چکیده
Background and Objectives: Probiotic bacteria are able to absorb fatty acids present in the culture medium and convert them into intracellular fatty acids, which may affect the physicochemical properties of probiotics. Subsequently, changing the composition of cellular fatty acids of probiotics improves the electron acceptance capacity of these microorganisms, and results in an increased adhesion to the intestinal mucus. In the present study, the effect of fatty acids on the physicochemical and adhesion properties of Lactobacillus species was investigated.
Materials and Methods: Seven fatty acids including palmitic, stearic, α-linolenic, γ-linolenic, oleic, linoleic and arachidonic acids were used for the enrichment of MRS medium. Afterwards, fatty acid content and adhesion property were measured using GC and spectrophotometer, respectively.
Results and Conclusion: The results showed that the type of microorganism and fatty acid had a significant effect (p≤0.05) on the adhesion property of probiotics. According to the results, the highest membrane fatty acid content was found for myristic and elaidic acid, and the lowest content for α-linoleic acid.
