Abstract: A method of producing sulfuric acid can include: obtaining a microbial culture that produces sulfuric acid; placing the microbial culture in a bioreactor in an aqueous environment; introducing an aqueous, liquid or gaseous sulfur supply into the bioreactor; and culturing the microbial culture with the sulfur supply sufficiently so that sulfuric acid is produced. The sulfur supply can be from aqueous or gaseous sulfur dioxide and/or dihydrogen sulfide, or sulfurous acid. The microbes are any microbes that processes sulfur, such as natural microbes that processes sulfur, genetically modified microbes that processes sulfur, cultivated microbes en.) that processes sulfur, purchased microbes that processes sulfur. The microbes may also include other type of microbes that facilitate culturing of the sulfuric acid producing microbes. The sulfuric acid can be produced at ambient conditions. In one aspect, the process is a batch process or a continuous process.
