“…7b) shows a peak at 1614 cm −1 that represents the COOH stretching vibration of alginate, while the peaks at 3450 cm −1 and 1086 cm −1 are related to the OH stretching vibration and the C O stretching vibrations of alginate, respectively. The band at 2924 cm −1 is assigned to the stretch vibration absorption of aliphatic C H from glucose units in alginate chains [29]. Moreover, two bands at 1732 cm −1 and 1418 cm −1 are attributed to the asymmetric and symmetric stretching vibrations of the carboxyl group of alginate molecule, respectively [30,31].…”

“…In addition, the peaks observed at 1406 and 1457 cm −1 were related to the symmetric stretching vibrations of carboxylate (COO − ) groups . The band at 2943 cm −1 was assigned to the stretching vibration absorption of CH amino acid units in the collagen chains . In the FTIR spectrum of collagen depicted in Figure (d), the band at 1587 cm −1 (amide II band) was attributed to the bending vibrations of NH in the amide group (CONH) .…”

“…Further CA immobilization studies onto the surface of various bacteria, including Bacillus pumilus, Micrococcus lylae, and Pseudomonas fragi, showed up to 50% catalytic activity after 30 days of storage (61). The successful observation of calcite precipitation and esterase activity from immobilized live P. fragi and B. pumilus cells to chitosan beads may eliminate the need for protein purification (47,49). The successful expression of Helicobacter pylori CA on the surface of E. coli (62) could lead to the advancement of immobilizing live bacterial cells with surface-expressed CA onto hydrogels for biomineralization of CO 2 .…”

“…To improve upon the stability of CAs for use in an industrial carbon sequestration setting, researchers have studied the immobilization of CA onto various inorganic (41)(42)(43)(44)(45) and biopolymer surfaces (46,76), which include enriched microorganisms (48,49), in addition to adhesion onto several matrices such as chitosan, alginate, and acrylamide (50,51). The immobilization of CA onto these materials is facilitated by the number of free hydroxyl groups and surface lysine resides of the particular isoform (52) (Figure 16.2).…”
