“…Similar results have been reported previously . On the other hand, the V max values were decreased for both PGMA‐ and PGMA–NH 2 ‐immobilized laccases as compared to the free laccase, indicating a decrease in the substrate conversion rate . There are many reasons for the variations in these parameters after immobilization, such as conformational changes, decreased enzyme flexibility, or lower enzyme active site availability for the substrate due to the conformational rigidity caused by enzyme immobilization .…”

Enzymatic immobilization is a versatile alternative to improve enzyme stability and enable its reuse. In this study, the change in the immobilized enzyme properties due to the type of functional group on the carrier was evaluated. For that, monodisperse polymeric microspheres with two functional groups widely used in laccase immobilization—oxirane [poly(glycidyl methacrylate) (PGMA)] and hydrazide—were synthesized by dispersion polymerization to covalently immobilize the laccase Trametes versicolor. Using a response surface methodology, laccase immobilization was optimized for each microsphere type. As a result, laccase immobilization on PGMA carriers appears to broaden the pH and temperature ranges, storage stability, and reusability compared to free and hydrazide enzymes. These aforementioned characteristics indicate that PGMA microspheres could act as an ideal support for enzyme immobilization in biotechnological applications. © 2017 Wiley Periodicals, Inc. J. Appl.

“…The adeptness of fungal laccases in oxidizing a wide range of aromatic compounds makes them conspicuous determinants in the environmental bioremediation process [23]. Laccases from different microorganisms have been employed for biodegradation of PAHs, such as a yellow laccase from Leucoagaricus gongylophorus [24], CueO from Escherichia coli [25], and laccase from Trametes villosa [26]. Till now, prior studies had primarily focused on the degradation capacity of laccase determined by the shake flask method.…”

This study aimed to investigate the biodegradation of three distinct PAHs: Phenanthrene (Phe), Pyrene (Pyr), and Benzo[a]pyrene (BaP) by using fermentation broth from T. hirsuta culture medium. The results revealed that 2,5-xylidine ameliorates laccase production in T. hirsuta fermentation medium. After 6 days of incubation, T. hirsuta zlh237 fermentation broth (6-day-FFB) showed a higher degradation rate for three PAHs than 11-day fermentation broth (11-day-FFB). Final Phe, Pyr, and BaP degradation rates of 6-day-FFB were 89.35%, 85.92%, and 89.45%, respectively, on the 5 th day of incubation. The PAHs biodegradation rate of 6-day-FFB in natural soil samples were lower than in sterilized soil. The Phe, Pyr, and BaP degradation rates of 6-day-FFB were 54.49%, 46.76%, and 51.93% in sterilized soil samples, and 39.37%, 34.00%, 33.99% in natural soil samples, after 15 days incubation, respectively. The high-throughput sequencing analysis revealed that the 6-day-FFB altered the bacterial community structure and enhanced microbial biodiversity of contaminated soil. The PAHs-contaminated soils incubated with 6-day-FFB showed significant increase in well color development than the controls. Principal Component Analysis of Biolog data differentiated the effect of 6-day-FFB and sterilized 6-day-FFB on contaminated soils. It implied that T. hirsuta zlh237 restored the microbiological functioning of the PAHs contaminated soils.
