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

Cordyceps militaris is a highly valued edible and medicinal fungus because of its production of various metabolites including adenosine, cordycepin, and N6-(2-hydroxyethyl)-adenosine. Fruiting bodies of this fungus have been used successfully in industrial production and widely as a substitute for Ophiocordyceps sinensis (syn. C. sinensis) in traditional Chinese medicine and health supplements. Strain degeneration occurs with high frequency during the subculturing and preservation of C. militaris strains, which leads to significant losses during industrial production. In this study, we evaluated the effects of different strain preservation methods on fruiting body growth and metabolite production. We found that strain degeneration affects not only fruiting body differentiation but also metabolite production, and suitable preservation methods can avoid degeneration. Preservation in sterile water has a similar effect as cryopreservation in liquid nitrogen at -196°C with regard to maintaining the characteristics of C. militaris strains for at least 1 year, and it is a practical and satisfactory method for preserving C. militaris strains that can be used in factories. Ultracold freezing at -80°C is not suitable for this fungus. Lyophilization, which causes C. militaris strains to retain their inherent characteristics and avoid degeneration, is suitable for long-term preservation (at least 4 years). This study provides practical preservation methods for C. militaris strains over the short and long term and will be helpful to achieve stable and superior-quality production of C. militaris fruiting bodies.
