3.3.3. Invasive growth plate-washing assay
Fig. 2shows the invasiveness of five representative strains observed after growth on agar media with various supplements and washing the colony under a stream of water. Under simulated fermentation condi-tions, the strains exhibited different invasive behavior, from no inva-siveness (e.g. Sc384) to various invasiveness degree modulated also by either the presence of catechin or natural mix of polyphenols (e.g.Sc1321, Sc2621)
