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

We investigated the effect of peptone and (NH4)2SO4, used as nitrogen sources in a submerged medium, on the molecular weight and carbohydrate compositions of exopolysaccharides (EPSs) produced by the culinary-medicinal mushroom Pleurotus citrinopileatus. When (NH4)2SO4 was used instead of peptone, it yielded more specific EPSs, producing 32.80 mg EPS/g dry mycelial biomass, but small amounts of EPS and mycelial biomass. These nitrogen sources also resulted in the production of different net charged EPSs, according to crude fractionations on a DEAE Sepharose Fast Flow column. Purified EPSs were initially repurified by gel filtration chromatography, and the profiles indicated that a range of EPSs with different molecular weights were collected through the use of this strategy. Analysis of the carbohydrate composition of purified EPSs demonstrated that the main component produced by P. citrinopileatus in a glucose-(NH4)2SO4 medium, with an estimated molecular weight < 10 kDa, was rich in glucose (95.9%), and its structure could consist of glucan. Conversely, this mushroom produced diverse heteropolysaccharides (11.1-42.3% mannose, 6.3-80.3% glucose, 0.3-49.2% N-acetylgalactosamine, and 7.6-26.3% N-acetylglucosamine) in a glucose-peptone submerged medium. By applying various nitrogen sources in submerged medium, these results could be used to improve the possibility of obtaining molecules similar to those found in the fruiting bodies of the same mushroom species grown in conventional culture.
