Applications of Ligninolytic Enzymes from a White-Rot Fungus Trametes versicolor

摘要

The growing concern over the pollution issues by the rapid industrialization has posed a serious problem forcing researchers around the world to seek alternative eco-friendly technologies. Textile, pulp and paper industries discharge a huge quantity of waste in the environment, and the disposal of this waste is an immense problem. To solve this problem, work has done to discover such a biological process, which can detoxify these wastes and is not damaging the environment. Lignocellulosic agro-wastes comprising over 60% of the existing plant biomass are the potential renewable resources for bio fuels, bio fertilizers, animal feed, bioremediation and chemical feed stock. Trametes versicolor is one of the extra cellular, non-specific and efficient ligninolytic enzymes producers with high activities as secondary metabolites under optimum growth conditions, especially lignin peroxidases (LiPs), manganese peroxidases (MnPs) and laccases. Laccases use oxygen and produce water as by product. They can degrade a range of compounds including phenolic and non-phenolic compounds. They also have capability to detoxify a range of environmental pollutants. The present review therefore aims to bring out a comprehensive analysis of available biological agent which can replace the present highly polluting chemical processes for effluent treatment from pulp and paper industries, textile industries, food industries, bio remediation and bioethanol production.
