An experiment using a standard strain of Lactobacillus amylovorus TISTR1110 to test for the capability of carbohydrate utilisation of nine cultivars of rice found that L. amylovorus TISTR1110 could utilise carbohydrate from all cultivars and also exhibit nonhaemolytic properties. After testing the viability of the strain under simulated gastrointestinal tract conditions by enumeration after 5 h, the results showed that the amount of L. amylovorus TISTR1110 present was 4.0 × 105 CFU/mL or a 73.78% survival rate. From the evaluation of Thai rice cultivars as carriers in probiotic products, the highest amount of probiotic bacteria was found in baked and encapsulated glutinous Luem Pua Thai sticky rice up to 4.9 × 106 CFU/g or a survival rate of 69.39 ± 0.06%. The second highest rate (4.8 × 105 CFU/g) was found in heat–moisture steamed rice of Riceberry rice cultivar or a survival rate of 59.74 ± 0.11%. After testing the capability of adherence using SEM, the results showed that glutinous Luem Pua sticky rice resulted in considerably high survival rate of probiotic bacteria compared with other rice. Additionally, the microbiological safety test reported that the amounts of contaminants were acceptable. 相似文献
