A preliminary study of the strain's tolerance to several heavy metal ions was made. QH-1 was a Gram-negative, short rod, facultative aerobe. The strain could oxidize reduced sulfur compounds to obtain energy. The strain had a high acid production capacity, was resistant to acid, and showed a long logarithmic growth phase of probably 15 days. The strain grew well in a pH environment between 6.0 and 0.6 and could survive in a low pH environment. Using the 16S rRNA sequence and homology analysis, a phylogenetic tree of the strain with related species was constructed. The results showed that QH-1 is a strain of Acidithiobacillus thiooxidans. QH-1 has a high tolerance to Zn2+ and Cu2+ and a poor tolerance to Mo2+. %K Acidithiobacillus thiooxidans %K isolation and purification %K 16S rRNA %K growth characteristics %K metal tolerance
