Title: Production of Bjerkandera adusta’s ligninolytic enzymes on lignocellulosic substrates by solid state fermentation
Author: Belhamiche Nabila, Duchiron Francis, Benallaoua Said
Lignin is extremely recalcitrant to degradation.The white-rot fungi produce a array of extracellular oxidative enzymes that synergistically and efficiently degrade lignin such as laccase (Lac), manganese – peroxidase (MnP), and lignin peroxidase (LiP). The demand of these enzymes has increased in the recent years due to their potential in several industrial and biotechnological processes (detoxification of industrial effluent that contains dyes, phenols and others xenobiotics, biobleaching of Kraft pulp, denim washing, bioremediation). Production of enzyme from microbial sources is a costly affair and the only alternate to minimize the production cost in the use of inexpensive raw materials. The utilization of agro-industrial residues in this aspect is much appreciated due to their low cost and ease in availability. Adopting solid-state fermentation for enzymes production may add to the benefit of reducing the production costs. This work was carried out to study the ability of a fungus, isolated from an Algerian forest, to produce extracellular ligninolytic enzymes.
