Abstract

Soybean tempeh can reduce the severity of diarrhoea through the inhibition of enterotoxigenic Escherichia coli (ETEC) adhesion to intestinal cells. This bioactivity is due to the presence of bioactive oligosaccharides derived from degradation of soybean matrix by fungi. Tempeh also contains other microorganisms such as bacteria and there has been no report whether bacteria can also influence the anti-adhesion bioactivity of tempeh extract against ETEC. In this research, we quantified bacterial population in tempeh samples using real time polymerase chain reaction (RT-PCR) method and measured the anti-adhesion bioactivity against ETEC of the extract using yeast agglutination assay. Data from both analyses were compared to see if there is any correlation between the two variables. Bacterial quantification with RT-PCR was focused on the enumeration of total bacteria and two specific major bacterial phyla in tempeh: Firmicutes and γ-Proteobacteria. There was a significantly strong positive correlation (R = 0.733) between total number of bacteria with anti-adhesion bioactivity of tempeh. However, there was no strong correlation between the number of Firmicutes and y-Proteobacteria with anti-adhesion bioactivity. Our finding indicates that the anti-adhesion bioactivity of tempeh tends to increase following the abundance of bacteria but is not significantly affected by specific major bacterial phylum.
