Three human probiotics, Lactobacillus rhamnosus strains GG and LC-705, and Bifidobacterium lactis strain Bb12, were found to bind the cyanobacterial peptide toxin microcystin-LR from water solutions. The highest removal percentage was 46%, observed with heat-treated L. rhamnosus strain GG (10(10) cells/ml) and a microcystin-LR concentration of 0.5 microg/ml during an incubation of 7 h at 35 degrees C.
研究发现，三种人类益生菌，即鼠李糖乳杆菌GG株和LC-705株以及双歧杆菌Bb12株，能够结合水溶液中的蓝藻肽毒素微囊藻毒素-LR。最高去除率为46%，这是在35℃下将经热处理的鼠李糖乳杆菌GG株（10¹⁰个细胞/毫升）与浓度为0.5微克/毫升的微囊藻毒素-LR孵育7小时时观察到的。
