The role of laccase and peroxidase of Lentinus (Panus) tigrinus fungus in biodegradation of high phenol concentrations in liquid medium

The integration of cyanide hydratase and tyrosinase catalysts enables effective degradation of cyanide and phenol in coking wastewaters

“…Many of them were based on the use of oxidative enzymes such as TYR or LAC, or whole cells producing these enzymes. In this way, phenol was degraded at concentrations of up to 600e800 mg L À1 by LAC from Trametes versicolor (Zhang et al, 2012;Wang et al, 2012), up to 940 mg L À1 by TYR from A. bisporus (Romanovskaya et al, 2009;Shesterenko et al, 2012), 1,298 mg L À1 by T. versicolor cultures (Ryan et al, 2007) and 30,000 mg L À1 by Lentinus tigrinus cultures (Kadimaliev et al, 2011). The concentration of phenol in the wastewaters degraded in this study (ca.…”

“…1,552 mg L À1 ) was thus among the highest ever used. Only the transformation by Lentinus tigrinus employed higher phenol concentrations but it was rather time-consuming, 6 days being necessary to achieve 90e96% degradation (Kadimaliev et al, 2011).…”

Evaluation by the Oxidase Activity of Xylotropic Macromycetes Causing White Decay

“…In this regard, the studies where an active producer of these enzymes was found, clarified a number of issues of enzyme synthesis [4] [5] and some results have even been applied to the industrial. However, fungi investigated in this direction constitute a small part of those known ones and Advances in Bioscience and Biotechnology some issues related to the synthesis regulating of some enzymes have not been clarified yet [6] [7] as well as producers with high biological activity is in the minority today.…”
