The present invention is related to at least one isolated
bacterial strain selected from at least one of the species selected from the group comprising or, alternatively, consisting of: i)
Lactobacillus plantarum, ii)
Lactobacillus acidophilus, and iii)
Lactobacillus crispatus, or mixtures of said at least one isolated
bacterial strain thereof, for use in a method of metals gut microbial
bioremediation. Preferably, said metals involved in the gut microbial
bioremediation are
heavy metals, which are selected from the group comprising or, alternatively, consisting of Ag, Be, Ba, Cd, Cr, Mn, Hg, Pb, Cu, V, and As preferably from Cd, Cr, Hg, and Pb; or Al, or mixtures thereof. In particular, said at least one isolated
bacterial strain belonging to the specie i)
Lactobacillus plantarum is selected from the group comprising or, alternatively, consisting of Lactiplantibacillus plantarum 476LL 20 bi LP01 (LMG P- 21021), Lactiplantibacillus plantarum 776 / 1 bi LP02 (LMG P-21020), and Lactiplantibacillus plantarum LP14 (DSM 33401) or mixtures thereof, said at least one isolated bacterial strain belonging to the specie ii)
Lactobacillus acidophilus is selected from the group comprising or, alternatively, consisting of
Lactobacillus acidophilus LA02 (DSM 21717), and
Lactobacillus acidophilus LA06 (DSM 23033), and said at least one isolated bacterial strain belonging to the specie iii)
Lactobacillus crispatus is identified as
Lactobacillus crispatus LCR04 (DSM 33487). Furthermore, the present invention regards a mixture comprising at least one isolated bacterial strain as above indicated, as well as a composition comprising said mixture, for use in a method of metals gut microbial
bioremediation, wherein said metals involved in the gut microbial bioremediation are
heavy metals, which are selected from the group comprising or, alternatively, consisting of Ag, Be, Ba, Cd, Cr, Mn, Hg, Pb, Cu, V, and As preferably from Cd, Cr, Hg, and Pb; or Al, or mixtures thereof and in the prevention and or reduction of the harmful effects of
heavy metals on gut health.
