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

Cordyceps nutans Pat. is an entomopathogenitic Ascomycete belonging to the family Clavicipitaceae and is parasitic on hemipteran insects. Very few investigations have been made with this fungus. C nutans grows very slowly. Thus, further evaluation of culture conditions was necessary. In this research, we examined optimum temperature and pH for mycelial growth of C. nutans. In order to find the optimal culture temperature for growth, three strains were incubated at 5, 10, 15, 20, 25, 30, and 35 °C in darkness for 3 months, with six repetitions. Seven initial pH conditions of the media were adjusted by using 1 N HCl or KOH, and set at every 1.0 pH level from 5.0 to 11.0. Cultures were incubated at 25 °C for 3 months in replicates of six. Mycelial growth was observed at 10—25 °C and was greater at 20 and 25 °C. At 5,30, and 35 °C, mycelial growth was not observed in any of the strains. Mycelial growth was observed at pH levels from 6.0 to 11.0 and not observed at pH 5.0. The overall tendency was that the strains grew relatively well in neutral to weak alkaline pH levels (pH 7.0∼9.0) compared with acidic pH levels, but colonies were sparse.
