Abstract

Natural gas is chemically defined as a mixture of light paraffinic hydrocarbons which, at room temperature and atmospheric pressure, remains in the gaseous state. It is an odorless and colorless gas, non-toxic and lighter than air. The composition of natural gas can vary widely, but methane (CH4) is the main component (80-95%), also presenting carbon dioxide (CO2) contents. One of the major sources of natural gas production occurs in the oil extraction process where large volumes of natural gas are released. However, the release of gases (CH4 and CO2, mainly) is considered to be one of the main causes of global warming and climate change, although the accentuated uses of fossil fuels and changes in land use are also among the main causes. Given this scenario, the need arises to transform natural gas into other products, aiming at mitigating and generating products with higher added value. In this sense, there are some studies focusing on the microbial sequestration of CO2 and CH4, but not on the microbial conversion of both gases into bioproducts. To do so, a microbial consortium involving algae and bacteria can be used. Together, these microorganisms could rapidly metabolize high concentrations of CO2 and CH4, turning them into valuable bioproducts. (AU)
