Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
A new actinomycete strain, designated US80 and producing antimicrobial activities against Gram-positive and Gram-negative bacteria and fungi, was isolated from Tunisian oasis soil. Cultural characteristic studies strongly suggested that this strain belongs to the genus Streptomyces. The nucleotide sequence of the 16S rRNA gene (1517 pb) of Streptomyces sp. strain US80 exhibited close similarity (97–98%) with other Streptomyces 16S rRNA genes. Similarity of 98% was obtained with the 16S rRNA gene of Streptomyces roseoflavus, which produces the aminoglycoside antibiotic flavomycin. Study of the influence of different nutritional compounds on production of bioactive molecules showed that the highest antimicrobial activities were obtained when glucose at 1% (w/v) was used as sole carbon source in the presence of magnesium. Extraction of fermentation broth of Streptomyces sp. strain US80 and various separation and purification steps led to isolation of three pure active molecules. The chemical structure of these three compounds, named irumamycin (1a), X-14952B (1b) and 17-hydroxy-venturicidin A (1c), was established on the basis on their IR, ESI-MS, 1 H and 13 C/APT NMR data and by comparison with reference data from the literature.
