In this study, hydrolytic and oxidative activities of enzymes isolated from halophilic microbes were characterized and applied for biomass utilization. First, lipase from Micrococcus luteus, and peroxidase and laccase from Pseudoalteromonas phenolica and Pseudoalteromonas peptidolytica were selected and their catalytic

Numerous efforts have been made to remove emerging trace organic contaminants, such as pharmaceuticals and personal care products (PPCPs). This study examined the removal of N,N-diethyl-m-toluamide (DEET) by Trametes versicolor laccase and its laccase-mediator systems. Experimental results showed that DEET

We report the functionalization of multi-walled carbon nanotube (MWCNT) electrodes by oxidative electropolymerization of pyrrole monomers bearing pyrene and N-hydroxysuccinimide groups. Both polymers were applied to the immobilization and electrical wiring of Trametes versicolor laccase via chemical grafting or non-covalent

What is the pH optimum of Product L2157, Laccase from Rhus vernicifera?
1 answer-
Our own assay is performed at pH 6.5. One publication (Casella et al., J. Inorg. Biochem., 100, 2127-2139 (2006)) gives pH 6.5 as another value for the laccase from this species, with a range for enzyme activity of 4.3 to 9.

My solution of Product L2157, Laccase from Rhus vernicifera, isn't clear. Is this normal?
1 answer-
Yes. L2157 is a crude acetone powder, and can contain other proteins, enzymes, and cellular debris. A suspension may be prepared in 100 mM potassium phosphate buffer, pH 6.5, by homogenization with a hand-held homogenizer for 10 minutes. This preparation may then be centrifuged; the laccase activity will be present in the supernatant.
