In this paper, the autoaggregating, coaggregating, hydrophobicity, and adhering abilities of 22 Lactobacillus strains belonging to different species were assessed. No correlation existed between autoaggregation and adhesion of the strains belonging to different species, whereas a positive correlation existed between autoaggregation and adhesion of the strains belonging to the same species. After treating with guanidine HCl, the autoaggregating and adhering abilities of some Lactobacillus strains decreased, indicating that surface-bound proteins and other macromolecules played a role in the adhering and autoaggregating abilities. The strains Lactobacillus plantarum 20 and 66 had higher adhesion and coaggregation abilities and should be further studied for their probable probiotic properties. Aggregating, coaggregating, and adhering abilities of Lactobacillus strains could be used as the preliminary criteria for selecting strains having probiotic potential.
本文评估了 22 株属于不同种属的乳酸菌的自聚集、共聚、疏水性和黏附能力。不同种属的菌株的自聚集与黏附之间没有相关性,而同种属的菌株的自聚集与黏附之间存在正相关性。用盐酸胍处理后,一些乳酸菌菌株的自聚集和黏附能力下降,表明表面结合蛋白和其他大分子在黏附和自聚集能力中起作用。植物乳杆菌 20 和 66 株具有较高的黏附和共聚能力,应进一步研究其可能的益生菌特性。乳酸菌菌株的聚集、共聚和黏附能力可作为选择具有益生菌潜力的菌株的初步标准。
