Abstract

Authors have found out that bamboo charcoal powder (BCP), which is prepared from bamboo
wastes by pyrolysis at low temperatures, is very useful as a carrier for the thermal stabilization of proteins. Hen
egg white lysozyme (HEWL) and α-chymotrypsin (CT) were effectively adsorbed onto BCP. The thermal
stability of BCP-adsorbed HEWL was strongly dependent upon the adsorption conditions such as solution pH,
ionic strength, and temperature. Moreover, writers have revealed the heat-resistant mechanism on the basis of
the structure of HEWL. Likewise, the thermal stability of BCP-adsorbed CT could be enhanced by selecting the
adsorption condition.
