Lactobacillus plantarum was the most common species in the microflora of artisanal Siahmazgi white brined cheese with 41.6% occurrence among the total isolated LAB. In this study, the attachment properties of 5 different L. plantarum strains isolated from Siahmazgi traditional cheese were evaluated by in vitro tests including auto and co-aggregation, hydrophobicity, and cell adhesion. A relatively high amount of auto-aggregation ranged from 58.21 to 73.99% was seen in selected isolates. Co-aggregation was highly variable from 1.46 to 49%, depending on the pathogenic bacteria and L. plantarum isolates. Hydrophobicity was also highly different in tested strains ranging from 6.58 to 73.3%. Two isolates showed great affinity about 73% to chloroform. All the isolates presented high adhesion to Caco-2 cell line up to about 90%. In conclusion, five L. plantarum isolates showed appropriate attachment properties and could be good candidates for further studying, including safety evaluation, that support their use as probiotics.
