“…Phanerochaete chrysosporium is the most intensively studied strain of white rot fungi that produces extracellular enzymes responsible for the degradation of pollutants (Bumpus et al 1985;Glenn and Gold 1985;Vazquez-Duhalt et al 1994). This fungus was also found to degrade a wide spectrum of organic pollutants (Glenn and Gold 1983;Kirk et al 1976;Pal et al 1997), during which the peroxidases were believed to play a key role. In addition, trace quantities of H 2 O 2 , VA and other chemicals are produced by the fungi, along with enzymes essential to regulating the enzymatic reactions, providing electron acceptors and mediators (Khindaria et al 1995;Tien and Kirk 1988;Wariishi and Gold 1989).…”

The removal of 17β-estradiol (E2) by white-rot fungus Phanerochaete chrysosporium cultured in classic Kirk or potato medium was systematically investigated. Results demonstrated that E2 can be efficiently removed regardless of culture media type. However, the reaction intermediates and transformation pathways varied in different media. Estrone (E1) and estriol (E3) were sequentially generated as intermediates in the potato medium, but these intermediates were absent in Kirk medium. Such results were found to correlate to the peroxidases produced in Kirk medium. These enzymes catalyzed one-electron oxidation of E2 to form radicals that can undergo oxidative coupling. Similar enzymes were not detected in the potato medium, thus E2 underwent in vitro oxidation to form E1 and E3 sequentially. Adding glucose to the potato medium further accelerated such processes. The findings in this study provide insights into estrogen reactions mediated by P. chrysosporium and for potential development of biodegradation methods to reduce estrogen contamination levels.

A 20-kHz intensity ultrasound was used in the extraction of iota-carrageenan from Eucheuma denticulatum seaweed by using water as solvent. In a simplified extraction procedure, the seaweed particle size of 0.7125E-03 m, 1.2E-3 m, and 1.7E-03 m diameter were studied at different ultrasonic amplitude levels, ranging from 2.08E-06 to 6.4E-06 m and the temperatures from 30 to 60 °C. The maximum iota-carrageenan yield obtained was 57.2 %. This study suggested that ultrasound intensity employed reduced the extraction time required and improved the yield of iota-carrageenan by 6 %. The particle diameter variation during the extraction was found to be a linear
