Aloe vera is plant which has strong antibacterial, anticancer, antifungal and wound healing. Probiotic bacteria are live microorganisms that confer a health benefit on the host when administered in adequate amounts. Synbiotic is relationship between aloe vera and probiotic bacteria that are found together in the gastrointestinal tract system. Aim of the this study is to investigate effects of aloe vera on probiotic bacteria Lacticaseibacillus rhamnosus GG (LGG) and Lactobacillus acidophilus LA-5 (LA-5). For this purpose, LGG and LA-5 were grown in different concentrations of aloe vera extract and effects of aloe vera extract on bacterial growth kinetics, bacterial auto-aggregation and resistance of pepsin were investigated. Results showed that aloe vera extracts did not showed inhibitory effect on the microbial growth of LGG and LA-5. Aloe vera increased the auto-aggregation of LA-5 while it decreased the auto-aggregation of LGG. Furthermore, aloe vera increased the pepsin resistance of LGG but it effetc the pepsin resistance of LA negatively. These results indicated that phytic acid may enhance the probiotic property of the LGG and LA-5.
