Reevaluating a non-conventional procedure to microencapsulate beneficial lactobacilli: assessments on yield and bacterial viability under simulated technological and physiological conditions.

Background: Maintaining viability of beneficial microorganisms applied to foods still constitutes an industrial challenge. Many microencapsulation methodologies have been studied to protect probiotic microorganisms and ensure their resistance from manufacturing through to consumption. However, in many Latin-American countries such as Argentina there are still no marketed food products containing microencapsulated beneficial bacteria.

Lactic acid bacteria with promising AFB binding properties as an alternative strategy to mitigate contamination on brewers' grains.

Adsorption of molecules to the cell walls of microorganisms plays an important role in helping to prevent animal exposure to the toxic and carcinogenic effects of aflatoxins (AFs). The aim of this study was to evaluate the ability of LAB strains, isolated from brewers' grains, to adsorb aflatoxin B (AFB). All LAB were able to reduce the bioavailability of AFB from phosphate buffered-saline (PBS).

Biological control of AFB1-producing Aspergillus section Flavi strains isolated from brewer's grains, alternative feed intended for swine production in Argentina.

The aim of the present study was to investigate the inhibitory activity of lactic acid bacteria (LAB) isolated from brewer's grains on Aspergillus section Flavi growth and aflatoxin B1 production. The Aspergillus strains tested were inhibited by all the LAB strains assayed. The isolates Lactobacillus brevis B20, P.

Antimicrobial activity, inhibition of urogenital pathogens, and synergistic interactions between lactobacillus strains.

Lactobacillus fermentum strain L23 and L. rhamnosus strain L60 were selected as an alternative treatment to prevent or treat urogenital infections based on their probiotic properties and production of bacteriocins. The objectives of the present work were to study the inhibitory activities of these two bacteriocin-producing strains, and to analyze the interactions between pairs of bacteriocins that inhibit urogenital pathogens.
