More Electronic Resources for the Cyanobacteriologist

The number of world wide web sites having some relation to cyanobacteria, more than 1700 at last count, has grown far beyond the abilities of anyone to comprehend them all. Most sites, however, merely mention cyanobacteria, either as part of a description of a person's research interests, as part of a class syllabus, etc. Some sites, of more general interest, are given below. The list must be considered only a sampling of what is available.

CCAP SITE: Homepage of the Culture Collection of Algae and Protozoa, centered at the Windermere Laboratory, U.K. Provides a searchable on line description of strains held by the collection [see below]. Also contains recipies for growth media and instructions on how to order strains. http://wiua.nwi.ac.uk/ccap/ccaphome.html

CDAC SITE: Homepage of the Czechoslovak Database of Algae and Cyanobacteria. http://www.bdt.org.br/bdt/msdn/ccala/

UCMP BACTERIA SITE: The University of California Museum of Paleontology has an online collection of articles and pictures of bacteria, including many entries on cyanobacterially related subjects. http://www.ucmp.berkeley.edu/bacteria

PHOTOSYNTHESIS SITE: Arizona State University, Departments of Botany and Chemistry and Biochemistry run a site devoted to photosynthesis. It includes an extensive directory of e-mail addresses and list of upcoming meetings. http://Photoscience.La.Asu.Edu/Photosyn

CYANOSITE: provides useful protocols and other matters cyanobacterial, including directories of cyanobacteriologists and back issues of this newsletter. http://WWW-Cyanosite.Bio.Purdue.Edu

CYANOBASE SITE: Information regarding the Synechocystis PCC 6803 genome [see NEWS] and much else. Reports analysis of the currently available sequence and permits similarity search with sequences provided by visitors. Includes access to many if not all known cyanobacterial sequences and a search engine to help you find what you want. Displays a circular map of the genome and phylogenetic trees based on several gene sequences. Provides links to many other databases with prokaryotic sequences. http://www.kazusa.or.jp/cyano/cyano.html

TOXIC CYANOBACTERIA SITE: Houses a bulletin boards for announcements, informational entries (including graphics) on microcystins, anatoxin, nodularin, protein phosphatases, and Microcystis aeruginosa, and a debate on the merits/risks of ingesting Super Blue Green Algae (Aphanizomenon flos-aquae). Provides links to two related discussion groups: Phycotoxin and Cyano-tox. http://Luff.Latrobe.Edu.Au/~BotBML/Cyanotox.Html

RRNA SITE: A compilation of ribosomal RNA sequences, including 38 of cyanobacterial origin. Makes available a program to facilitate construction of trees, to align multiple sequences, and to draw secondary structures. http://www-rrna.uia.ac.be/

CYANOBACTERIA INTERNATIONAL SITE: I haven't figured this one out yet, except to realize that it hasn't anything to do with cyanobacteria as we know them. The site collects literature from Cyanobacteria Publications which, by its own description, conducts "a gyrovague experiment operating upon the chromosomes of beauty and information." http://www.thing.net/~grist/homecyan.htm


Matters Arising

The Proceedings are now available from a workshop entitled TOXIC CYANOBACTERIA: CURRENT STATUS OF RESEARCH AND MANAGEMENT. The workshop, held March, 1994 in Adelaide, Australia, covered various aspects of concern to the researcher and manager of water quality, including monitoring and analysis, health effects and risk assessment, control and removal of toxins, and management issues. The proceedings include contributions from Wayne Carmichael, Geoff Codd, Ian Falconer, Ken-ichi Harada, Gary Jones, Mick Pearson, and Shun-Zhang Yu. The cost of the proceedings is AUS$50 (check should be payable to "Workshop Proceedings").

Culture Collection Grows with Strains

Culture collections, like the strains they collect, are a product of evolution. The Culture Collection of Algae and Protozoa (CCAP) now maintains about 2000 algae and protozoa, of which more than 200 are cyanobacteria. This collection originated from strains isolated by Ernst Georg Pringsheim and his collaborators, Victor Czurda and Felix Mainx. When Pringsheim moved to England, his collection went with him and was eventually taken over by E.A. George at Cambridge University in 1947. In 1986 the collection was divided, freshwater algae and all protozoa going to the Institute of Freshwater Ecology (IFE) Windermere Laboratory at Ambleside and marine algae going to Dunstaffnage Marine Laboratory (DML) at Oban.

Strains are available for a fee of 21 per 10 ml for academic institutions. The strain list can be searched at the CCAP web site (see above). Alternatively, hard copies of the Catalogue are available for 7.00. A list of freshwater cyanobacterial strains can be obtained by anonymous FTP at the site Cyanonew@Servax.Fiu.Edu (password: Bluegreen). Download CCAP-CB.Asc (pure text).

The CCAP also holds the Fritsch Collection of Illustrations of Freshwater Algae, some 500,000 published figures of taxonomic or floristic significance. They are taken from over 15,000 works and cover over 2,500 genera. A fiche edition has been published.
