Fig.1. SDS-PAGE analysis of AE5 mutant strain CotA . SDS-PAGE was used to analyze the expression of CotA. Recombinant vectors pHJ5 transformed into BL21 (DE3) competent cells and induced by 0.1 mM IPTG in LB medium for 20 h at 16 ℃ , respectively. All the samples were analyzed by SDS-PAGE, and the protein was stained with Coomassie Blue in the gel. Lane M, protein marker.

Laccase（Bacillus）
Lignin peroxidase (LiP), phenoloxidases (laccases, tyrosinases), manganese dependent peroxidase (MnP) are the three enzymes commonly employed ligninolytic enzymes which are mainly involved in degrading lignin and analogue PAHs. Various researches have revealed that the mechanism of oxidation of PAHs by fungi ligninolytic enzymes is similar to the degradation of nonphenolic lignin.In vitro,laccases has activity towards 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) (ABTS), 2,6-dimethoxy-phenol, and guaiacol.

We changed the temperature and the concentration of the inducer. The figure above clearly shows that the target protein induced in LB medium is present in the supernatant (Fig. 1).
