Abstract

However, the Lactobacillus probiotics strains have received increasing attention as future antimicrobial agents to prevent foodborne pathogen through practical applications. Objective:This study aims to evaluate anti-adhesive potential of selected Lactobacillus isolates against Salmonella spp. under conditions that mimic food processing in Iraq. Salmonella biofilms pose a considerable challenge due to their increased resistance to conventional disinfectants and potential for subsequent re-contamination of food contact surfaces. Which is to isolate and characterize a range of Lactobacillus strains based on different antimicrobial activity, adhesion, and antagonistic unit. Novel anti-biofilm efficacy was tested by standard microtiter plate assays and industrially relevant surface adhesion models. Inhibition of biofilm formation, disruption of already formed biofilms at diverse development stages with specific Lactobacillus sharing similarity to the source strain and also showing broad antimicrobial profiles towards respective Salmonella serovars were observed in all possible conditions. The inhibitory processes that were positively associated are competitive exclusion, pH reduction and the production of metabolites which negatively affect QS pathways and biofilm structural integrity. Furthermore, treated surfaces yielded significantly lower counts of viable Salmonella cells compared to untreated controls. Abstract The findings in this study suggest that probiotic Lactobacillus strains can be potential candidates for environmentally friendly biocontrol strategies of biofilm in food industry [37 60]. Such biological based intervention might help in decreasing dependency upon chemical sanitizers and elevating the food safety standards, particularly those geographic zones where industrial hygiene administration is a difficulty. Later studies should focus on optimization of formulation, and examination of applicability over larger scales.
