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

ABSTRACT

Tremella fuciformis is a natural edible and medicinal mushroom commercially available in Taiwan. In this study, the effects of initial pH, incubation time, and various media to optimize exopolysaccharide (EPS) production by T. fuciformis were evaluated in shake flasks and a bioreactor. The antioxidant properties were investigated. The results showed that using potato dextrose broth medium (pH 9) and a 48-hour incubation time in a shake flask was the most efficient condition from which to obtain maximum EPS. However, the quantity of EPS from different initial pH values (5−9) was not significantly different. Total polyphenol and β−glucan contents from every EPS sample (pH 5−9) were evaluated. T. fuciformis polysaccharides (10 mg/mL, pH 9) could scavenge 40.63% of 1,1-diphenyl-2-picrylhydrazyl radicals. The chelating abilities of ferrous ion of all extracts reached more than 80%. EPS extract from the initial pH value of 9 showed the highest reducing power among the other pH values (half maximal effective concentration = 5.97 mg/mL). The EPS from T. fuciformis was noncytotoxic to mouse skin fibroblasts (NIH/3T3), and survival rates were more than 100% using MTT assay. The samples were used to analyze the scavenging activity against oxidative damage induced by ultraviolet B radiation and hydrogen peroxide. The results showed the antioxidant activity occurred in a dose-dependent manner (P < 0.05). Furthermore, these findings prove that the EPS of T. fuciformis from submerged culture possess antioxidant properties and can be used as an alternative treatment for cell protection.
