Provided is a carbon monoxide (CO) dehydrogenase with increased oxygen resistance and/or enzyme activity, specifically, a mutant CO dehydrogenase with increased oxygen resistance and/or enzyme activity by mutating amino acid residues. The CO dehydrogenase may detoxify toxic carbon monoxide at room temperature and pressure by easily oxidizing carbon monoxide and converting the same into carbon dioxide, and may effectively oxidize carbon monoxide even in gas including oxygen. Furthermore, since it is possible to remove carbon monoxide, which is emitted in large quantities in industries such as petrochemical and steel industries, cigarette burning, household cooking, various boilers, and combustion, through cigarette filters, air purifiers, intake filters in household cooking equipment, gas boilers, etc. the CO dehydrogenase may be utilized in various ways.

The present disclosure provides a method for wet removal of sulfur dioxide by silicate bacteria-enhanced pulp. The method includes: treatment of ore waste residue, activation and domestication of silicate bacteria, preparation of pulp, removal of sulfur dioxide, and resource utilization of a desulfurization product. The present disclosure combines flue gas desulfurization with resource utilization of the ore waste residue, and improves a desulfurization efficiency of the method by the pulp and a utilization rate of ore waste residue resources through silicate bacteria. The present disclosure has a high desulfurization efficiency, simple production process, and low cost, and realizes the recycling of resources such as the ore waste residue, the sulfur dioxide, and silicon. The present disclosure has obvious economic and environmental benefits and broad prospects for use.

The invention provides for the optimal utilization of gas by a fermentation process, whereby the various components within the gas stream are separated to increase the efficiency of the microorganisms. The invention is capable of tailoring the composition of the gas being used by the fermentation process so as to enhance the production of various products. The invention is capable of applying such controlled separation and utilization of gas to produce different products in two parallel fermentation processes. The invention is also capable of applying such controlled separation and utilization of gas to produce one product in a first fermentation process, which may be converted to a different product in a second fermentation process. The invention is additionally capable of mitigating culture inhibition.
