Antimicrobial activity of Lactobacillus plantarum strains isolated from different environments: a preliminary study
The aim of this study was the investigation of the antimicrobial activity expressed by
Lactobacillus plantarum strains isolated from different fermented matrices (wines, cheese,
fermented sausages, and sourdoughs). A total of 106 strains of L. plantarum (producers) were
tested against 33 undesirable microorganisms (indicators), including both moulds and bacteria.
The antimicrobial activity exerted by growing cells (GC) was evaluated by the spot-on-thelawn,
while the activity of cell free supernatants (CFS), neutralised CFS (nCFS) and CFS treated
with proteases (pCFS) was assessed by the agar well diffusion assay. The antagonistic effect
produced by GC of L. plantarum isolated from wines was higher than that exibited by cells
isolated from other fermented matrices. Moreover, 5 CFS - all from wine strains - as well as the
corresponding nCFS and pCFS were able to inhibit different bacteria and moulds. The results
suggested a relationship between the origin of L. plantarum strains and their antimicrobial
properties, while no relation was found between the intensity of inhibition and the origin of
indicator strains. This fact highlights that the knowledge of conditions characterising different
ecosystems can be helpful in the detection and isolation of L. plantarum strains to be used as
protective agents.
