NOVELTY - Domestic cultivation method of Thiobacillus thioparus involves inoculating Thiobacillus to culture basal medium to obtain initial discharge sulfur Thiobacillus after activation. The initial discharge of sulfur bacteria after activation of Thiobacillus, is inoculated in enriched media. Thiobacillus enrichmeulture broth is inoculated to new rich medium at 28-31 degrees C at 150-200 revolutions/minute and bacteria are cultured to a concentration of 1asterisk108 colony forming unit/mL. The acclimation temperature is increased to 4-6 degrees C and cultured for 1-2 days.    USE - Method for domestication of sulfur Thiobacillus used in high temperature aerobic composting (claimed).    ADVANTAGE - The method enables to domesticate sulfur Thiobacilluswhich can speed up the metabolism of sulfur bacterium leading to nutrient utilization. Discharge of sulfur Thiobacillushas favorable growth and rapid enrichment. The method also solves the discharge of sulfur in the aerobic composting at high temperatures.    DETAILED DESCRIPTION - Domestic cultivation method of Thiobacillus thioparus involves inoculating Thiobacillus to culture basal medium to obtain initial discharge sulfur Thiobacillus bacteria after activation. The initial discharge of sulfur bacteria after activation of Thiobacilli, is inoculated in enriched media. Thiobacillus,enrichment culture broth is inoculated to new rich medium at 28-31 degrees C at 150-200 revolutions/minute and bacteria are cultured to a concentration of 1asterisk108 colony forming unit/mL. The acclimation temperature is increased to 4-6 degrees C and cultured for 1-2 days. It is then inoculated into new enrichment medium, at the same temperature as of acclimation culture broth and cultured to a concentration of 1asterisk108 colony forming unit/mL. Acclimation culture temperature is increased to 4-6 degrees C and process of culturing is repeated. When acclimation culture temperature is raised to 44-46 degrees C and the bacterial concentration is 1asterisk108 colony forming unit/mL, the acclimation temperature taming is completed. High temperature acclimation is performed when temperature of bacterial culture is above 44-46 degrees C and culturing is performed at 47-49 degrees C at 150-200 revolutions/minute and acclimation is for 2 to 3 days, and then inoculated into a new enrichment medium, in the same temperature of acclimation culture broth to a concentration of 1asterisk108 colony forming unit/mL. Acclimation temperature is increased to 2.5-3.5 degrees C and cultured for 1-2 days, and then inoculated into a new enrichment medium, at the same temperature acclimation culture broth to a concentration of 1asterisk108 colony forming unit/mL. When the culture acclimation temperature reaches 59.5-60.5 degrees C, and the bacterial concentration is above 1asterisk107 colony forming unit/mL, high-temperature acclimation is completed. Environmental acclimation of sulfur bacteria Thiobacillus,is performed by inoculating liquid culture into compost at 28-31 degrees C at 120-180 revolution/ minute conditions and bacteria are cultured to a concentration above 1asterisk109 colony forming unit/mL. The liquid culture medium is then inoculated into compost II at 39-41 degrees C at 150-200 revolutions/minute and bacteria are cultured at concentration above 1asterisk108 colony forming unit/mL. The liquid culture medium is inoculated into compost at 49-51 degrees C at 180-220 revolutions/minute and bacteria are cultured at concentration above 1asterisk108 colony forming unit/mL leading to end of domestication. One liter basal medium has 1.0-1.5 g disodium phosphate , 1.5- 2.0 g monopotassium phosphate, 0.1-0.3 g magnesium sulfate heptahydrate, 0.1-0.3 g ammonium sulfate, 0.03-0.05 g calcium chloride, 0.01-0.03 g ferrous chloride, 0.01-0.03 g maganese sulfate, 10.0-15.0 g sodium thiosulfate and the remaining is balanced by water. One liter enrichment medium has 1.0-1.5 g Disodium phosphate, 1.5-2.0 g monopotassium phosphate, 0.1-0.3 g magnesium sulfate heptahydrate, 0.1-0.3 g ammonium sulfate, 0.03-0.05 g calcium chloride, 0.01- 0.03 g ferrous chloride, 0.01-0.03 g maganese sulfate, 10.0-15.0 g sodium thiosulfate, 0.01-0.03 mg pyridoxine hydrochloride, 0.01-0.03 mg riboflavin and the remaining is balanced by water. One liter of liquid medium has 180-220 g initial aerobic composting material which is added to 1 L of water and oscillated for 25-40 minutes followed by filtration and 0.8-1.2% sulfur is added to filtrate. Sterilization is performed for compost liquid medium. One liter of compost liquid medium II has 180- 220 g aerobic composting which is heated to -45 degrees C to 30 degrees C and 1 L of water is added and oscillated for 25-40 minutes followed by filtration and 0.8-1.2% sulfur is added to filtrate and sterilization is performed, for compost liquid medium II. Each liter of compost liquid medium has high temperature 180-220 g aerobic compostable material at 50 degrees C which is added to 1 L of water and oscillated for 25-40 minutes followed by filtration. 0.8-1.2% sulfur is added to filtrate and sterilization is performed, for compost liquid medium to obtain the compost liquid medium III.
