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

Mycelium of Ganoderma lucidum (W.Curt.:Fr.) Lloyd grew on the surface of molasses to form mycelial mats after about 12 days. When the mycelial mats became older, the color changed to a darker hue and wrinkled. It took about 9 days for the mycelium of G. tsugae Murrill to cover the whole surface of the molasses. Mycelial mats of G. tsugae were soft, and the old mycelia turned to yellow in color. Harvesting three pieces of mycelial mats of G. lucidum was enough to get 0.96 g of dried biomass. For G. tsugae, the mycelial mats were lighter. On wheat grains, the mycelium of G. lucidum needed 20 days to permeate throughout the grains. The mycelium of G. tsugae needed only 15 days. Both Ganoderma species produced primodia for approximately 65 days, and the mature basidiocarps were formed in about 100 days. The pH of extracts from both fungi became less acidic when harvested after longer periods. All the separation spots of the samples had an Rf value below 0.92. The TLC method detected the presence of triterpenoids in the extract. The different concentrations of thymol salt were used to obtain the standard curve through HPLC method. The values of triterpenoid concentrations, which refer to the peaks as P1, P2, P3, P4, P5, and P6 in the samples, were calculated based on this standard curve. P1, was obtained in every stage of incubation. P3 and P6 were detected only in the fruiting body, whereas P2, P3, P4 were the major triterpenoids of the mycelium. The highest triterpenoid production was found after 110 days; the fruiting body stage of G. tsugae is P5 with 1212.00 μg/mL. G. lucidum showed triterpenoid concentration and derivatives six times higher than G. tsugae.
