098 produces the non-proteinogenic amino acid, α-aminobutyrate (AABA). The metabolic processes that lead to the biosynthesis of this compound are unknown. In this study, 10 P. acidilactici, including FAM18098 and nine Pediococcus pentosaceus strains, were screened for their ability to produce AABA. All P. acidilactici...

Oomycetes are pathogens responsible for many plant diseases over the world and the economical impact of their damage is quite important. Although these organisms show a mycelar growth, their biology is quite different from that of fungi. This makes them not easy to fight against and up to now no fungicide is able to stop an epidemy due to Oomycetes in a durable way. The particular biology of...
