Objective: To evaluate the global scientific research and the tendencies on acidophilic organism during the past 30 years. Studies in the acidophilic microorganism had significantly increased.
Methods: Articles related with the acidophilic organism were assessed by distribution of countries, institutes, journals using the method of bibliometric analysis.
Results: The results showed seven industrialized countries and four major developing countries were all listed in the top 20 most productive countries, which suggested economic conditions had an important effect on academic development. In addition, researchers in different institutions were more tending to cooperate. However, cooperation always occurred in the interior of the country. Through a synthetic analysis of the paper titles, author keywords and
Keywords Plus, it revealed that “resistance to metal” attracted more attentions. Besides, this characteristic was also widely applied in bioleaching. At the level of research environment, “water” was the dominant position, such as acid mine drainage.
Conclusions: Study in the acidophilic microorganism had significantly increased. Cooperation had become the trend. Moreover, economic conditions had an important effect on academic development.
