Notes on the List of Cultures

Explanation of Strain Data

Strains are listed alphabetically by genus and species and the corresponding information available for each is provided as follows:

• CPCC number;
• Available information pertaining to its collection, isolation, purification, identification (aka = also known as), and deposition;
• Relatives:
  • Some of the strains in CPCC are derived from strains also held in other private and public collections. This information is noted after “Relatives” in the description for each strain.
• Remarks (Rem:):
  • In the remarks, the code "A" indicates an axenic culture, "B" means the culture may contain bacteria, "F" means the culture currently has a fungal contaminant. Please note that the contamination status of any strain may change. Current status is best obtained from the Technical Curator. “L” means the culture is in liquid, “S” means the culture is on solid medium (plate or agar slant). If the cultures are maintained on agar slants and/or plates (“S”), then they may be ordered either on agar slants or in liquid medium. If the cultures are maintained in liquid (“L”), they may only be ordered in liquid medium. The majority of strains are maintained in liquid culture. This information may not be up-to-date, so please contact the Technical Curator for current information. Remarks may also include information on maintenance conditions and special culture requirements, ecology, toxicity, tolerance to heavy metals, toxin production, special characteristics and usages, etc.
• References and molecular sequence information are available upon request where indicated.

Identity of CPCC Strains

Each strain is assigned a unique accession number, which will never change. When the UTCC became the CPCC, the accession numbers remained the same (only the preceding acronym changed). However, it is possible that a new genus and species name may be assigned as taxonomic studies reveal a new identity for a particular strain. The name given to the culture by the depositor is listed here and alterations are made at the request of the depositor or when publications that are accepted by the scientific community require a change in name, or when edits to the taxonomy are adopted by Algaebase.org. Please notify us if a naming discrepancy is observed. Please use both the CPCC number and name when requesting cultures to ensure that the material is correctly identified.

As the CPCC does not have the resources to perform taxonomic studies on our strains we welcome investigators in this field to obtain any of the strains at half price for this purpose. Any subsequent information will be acknowledged and the species names modified accordingly.

CPCC Strains cited in Publications

Please inform us of any publications arising from the use of our strains and where possible supply us with a reprint. The CPCC strain number and species name must be used in your publications (e.g., CPCC 11 Chlamydomonas reinhardtii) in order to avoid subsequent confusion over the source and identification of the material. Also indicate that it was obtained from the Canadian Phycological Culture Centre at the University of Waterloo, Waterloo, ON, Canada. Your co-operation in this regard is vital to CPCC as we are creating a data bank of information on the strains in the CPCC. This information may also be used by potential granting agencies to evaluate proposals for funding. Providing us with molecular sequencing (e.g., NCBI-GenBank, EMBL-EBI, etc.) and special characteristics (e.g., biofilm, high lipid, toxin production, etc.) information would also be greatly appreciated, as it will broaden our knowledge of our strains.

CPCC Determination of Axenicity

The CPCC defines “axenic” as being without demonstrable bacterial and/or fungal contamination as demonstrated by inoculation onto sterility test plates. These sterility test plates consist of nutrient medium, yeast extract, peptone (or tryptone), glucose (or sucrose) plus agar and are monitored over the course of a 2-week period at room temperature.
