A bio-augmented system with Methylosarcina sp. LC-4 immobilized on bio-carriers: Towards an integrated approach to mitigate and valorize methane emissions from landfills to biodiesel
Chemosphere. 2023 Aug 30;341:139992. doi: 10.1016/j.chemosphere.2023.139992. Online ahead of print.ABSTRACTBio-augmented systems based on methanotrophs are indispensable in curbing anthropogenic methane emissions from engineered landfills or dumpsites to curtail rising levels of greenhouse gases. Using a defined methanotroph culture immobilized on an inert material-based bio-carrier makes it possible to harness these methane emissions for creating value-added products, thus contributing to the circular bio-economy. The methane oxidation capacity of the model methanotroph Methylosarcina sp. LC-4, a prospective organism for ...

Energy generation from bioelectrochemical techniques: Concepts, reactor configurations and modeling approaches
Chemosphere. 2023 Aug 28:139950. doi: 10.1016/j.chemosphere.2023.139950. Online ahead of print.ABSTRACTThe process industries are playing a significant role in boosting the economy of any nation. But the ill-management of industries has been posing alarming threats to a once pristine environment. As a result, the untreated waste and wastewater discarded by many industries seemed to contain abundant organic matter. It is more likely that they disrupt the proper functioning of the water bodies by perturbing the sustenance of many species of flora and fauna occupying the different trophic levels. The simultaneous threats to h...

Study of synergistic effects induced by novel base composites on heavy metals removal and pathogen inactivation
Chemosphere. 2023 Aug 9:139718. doi: 10.1016/j.chemosphere.2023.139718. Online ahead of print.ABSTRACTThe green-collar strategies for nanomaterial synthesis with novel structural competencies have received significant attention in nanotechnology owing to their potential benefits. The utilization of silica nanoparticles for wastewater treatment through heavy metal ions remediation is the focal point of the present study. With this intent, silica was extracted from bagasse ash by the sol-gel method and modified using chitosan. Chemical and physical characteristics of silica(S), silica/Chitosan (SCs), were reckoned through X-...
