“…Numerous studies have investigated immobilizing CA onto a solid medium in order to increase its lifespan, particularly by minimizing exposure to denaturing conditions that may exist in an industrial carbon sequestration scenario (Cheng et al, 2008;Ozdemir, 2009;Sharma et al, 2011;Vinoba et al, 2012Vinoba et al, , 2011aWanjari et al, 2012;Yadav et al, 2011Yadav et al, , 2010. With particular relevance to this study, BCA immobilized within polyurethane foam preserved 100% activity over 45 days when stored in Tris buffer at ambient conditions in comparison to free BCA that lost its activity over the same period at 4 • C (Ozdemir, 2009).…”
