At present, the global climate change is one of the biggest challenges in front of human race which results mainly from global warming due to an increased concentration of green house gases in the atmosphere. Among the major green house gases, Carbon dioxide and methane contribute maximum toward the global warming. To mitigate the global climate change the reduction in emission of green house gases is necessary. Microorganisms play a crucial role in the regulation and utilization of these gases. Bacteria can be employed in various ways to address the problem of global climate change through utilization of atmospheric green house gases. This article will present a comprehensive review of the approaches that can present better solutions to reduce the atmospheric green house gases, mainly, CO2 and methane by using bacteria. Recent advances in biofuel research, nanodevices and creation of engineered carbon eating bacteria are some of the novel approaches which can open the new doors to mitigate global climate change. | Utilizing bacteria to mitigate global climate change A review
