Tempoyak is a traditional Bengkulu fermented food prepared from spontaneous fermentation of durian (Durio zibethi- nus) by wild microorganisms. Tempoyak is found not only in Bengkulu but also as long as Sumatera island with differ- ent names, and also in Malaysia. Tempoyak is a Melayu term meaning fermented durian. The research was conducted to identify microflora in tempoyak, and to select the species of microorganisms which were able to ferment durian ef- fectivelly. The data in this study were laboratory analysis. Samples were collected weekly in a month from productions centre of tempoyak and traditional markets, and analyzed microbiologically to determine and identify the bacteria, yeasts and molds in tempoyak. There were four specieses of lactic acid bacteria found in fermented durian namely Pediococcus acidilactici, Lactobacillus plantarum Lactobacillus curvatus and Leuconostoc mesentroides. While two specieses which were not lactic acid bacteria namely Staphylococcus saprophyticus and Micrococcus varians. One species of yeast was Kluyveromyces marxianus. The molds were identified as Rhizopus oryzae, Monilia sitophila, Mucor roxii, Aspergillus repens and Penicillium sp. Among these specieses three specieses were produced lactic acid namelly Rhizopus oryzae, Monilia sitophila,and Mucor roxii. While Aspergillus ripens and Penicillium sp did not pro- duce lactic acid so these specieses might not function in fermentation process.
