Biotechnological Processes as Part of a Carbon Capture and Utilisation Strategy in the Oil and Gas Sector: A Case Study in a Natural Gas Treatment Plant in Libya
… combined with renewable hydrogen in biological processes to produce approximately 2,090, 4033, and 826 t/d of synthesis methane, acetic acid, and polymers, respectively. These processes could add up to 13% of methane gas to the natural gas product stream or acetic acid, and polyhydroxyalkanoates …

Experimental and computational studies of receptor-mediated cell detachment in shear flow
… a central phenomenon in many physiological and biotechnological processes. Mechanical strength of specific adhesion is generally presumed to be related to chemical affinity of receptor/ligand bonds, but no experimental study has been previously directed toward this issue. I investigate the …

Halogenated aliphatic and aromatic aerobic biodegradation via direct metabolism and cometabolism: batch and continuous tests
In this thesis the application of biotechnological processes based on microbial metabolic degradation of halogenated compound has been investigated. Several studies showed that most of these pollutants can be biodegraded by single bacterial strains or mixed microbial population via aerobic direct …
