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

Краткое описание

Approximately 670 million broiler chickens and 43 million turkeys are produced in North Carolina annually, generating wastes that are causing environmental problems and concerns among residents. These waste products can be used as substrate for growing specialty mushrooms. Mushroom farming can enable farmers to obtain additional crops (mushrooms), while bioconverting the agricultural wastes to more environment friendly products such as organic fertilizers. Agaricus brasiliensis and A. subrufescens are culinary−medicinal mushrooms currently produced in the US. These mushrooms can be alternative crops generating high income in the place of tobacco for the North Carolina farmers.
Various combinations of sawdust, poultry litter, and cotton waste were made and loaded in 3 × 12 cm glass test tubes. The tubes containing substrate were sterilized at 121 °C for 1, 2, or 3 hours. A set of 8 tubes per substrate combination was inoculated with A. brasiliensis or A. subrufescens. Similar substrate combinations were pasteurized at 90 °C for 48 hours and then inoculated.
Growth rates of each substrate combination/heat treatment were determined, based on the time for achieving total substrate colonization in each tube. To determine the effect of nutrient supplementation on mycelia growth and development, the substrate combination/heat treatment that performed best in the above treatments was supplemented with wheat bran or millet or combinations of both at 10, 15, and 20% proportions. Non-supplemented substrate served as a control.
Substrate combinations containing cotton waste did not show significant growth and development in either A. brasiliensis or A. subrufescens. Sterilization was ineffective at suppressing contaminants in any substrate combination that had poultry liter. Pasteurization of poultry litter containing substrates at 90 deg;C for 48 hours was sufficient to suppress contaminant. Poultry litter and sawdust in a 1:1 ratio proved to be the best substrate for supporting mycelia growth, where total colonization took an average of 15 days, reaching primordial formation in 60 days. Both fungi responded well to nutrient supplementation, showing an average of 81.5% increase in mycelia growth over the control. In both fungi tested, there was consistent increase in colonization rate as supplementation increased; however, incidence of contaminants increased with the increase of supplementation.
Further work on optimization of substrate pretreatment and environmental conditions that best support the development of primordial through mature fruit body formation in both fungi are currently being researched.
