The Permanent Mission of Italy to the United Nations Office and other international organizations in Geneva presents its compliments to the World Intellectual Property Organization and has the honor to transmit to it the request of the Collection of Industrial Yeasts, Plant Biology Institute of the University of Perugia (Faculty of Agriculture), to acquire the status of international depositary authority (IDA) under Articles 6 and 7 of the Budapest Treaty (April 28, 1977) on the International Recognition of the Deposit of Microorganisms for the Purposes of Patent Procedure.

The request, accompanied by the relevant documents, was forwarded to us by the Ministry of Industry - Patent and Trademark Office. That Ministry, which has carried out the verifications required by the applicable provisions, considers that the Collection concerned complies with and will continue to comply with the required functional criteria and the objective conditions of competence, that is to say impartiality and structural and professional capability laid down by the Budapest Treaty for the acquisition of the status of international depositary authority (IDA).

II. Activities of the Collection DBVPG

7(a) The activities of the Collection DBVPG may be summarized as follows:

(i) isolation, identification and cataloguing of cultures;

(ii) conservation, conventional and molecular classification for third parties;

(iii) conservation of strains by the following methods:

- in 10 x 160 mm glass tubes on malt gelose at 4°C
- lyophilization in glass ampoules at room temperature
- cryoconservation at -80°C;

7(f) None of the deposits made so far concern patents.

7(g) The Collection DBVPG currently publishes a paper catalogue in which most of the information on the conserved strains is given. A catalogue on a magnetic support drawn up as part of the MINE (Microbial Information Network Europe) activities supported by the Commission of the European Community, is also available in the German database DIMDI in Cologne. The complete catalogue is currently being transferred to the Internet, with a page devoted to DBVPG. The on-line interrogation service will be available next year.

III. Procedures for the Deposit of Microorganisms

A. Acceptance of Cultures for Deposit

8. The Collection DBVPG requires, for acceptance as a deposit, compliance with the following conditions:

(i) Samples must be sent in test tubes in liquid or gel form or in freeze-dried ampoules in rigid-sided containers. In the event of consignment in a frozen or deep frozen form, containers of expanded polystyrene must be used containing a quantity of dry ice sufficient to guarantee 48 hours autonomy at room temperature.

(ii) The cells of the strains dispatched must be in pure culture and provide a high level of viability.

9(a) The depositor must supply:

A written declaration signed by the depositor and containing:

- a statement that the deposit has been made under the Budapest Treaty and an undertaking that it will not be withdrawn during the period provided in Rule 9.1 of the Regulations;

- the name and address of the depositor;

- a detailed description of the conditions that must be complied with for growing the deposited yeast culture, for conserving it and for verifying its viability;

- the dual appellation (genus and species), if it already exists and any identification code (number, symbol, acronym) allocated by the depositor;

- a statement of the properties of the strain that involve or may involve hazards for health or the environment or a statement that the depositor is not aware of any such properties. The depositor undertakes to inform the Collection DBVPG without delay should he acquire new information on the properties of the deposited strain that modify the statements previously made.

9(b) A scientific description and the origin of the strain deposited.

9(c) The form drawn up by the Collection DBVPG containing the information the depositor must provide when making his deposit.

B. Conservation

10(a) Methods of conservation and quality control for the deposited strains to guarantee viability and absence of contamination:

10(b) Contamination by bacteria, fungi or acarina can be identified by microscope inspection. In the presence of acarina, the dispatched culture is immediately sterilized.

10(c) The viability of strains is automatically tested since each culture received at DBVPG is immediately isolated on a gel medium to check whether a culture is dual or mixed. In the presence of colonies of differing macroscopic appearance and differing cell form, the depositor is informed.

10(d) The correctness of the taxonomic designation supplied by the depositor is checked at DBVPG by re-identification with conventional methods and by molecular taxonomy. In the cases of diverging identification, the depositor is informed of the difference.

10(e) Method of conservation on malt gelose: the strains are transferred on a fresh medium with an average frequency of two years and conserved under sterile mineral oil at 4°C.

10(f) Method of conservation in freeze-dried form: the cell powder is conserved at room temperature in at least 12 different ampoules for each strain. Viability checks are carried out every three to four years.

10(g) Method of conservation in deep-frozen form: a 24-hour cell suspension on malt gelose is deep-frozen at -80°C in the presence of 20 small pierced sterile beads. The container with the beads is conserved at -80°C and the culture may be recovered from a bead which is easily retrieved.

10(h) The Collection DBVPG cultivates strains according to three different methods: the three conservation lines are kept physically separate in different premises at a distance from the laboratory in order to minimize the danger of loss by fire or other hazard. Periodical controls of the -80°C alarm systems of the refrigerator and careful checks of the sterility of the culture media and viability of the conserved strains are foreseen.

C. Fees

11(a) The amount of the fee due on deposit under the Budapest Treaty (Rule 11.(4)(g)) is 1,000,000 lire for storage of a yeast strain.

Issue of a viability statement 100,000 lire
Cost of despatch for the furnishing of a sample 150,000 lire
Any notification to competent authorities or authorized persons concerning scientific data or the taxonomic description under Rules 6.1(b), 6.2(a)(iii), 7.6 and 8.1(b)(iii) 40,000 lire

11(b) The amount of the fees does not depend on the nationality or the domicile of the depositor, nor on the authority or the natural or legal person requesting issue of a viability statement or the furnishing of a sample.
