INTRODUCTION
The Culture Centre of Algae and Protozoa (CCAP) in
Great Britain derived from the collection started
by E. G. Pringsheim in Prague in 1928. Pringsheim's
collection was expanded and eventually taken over by
E. A. George for Cambridge University in 1947. In
April 1970, it formed the basis of CCAP, financed by
the Natural Environment Research Council (NERC). In
November 1975, the Centre became part of the Institute
of Terrestrial Ecology (ITE) - itself a component of
NERC.
CCAP maintains (by serial cultivation or by
cryopreservation) over 2000 strains of protists
(including parasitic protozoa which can be cultivated
in vitro), the smaller multicellular algae, some
bryophytes, one rotifer, and one aquatic angiosperm.
The collection does not include the larger seaweeds
or, in general, pathogenic parasites.
CCAP supplies cultures for research and teaching,
advises on identification of related material and
undertakes fundamental taxonomic, morphological
and cryobiological research.
REQUESTS FOR CULTURES
Most cultures in this list are readily available:
some, which may be pathogenic to man, are indicated
in the list by '13' or 'P?and their availability is
restricted. All requests should be accompanied by an
official order when possible and should be addressed
to:-
Culture Centre of Algae and Protozoa,
36 Storey's Way,
CAMBRIDGE,
CB3 ODT,
ENGLAND.
Payment in POUNDS STERLING is due on receipt of the
cultures and invoice. Payment should not be sent in
advance unless requested.
Details of charges are given in the current price
sheet, available on request.
AT LEAST ONE MONTH'S NOTICE is requested, especially
for large orders and for cryopreserved material:
SUPPLY OF MATERIAL AT SHORTER NOTICE CANNOT BE
GUARANTEED. When cultures are required on a certain
date, this should be clearly indicated; otherwise they
will be sent as soon as they are ready.
Cultures are dispatched by First Class Mail or by
Registered Air Mail Letter Post as appropriate. A special
request must be made for cultures to be sent by Air
Freight.

IMPORTANT NOTE. Anyone using CCAP strains in work
which is subsequently published is earnestly requested
to give the full reference number of the strain,
eg CCAP 128/1. This will help to avoid subsequent
confusion in the identification of materials used.
EXPLANATORY NOTES
Genera, and species within them, are arranged
alphabetically in the body of the catalogue.
A systematic list of genera is given on page 4.1:
neither this list, nor the catalogue in general
should be taken as an authority for taxonomy or
nomenclature.
Strains are listed under the name of the species; the
information given below is included whenever possible:
(a) The reference number in the collection, which is
intended to be unique and immutable. Please
quote it in any published reference, including the
collection initials 'CCAP'.
(b) The name of the isolator and the year of isolation.
(c) Number given by isolator.
(d) Pathogenicity, whether the strain is a proven
pathogen to man (P) or possibly a pathogen to man,
but not proven (P?).
(e) Method of maintenance in the collection:
A = Agar slope (axenic when letter stands alone)
B = Bacteria present
L Liquid medium (axenic when letter stands
alone)
N Cryopreserved
X Organisms other than bacteria present
These code letters are combined as required; for
example:
AB
ABX
LBX
etc.
Agar + bacteria only
= Agar + bacteria + other organisms
= Liquid + bacteria + other organisms
IT SHOULD BE NOTED THAT THE ABOVE LETTERS DO NOT
FORM, PART OF THE STRAIN NUMBER. The strain
number is unchangeable and the letters merely
indiCate the method of maintenance and can be
altered as the method is altered. In earlier editions
of this catalogue, the method of maintenance was
indicated by a code letter preceding the strain
number. This practice has been discontinued, as
confusion arose from the frequent erroneous
inclusion of the code letter(s) in the strain
number.
