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

During the cultivation of Pleurotus ostreatus on wheat straw and distillery effluent containing substrate, the primordia exhibited very low hemagglutinating activity. However, the hemagglutinating activity of the matured fruiting bodies and vegetative mycelium at harvesting time reached extremely high values, 32,051,282 and 69,930,069 U/mg, respectively. Four fractions of proteins (3.5−105 kDa) from the matured fruiting bodies and five fractions of proteins (125, 110, 69, 8, and 1.5−2 kDa) from the vegetative mycelium extract with lectin activity were obtained after gel chromatography through the column Toyopearl HW-55F. N-acetyl-D-glucosamine and N-acetyl-D-galactosamine were the most potent inhibitors of hemagglutinating activity of fraction I (0.19 mM) from the fruiting body extract. Galactose exerted the highest inhibitory effect toward lectins in other fractions at concentrations of 1.56−3.125 mM. Unlike the fruiting body lectins, the mycelial lectins displayed a predominant specificity toward mannose. CuCl2 and MgCl2 dose-dependently inhibited the lectin activity of mycelial fraction V. On the contrary, the hemagglutinating activity of this fraction was doubled in the presence of 5 and 10 mM MnCl2. The lectin activity of fractions II and V was halved in the presence of 5 mM EDTA, whereas 10 mM β-mercaptoethanol sharply decreased the hemagglutinating activity of fractions II-IV and completely inhibited the activity of fraction V, indicating the presence of Ca and cystine, respectively, in carbohydrate-binding centers of lectins.
