The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 1.2 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 1.4 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.3 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00066 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.34 SJR: 0.274 SNIP: 0.41 CiteScore™:: 2.8 H-Index: 37

SINOPSIS

The study of the physiological characteristics of the medicinal mushroom Trametes pubescens was conducted under submerged cultures, suggesting that the laccase activity was positively correlated with oxidative level and culture conditions. Mycelial biomass and laccase activity in medium I were higher than those in medium II, which indicated that laccase activity was correlated with mycelium growth. The enhancement in mycelial biomass presented the logarithmic increase at days 6−8 and the peak value on the day 12 after inoculation. During liquid cultivation, increases in the amounts of malondialdehyde, hydrogen peroxide, and ascorbic acid were observed. In addition, the higher activities of superoxide dismutase and total antioxidative capacity still could be detected during this period. However, better ability to restrain hydroxyl free radical and catalase had a negative influence on laccase activity. It was evident that the fungal strain T. pubescens was under oxidative stress during the laccase-producing process. When the concentrations of H2O2 and Fe2+ were 3 and 30 mmol/L, respectively, the laccase activity reached to its peak at 37.21 U/L after a 14-day incubation period. It was concluded that a relationship between laccase synthesis and antioxidative capability existed in fungal cells, which could be regulated by reactive oxygen.
