Abstract

Probiotics are live microorganisms that confer health benefits on the host when administered in adequate amounts, such as to support the balance of gut microbiota. In this study, the selected indigenous probiotic strain, Lactobacillus plantarum Mut-7, was used as a starter culture to produce fermented milk. A total of 28 healthy Indonesian youngsters and adults (male/female: 16/12; age 19.4-22.9 years old; normal BMI range 18.6-22.7 kg/m(2)) were supplemented with the fermented milk. This study aimed to determine the recovery of L. plantarum Mut-7 through molecular analysis from the subjects feces after ingestion of 140 mL fermented milk containing 7.0 log(10) CFU/ml of L. plantarum Mut-7 for 15 days. Molecular detection was performed using the rep-PCR technique and sequencing of DNA 16S rRNA. Consumption of fermented milk containing L. plantarum Mut-7 enabled reduction of total E. coli and Coliform non-E. coli in several subjects. It was able to increase the total LAB and total L. plantarum in subjects' feces. The number of L. plantarum and mesophilic LAB increased by 5.5 +/- 1.6 log(10) CFU/g, 1.8 +/- 0.8 log(10). On the other side, thermophilic LAB increased by 2.8 +/- 3.0 log(10) CFU/g in 23 out of 28 subjects. These findings proved that L. plantarum survived in the human gastrointestinal tract. Based on the molecular identification technique using rep-PCR technique and sequencing of gene 16S rRNA, two isolates had similarity to L. plantarum Mut-7 by a coefficient value of 100%.
