Air contains a lot of pollutants and most of these pollutants are toxic. Carbon monoxide (CO) is one of the five primary pollutants, which together contributes more than 90% of global atmospheric pollution. Therefore, CO has been chosen for this analytical study. The main source of CO is the exhaust from automobiles only. In the present situation, the usage of motor vehicles rapidly expanded. The number of vehicles cannot be reduced but their emission (which is a cause for pollution) can be effectively controlled. In this direction, a model has been developed in this study to sense the level of carbon monoxide emitted from the automobiles. When the exhaust reaches a harmful level it sends the data about the vehicle number and the concentration of CO to the emission-testing centre (PC). As a result the government can take necessary action to seize the particular vehicle emitting more carbon monoxide than the permitted level.

In the ancient microbial Wood-Ljungdahl pathway, carbon dioxide (CO) is fixed in a multistep process that ends with acetyl-coenzyme A (acetyl-CoA) synthesis at the bifunctional carbon monoxide dehydrogenase/acetyl-CoA synthase complex (CODH/ACS). In this work, we present structural snapshots of the CODH/ACS from the gas-converting acetogen , characterizing the molecular choreography of the overall reaction, including electron transfer to the CODH for CO reduction, methyl transfer from the corrinoid iron-sulfur protein (CoFeSP) partner to the ACS active site, and acetyl-CoA production. Unlike CODH, the multidomain ACS undergoes large conformational changes to form an internal connection to the CODH active site, accommodate the CoFeSP for methyl transfer, and protect the reaction intermediates.

Diverse bacteria and archaea use atmospheric CO as an energy source for long-term survival. Bacteria use [MoCu]-CO dehydrogenases (Mo-CODH) to convert atmospheric CO to carbon dioxide, transferring the obtained electrons to the aerobic respiratory chain. However, it is unknown how these enzymes oxidize CO at low concentrations and interact with the respiratory chain.

The present work emphasizes the viability of methyl ester production, characterization, and utilization of third-generation biofuel from Chlorella vulgaris microalgae. The presence of methyl oleate (CHO) in the Chlorella vulgaris methyl ester (CVME) algae signifies the existence of higher oxidation stability and prone to peroxidation. The single-stage transesterified CVME algae contains majorly (C-H) functional group trailed by (C = O), (C-O), (O-CH), (C-O-C) with the elemental compositions of 66.
