Optimization 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 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 کاملChitosan multiple addition enhances laccase production from Trametes versicolor.
Chitosan multiple addition strategy was developed to improve laccase production from Trametes versicolor cultures. The optimized multiple addition strategy was carried out by two-time addition of 0.1 g L(-1) chitosan to a 2-day-old culture media, with 24-h interval between the treatments. Under these conditions, laccase activity of 644.9 U l(-1) was achieved on the seventh day and laccase produ...
متن کاملOxidation of Endocrine Disrupting Chemical by Trametes versicolor Laccase
There is longstanding environmental concern regarding endocrine disrupting chemicals and wastewater treatment facilities’ inability to remove them. Estrogens in particular, including 17 β-estradiol, 17 α-ethynylestradiol, and bis-phenol A, have been reported to depress cortisol levels and cause development of intersexual gonads in fish, along with various additional disruptions to the endocrine...
