The article presents research on Xylan-mediated aggregation of Lactobacillus brevis (L. brevis), its relationship with the surface properties and mucin-mediated aggregation of the bacteria. It mentions the aggregation of L. brevis strains upon the addition of xylan after screening for lactic acid bacteria that interact with plant materials. TheIt adds that xylan-mediated aggregation of L. brevis is considered to be caused by electrostatic interaction between the cells and xylan.
