Laccase-immobilized tannic acid-mediated surface modification of halloysite nanotubes for efficient bisphenol-A degradation

Abstract

We report a simple tannic acid (TA)-mediated surface modification strategy for the fabrication of HNT-based efficient enzyme immobilization supports.

Immobilization of lipase on the modified magnetic diatomite earth for effective methyl esterification of isoamyl alcohol to synthesize banana flavor

“…3c, similar results were also observed in the immobilization time optimization that the enzyme loading improved with the time extension at the beginning 3 h, while the enzyme loading was fixed after 3 h. This phenomenon was similar to the previous reports (Bindu and Mohanan 2017). Increasing in relative activity could be attributed to the increase in lipase accumulation on the support surface while decreasing in the relative activity could be ascribed to the enzyme overcrowding that delay the substrate diffusion into the active site (Zhang et al 2019). As a result, 3 mg of added lipase with 3 h of conjugation time was the best combination for the enzyme immobilization on mDE-APTES.…”

Halloysite Nanotubes Decorated with Fe3O4 Nanoparticles and Tannic Acid for Effective Inhibition of E. coli Biofilm

“…The dried HNTs-M were grounded in the mortar and pestle for further use. The tannic acid modification of HNTs-M was done by mussel-inspired method . The reaction vessel containing the 250 mL of Tris buffer (pH 8.5) containing tannic acid (0.6%) was added with the HNTs-M (0.2%).…”

“…The tannic acid modification of HNTs-M was done by mussel-inspired method. 31 The reaction vessel containing the 250 mL of Tris buffer (pH 8.5) containing tannic acid (0.6%) was added with the HNTs-M (0.2%). This mixture is vortexed thoroughly and followed by ultrasonication by Sonics Vibra-Cell VC130 Ultrasonic Processor, power�130 W, frequency�20 kHz, and amplitude�40 μM (Sonics & Materials, Inc., Newtown, CT, USA) for 30 min.…”

Embedding low–cost 1D and 2D iron pillared nanoclay to enhance the stability of polyethersulfone membranes for the removal of bisphenol A from water

“…HNTs and Bentonite for BPA removal [34][35][36]. Tomul et al studied the efficiency of pillared bentonite for BPA removal by catalytic oxidation and adsorption [6].…”

“…Tomul et al studied the efficiency of pillared bentonite for BPA removal by catalytic oxidation and adsorption [6]. The results of the abovementioned studies [6,[34][35][36] revealed that functionalized nanoclays shown tremendous effect for the removal of organic phenolic compounds (BPA) from wastewater. PILC has opened new opportunities for MMMs fabrication and BPA removal by NF.…”
