Metagenomic analysis of microbial community in over-fermented tempeh. Biodiversitas 20: 1106-1114. Tempeh is a traditional Indonesian food which is made from soybeans through a fermentation process using Rhizopus as a starter culture. Tempeh is now considered as a functional food with many beneficial effects to human health beyond its nutritional value. The microbial community during the further fermentation process of tempeh give typical characteristic taste and flavor. Therefore the over-fermented tempeh is used as a flavoring in some dishes. Metagenomic analysis needed to know the involvement of microbial communities since most of the microbes involved in further fermentation process are unculturable. This research aimed to study the diversity of the microbial community in the over-fermented tempeh (72 hours) using the metagenomic analysis. Seventeen OTUs of fungi in over-fermented tempeh were detected. Among them, 9 OTUs had significant abundance: six species were identified as Tryblidiopsis sichuanensis, Candida sp.2_1., Kluyveromyces marxianus, Trichosporon asahii, Trichosporon gracile, and Trichosporon ovoides, one species was identified in the order level Mucorales, and two fungi species could not be determined.
