Abstract:

Acidithiobacillus spp. are acidophilic chemolithotrophic gram-negative bacteria and capable of oxidizing ferrous iron,sulfur or reduced inorganic sulfur compounds(RISCs)to obtain energy and fix carbon dioxide. Acidithiobacillus spp. are widely distributed in acidic mineral water,hot spring and other acidic environments,and are the main promoter of sulfur and iron cycling in the Earth’s ecosystems. Members of this genus are widely used in the field of bioleaching for the unique metabolic characteristics and extreme environmental adaptability. In this paper,the physiological and metabolic characteristics of Acidithiobacillus spp.and the adaptation mechanism in extreme environments are reviewed,and the application of Acidithiobacillus spp. in industry and agriculture is expounded. The main research directions and key scientific issues to be solved in the future for major national needs are discussed,which provided important clues and enlightenment for the research of Acidithiobacillus spp. in physiological metabolism,environmental adaptation and industrial and agricultural applications.

Key words: Acidithiobacillus, extreme environment, sulfur metabolism, iron metabolism, bioleaching
