ISOLASI, POTENSI DAN KARAKTERISASI BAKTERI ALAMI SUSU KERBAU SEGAR DARI DAERAH AIA DINGIN KECAMATAN LEMBAH-GUMANTI SEBAGAI KANDIDAT PROBIOTIK

Natural bacteria from three buffalo milk products from Lembah Gumanti District, Solok Regency, West Sumatra have been analyzed and compared. This study aims to analyze the composition of microflora and proteolytic bacteria in buffalo milk, to compare the character of potential acid fermentation isolates as probiotic candidates. The study was conducted with survey methods and data were analyzed descriptively. The results of this study include, the proportional presence of fermentative bacteria in fresh buffalo milk from the highest three different samples obtained in Sample B (95.5x〖10〗^6cfu/ml), followed by Sample C (88.5x〖10〗^6cfu/ml) and Sample A (83.5x〖10〗^6cfu/ml), potential isolates of fresh buffalo milk including Lactobacillus (Lactobacillus sp. 1 (SSKA1, SSKB1, SSKC1), Lactobacillus sp2. (SSKA2, SSKB2) and Lactobacillus sp3. (SSKC2) and the highest Fermentative Index found in SSKC2 isolates, highest Proteolytic Index found in SSKA1 isolates, highest Amilolytic and Lipolytic Index found in SSKB2 isolates. Hemolysis Tests of the six isolates (SSKA1, SSKA2, SSKB1, SSKB2, SSKC1, and SSKC2) were not pathogenic (negative pathogens) which were marked d with no formation of clear zone regions (zone of hemolysis) around isolates, and SSKA1, SSKA2, SSKB1, SSKB2, SSKC1, and SSKC2 including the class of lactic acid bacteria
