The relationship between lignin peroxidase and manganese peroxidase production capacities and cultivation periods of mushrooms.

Xu JZ, Zhang JL, Hu KH, Zhang WG - Microb Biotechnol (2012)

Bottom Line: The results show that there are close relationships between LiP- and/or MnP-secretory capacities and the cultivation periods of mushrooms.This study provides the first evidence on the imitate relation between the level of secreted LiP and MnP activities and cultivation periods of mushrooms with non-laccase activity.Our study has significantly increased the understanding of the role of LiP and MnP in the growth and development of mushrooms with non-laccase activity.

The LiP and MnP activities and the dry weights of 10 strains after 7 days incubated in MYPGB at 24°C and pH 7.0 with shaking (100 r min−1). Each value represents mean with standard error of three replicative experiments. The standard errors are shown as bars.

fig02: The LiP and MnP activities and the dry weights of 10 strains after 7 days incubated in MYPGB at 24°C and pH 7.0 with shaking (100 r min−1). Each value represents mean with standard error of three replicative experiments. The standard errors are shown as bars.

Mentions: The LiP and MnP activities in culture supernatants of 10 strains at the seventh day are show in Fig. 2 (shown as bar graph). Both LiP and MnP were detected in group I by spectrophotometry. Only MnP was obviously detected in group II, and both LiP and MnP were difficult to detect in group III. The results of quantitative analysis were coincident with the results of qualitative analysis. Among these 10 strains, Agrocybe sp. showed the highest level of LiP and MnP activities, nearly 0.382 ± 0.016 U ml−1 and 0.627 ± 0.016 U ml−1 respectively. However, the LiP activities of P. nebrodeusis, G. frondosa, P. nameko and L. irina were extraordinary low, nearly 0.005 ± 0.021 U ml−1, 0.003 ± 0.012 U ml−1, 0.006 ± 0.029 U ml−1 and 0.002 ± 0.008 U ml−1 respectively. The MnP activities of P. nameko and L. irina were also very low, nearly 0.01 ± 0.016 U ml−1 and 0.005 ± 0.013 U ml−1 respectively. The activities of MnP were higher than the activities of LiP for every mushroom strain (Fig. 2).
