Enzymes Encapsulation within Calcium Alginate-clay Beads: Characterization and Application for Cassava Slurry Saccharification

Removal of crystal violet dye by adsorption using bentonite – alginate composite

“…The R-O-R stretching for alginate is 1030 cm −1 and for bentonite is 1020 cm −1 , shifted to 1047-1091 cm −1 for all composites. The shift in the peak for COO − is indicated the electrostatic interaction between the negative charge carboxyl group of sodium alginate and the positive charge on the surface of bentonite [30][31][32]. Thus, the FTIR spectra of sodium alginate-bentonite composite confirmed the interaction between alginate and bentonite.…”

“…The adsorption isotherm study was conducted in a batch process at three different temperatures (30,50, and 70°C). The adsorption isotherm study was carried out by adding various amounts of adsorbent (0.1-1 g) into a series of Erlenmeyer flasks, each containing 50 mL of crystal violet dye solution with an initial concentration of 300 mg/L.…”

Enzymatic hydrolysis of starch into sugars is influenced by microgel assembly

“…Enzymatic immobilization is widely studied area to replace the use of free enzymes that have a number of disadvantages such as high cost and low stability. The technique of enzymatic immobilization makes it possible to separate enzymes within the products produced through the biochemical process and can be reused in several cycles, because they are retained in matrices or covalently attached to some surface [24] .…”

Immobilization of Low-Cost Alternative Vegetable Peroxidase (Raphanus sativus L. peroxidase): Choice of Support/Technique and Characterization

“…In the same way, other enzymes were immobilized on coconut fiber [ 36 , 37 , 38 , 39 ], an important bio-residue of world agribusiness [ 40 , 41 ]. Calcium alginate microspheres also were used as organic support for enzyme immobilization due to be material of easy synthesis, inexpensive and non-toxic [ 42 , 43 , 44 ]. Inorganic supports of distinct chemical natures have been applied for enzymes immobilization, such as iron hydroxyl oxide [ 45 ] and silica [ 31 ].…”
