Embodiment 1
[0027] Embodiment 1, the isolation of thermophilic acid sulfur bacillus (Acidithiobacillus caldus DX-csu)
[0028] Isolation of Acidithiobacillus caldus DX-csu Collect 10g of ore sample from the ore in Dexing, add it to a triangular flask with 100ml sterile water and glass beads inside, vibrate on a shaker at 170r / min for 20min, take 1ml and add 9ml of sterile water, successively dilute 10 -5 , 10 -6 , 10 -7 , 10 -8 , 10 -9 , 10 -10 Take 1ml of the above suspension and add it into 100ml sterilized 9K medium, repeat each concentration 3 times, place it in a 45°C incubator for 0.5d, 1d and 3d, repeat the above steps 4-5 times for bacteria for separation and purification.
Embodiment 2
[0029] Embodiment 2, identification of thermophilic acid sulfur bacillus (Acidithiobacillus caldus DX-csu)
[0030] (1) The sequencing results of the 16SrRNA gene sequence of the Acidithiobacilluscaldus DX-csu strain showed that the 16SrRNA gene sequence of the Acidithiobacilluscaldus DX-csu strain was shown in the sequence table. It indicated that Acidithiobacillus caldus DX-csu belonged to thermophilic acid sulfur bacillus.
[0031] (2) The results of the whole genome gene sequence sequencing of the Acidithiobacillus caldus DX-csu strain showed that the sequence results of the whole gene of the Acidithiobacillus caldus DX-csu strain were homologously compared with the whole gene sequence of the thermophilic acid sulfur bacillus in Genbank, and the results showed that Acidithiobacillus caldus DX-csu is a new strains.
Embodiment 3
[0032] Embodiment 3, the physiological property of thermophilic acid sulfur bacillus (Acidithiobacillus caldus)
[0033]Four different kinds of thermophilic acid sulfur bacillus (Acidithiobacillus caldus) culture medium solution pH and Eh of four different strains screened in this laboratory have been compared; The pH is obviously lower than the other three, and the results show that the Eh of the present invention is obviously higher than that of the other three, indicating that the strain of the present invention has strong acid production ability. See attached figure 1 ,2.
[0034] Have compared bacterium concentration change with time in the thermophilic acid sulfur bacillus (Acidithiobacillus caldus) substratum of four different kinds; three kinds. See attached image 3 .
