Do plant biostimulants affect the survival of Escherichia coli in lettuce?

Considering that plant biostimulants can be sprayed multiple times on leafy crops even just before harvest, it is relevant to know the impact of biostimulant applications on Escherichia coli population dynamics of lettuce leaves to ensure food safety. Two trials were carried out to investigate whether the applications of a seaweed extract and a vegetal-derived protein hydrolysate (PH) could affect the E. coli growth in shake flasks (Exp. 1) and plant growth and survival of artificially inoculated E. coli on the leaf surface of lettuce grown in a floating system (Exp. 2).
