Properties 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 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 کاملUltrasound-intensified laccase production from Trametes versicolor.
An efficient intermittent ultrasonic treatment strategy was developed to improve laccase production from Trametes versicolor mycelia cultures. The optimized strategy consisted of exposing 2-day-old mycelia cultures to 5-min ultrasonic treatments for two times with a 12-h interval at the fixed ultrasonic power and frequency (120 W, 40 kHz). After 5 days of culture, this strategy produced the hig...
متن کاملCHLORINE REMOVAL FROM pp’DDT BY LACCASE ENZYME PRODUCED FROM TRAMETES VERSICOLOR
As a member of phenoloxidase group of enzymes, laccase has been reported as to be quite efficient in oxidative degradation of various phenolics by some investigators. In this paper, effectivity of laccase enzyme produced from Trametes versicolor ATCC 200801 on dechlorination of pp’DDT in order to reduce its toxicity has been investigated. In experimental conditions used during enzymatic dechlor...
متن کاملBiogenic silver nanoparticles associated with silver chloride nanoparticles (Ag@AgCl) produced by laccase from Trametes versicolor
In the present study, semi-purified laccase from Trametes versicolor was applied for the synthesis of silver nanoparticles, and the properties of the produced nanoparticles were characterized. All of the analyses of the spectra indicated silver nanoparticle formation. A complete characterization of the silver nanoparticles showed that a complex of silver nanoparticles and silver ions was produc...
