Thermal Stabilization of HEWL by Adsorption on Biochar | Chapter 11 | New Advances in Materials Science and Engineering Vol. 2
The heat stress tolerance of hen egg
white lysozyme (HEWL) was markedly enhanced by the adsorption of HEWL on bamboo
charcoal powder (BCP), which is a kind of biochar. HEWL was firmly adsorbed on
BCP even at high temperatures. The secondary structure of HEWL was altered to
some extent by the adsorption of HEWL on BCP. The remaining activity of
BCP-adsorbed HEWL exhibited more than 20% after the incubation for 30 min at
90°C although that of free one was hardly observed. Moreover, the half-life of
BCP-adsorbed HEWL was 13 min at 90°C while that of free one was 4 min.
