Diversity of laccase genes from basidiomycetes in a forest soil
Fungal oxidative exo-enzymes lacking substrate specificity play a central role in the cycling of soil organic matter. Due to their broad ecological impact and available knowledge of their gene structure, laccases appeared to be appropriate markers to monitor fungi with this kind of oxidative potential in soils. A degenerate PCR-primer pair Cu1F/Cu2R, specific for basidiomycetes, was designed to...
متن کاملOptimization of laccase production from Trametes versicolor by solid fermentation.
The regulation of culture conditions, especially the optimization of substrate constituents, is crucial for laccase production by solid fermentation. To develop an inexpensive optimized substrate formulation to produce high-activity laccase, a uniform design formulation experiment was devised. The solid fermentation of Trametes versicolor was performed with natural aeration, natural substrate p...
متن کاملProperties of crude laccase from Trametes versicolor produced by solid-substrate fermentation
A low-cost process for the production of laccases is necessary for a sustainable enzymatic wastewater treatment. Therefore, it is necessary to establish an easy and low-cost procedure for the production of laccase. In the present study the properties of crude laccase from Trametes versicolor produced by solidsubstrate fermentation is investigated. The application of the enzyme for dye decoloriz...
متن کاملPotential of solid-state fermentation for laccase production
Solid-state fermentation (SSF) processes involve the growth of microorganisms (typically fungi) on a solid material in the absence or near absence of free-flowing water. The wide range of solid materials used in SSF can be classified into two great categories: inert (synthetic materials) and non-inert (organic materials). The former only acts as an attachment place for the fungus, whereas the l...
متن کاملIsolation and Screening of Laccase Producing Basidiomycetes via Submerged Fermentations
Approximately 10,000 different types of dyes and pigments are being used in various industrial applications yearly, which include the textile and printing industries. However, these dyes are difficult to degrade naturally once they enter the aquatic system. Their high persistency in natural environment poses a potential health hazard to all form of life. Hence, there is a need for alternative d...
