In recent years, pollution by chemicals including difficultlydecomposed organic substances (POPs) increasingly created by
human beings, causing a lot of implications for human health and the
environment. In such developing countries as Vietnam, the use and
discharge of chemical waste in agriculture, medicine, industry and
other manufacturing sectors without ability to be controlled has caused
serious consequences to the environment and humans. In addition,
herbicides containing dioxin in existence by the wars after more than
40 years and the nature of dioxins formed during the process of
industrial development still continues to cause more serious
consequences for the ecological environment and people in Vietnam.
Vietnam is a tropical country of biodiversity in the top 10
of the world, especially microbial diversity. There are many
species of microorganisms with differently-synthesized
enzymes; two of which are oxidoreductive and peroxidase
enzyme having included many high performance applications in
the fields of economy and protecting human health. Being not
only high-activity laccase but also capable of strong activity,
just together with liberal oxygen as well as the help of fastening
substance or fastening systems (mediator). Then this laccase has
been in the greater consideration than any other.
