NOMENCLATURE

The scientific names of bacteria listed in the catalogue are in accordance with the presently accepted nomenclature in bacteriology (per April 1993). Names are valid only when listed in the "Approved Lists of Bacterial Names" (Skerman et al. 1980; reference 1300) as indicated by AL or when validly published since then by an original publication in the International Journal of Systematic Bacteriology (IJSB) or if published elsewhere by quotation in the lists of "Validation of the Publication of New Names and New Combinations Previously Effectively Published Outside the IJSB" as indicated by VP. All other names have to be considered as invalid and consequently should be identified as such only by using quotation marks.
Arrangement of strain data in this catalogue is based on the actual taxonomic developments. Nevertheless invalid names, validly changed names or synonyms have not been excluded.

To help all scientists to become familiar with the most recent developments in nomenclature, a list is compiled by the DSMZ and updated every two months covering all presently validly published names of bacteria and indicating all nomenclatural changes since January 1980. The list is available upon request as a hardcopy, on diskette or on-line via the Internet server.

The names of fungi and yeasts try to reflect current taxonomic practice including the recommendations published by the IUMS "International Commission on the Taxonomy of Fungi" (Microb. Sci. 3, 168-171 and 285-287, 1986; 5, 23-26, 1988; Mycopathol. 111, 75-83, 1990. In case of recent name changes or misidentification of strains a cross reference to the new designation is included and the former designation is included in the strain's history. No attempt is made to cover all synonyms.

ARRANGEMENT OF STRAIN DATA

• Corynebacterium ammoniagenes (Cook and Keith) Collins 1987 VP
  Scientific name of the species, followed by author(s) and year of publication. AL denotes the inclusion of this name in the Approved Lists, VP means it has been validly published since 1980.
• Basonym: Brevibacterium ammoniagenes
  The former name of the species until a new combination had been created, in that example by Collins in 1987. The basonym is not mentioned in the history of the strain.
• DSM No. 20306 = ATCC 6871, NCIB 8143, NCTC 2398
  DSM strain number followed by synonymous collection numbers.
• <- H. G. Schlegel <- K. Komagata <- ATCC <- NCTC <- J. V. Cook, 9.6.
  History of the strain before deposit into the DSM.
• Stool of infant (1307).
  Source of isolation followed by number of reference in brackets.
• Type strain (1300, 3233).
  If the strain is the type strain of the species this information is given together with reference number(s) in brackets. Two or three references are cited in the case of a new combination.
• Taxonomy/description (1306, 3233).
  If available, important references to taxonomic data are given under this heading (e.g. general description, DNA base composition, nucleic acid studies, chemotaxonomical data) together with the reference number(s).
• Murein: A31 (885).
  If known the murein (peptidoglycan) type of the strain is indicated by a short code specifically developed for the DSMZ catalogue. See key table to connect these codes with the Classification System of peptidoglycans (Schleifer and Kandler 1972).
• Produces 5'-inosinic acid (U.S. Pat. 3,268,415); L-isoleucine (U.S. Pat. 3,262,861); 5'-ribosyl phosphates of 8-azapurine derivatives (U.S. Pat. 3,296,089).
  Additional information on the strain followed by reference number(s) or patent number in brackets.
• (Medium 53, 30C)
  Culture medium and growth conditions which ensures good recovery and growth of the strain upon receipt (see List of Media). For special applications or experiments modifications of media and growth conditions may be required.
