“…This is in line with the research of Zuraidah et al, (2020), that the isolates of thermophilic bacteria found are round, irregular, and filamentous, have a white and yellowish color and the colony surface is smooth and not slimy. Based on Kasi et al, (2020), the characteristics of bacterial isolates obtained are round and iregullary with convex and flat elevations and white in color.…”

The hot spring of Pentadio Resort is one of the geothermal areas likely to be the place of bacteria or microorganisms that can produce amylolytic enzymes. This research aims to analyze bacteria in the Pentadio Resort hot springs that possess the potential to produce amylase enzymes, analyze the characteristics of bacterial isolates that produce amylase enzymes in Pentadio Resort hot springs and determine the types of bacteria that produce amylase enzymes in Pentadio Resort hot springs. The research employs a qualitative and descriptive method. The research involved several methods, including sample collection, media preparation, isolation and selection of thermophilic bacterial isolates, purification of thermophilic bacterial isolates, selection of isolates producing amylase enzymes, identification of selected isolates (motility test, biochemical test, gram staining), and molecular identification. The research yielded seven isolates, and isolate code A6 demonstrated the potential to produce amylase enzymes with a clear zone size of 23,26 mm, bacillus, gram positive, and positive motility. Subsequently, molecular identifidation was carried out in which, based on the results of phylogenetic tree reconstractiopisalate A6 was related to the bacteria Bacillus cereus strain MD 152, which belongs to the Bacillus cereus bacteria

“…Spores are formed when subjected to stress which serves to protect bacteria from unfavorable external factors by surviving extreme environments such as heating, drought due to high temperatures, radiation, lack of nutrients, acid conditions, freezing and chemicals. Bacteria form spores when environmental conditions are no longer optimal for growth and development, for example the medium dries up, the nutrient content shrinks and so on [15].…”

Research about the isolation, screening and partial characterization of thermophilic bacteria that produce protease from Bukik Gadang hot springs, Solok Regency, was carried out at the Basic Biology Laboratory, UPT Basic and Central Laboratory, Andalas University in January - April 2022. This study aims to obtain isolates of thermophilic bacteria that indicated protease production and to determine the partial characterization of thermophilic bacteria that indicated protease production from Bukik Gadang hot springs, Solok Regency. This study used a survey method and purposive sampling technique. The results of this study obtained 18 isolates from 20 isolates of thermophilic bacteria which indicated protease production, with one isolate of TPBG-03 having the potential to produce protease. Partial characterization by 10 isolates of thermophilic bacteria indicated protease production was generally Gram positive, bacillus cell shape, spore-forming, catalase positive and motile.Keywords - Hot Springs, Isolation, Protease, Screening, Thermophilic Bacteria
