JF International Journal of Systematic and Evolutionary Microbiology, VO 33 IS 2 SP 321 OP 324 DO https://doi.org/10.1099/00207713-33-2-321 PB Microbiology Society, SN 1466-5034, AB A new species of bacteria is described, for which we propose the name Streptomyces sulfonofaciens. This organism produces a new β-lactam antibiotic, SF-2103A, which is a carbapenem compound. S. sulfonofaciens is characterized by its red spore mass, spores with smooth surfaces in straight chains, nonchromogenicity, and carbon utilization pattern. The type strain of S. sulfonofaciens is strain SF-2103, which has been deposited in the American Type Culture Collection as strain ATCC 31892., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/00207713-33-2-321
