Abstract: Vermicompost content many bacteria that was produce many organic material important. The bacteria could function as probiotics. One of these bacteria was Lactobacillus. Lactobacillus sp. bacteria are expected to have probiotic characteristics for shrimp. This study aims to select and characterize Lactobacillus sp. bacteria from vermicompost. The selection and characterization of microorganisms is the main step in the selection of potential probiotics. Fifty-two bacterial isolates were taken from the collected vermicompost. The bacteria were selected and characterized based on the characteristics of pH, temperature, concentration of NaCl, hemolysis and antibacterial products. The results of the study obtained from the selection were isolates LB37 and LB51 as probiotic candidates. The isolates grew lived on media with pH 4, 6, 8, and temperature of 28℃, 37℃ and 45℃. Both isolates also grew in media at NaCl levels of 0.05; 3.5 and 7.5%. They are not pathogenic bacteria. Isolates LB37 and LB51 produce natural antibacterials that inhibit the growth of Bacillus sp and Escherichia coli.
