    1st International Conference on Nitrification

    July 5-10 2009

    University of Louisville, Kentucky, USA

    The first International Conference on Nitrification (ICoN1) brought together investigators and students at all levels to discuss the most recent concepts in nitrification research, including the ecology, physiology, biochemistry, molecular genetics, genomics, metagenomics, transcriptomics and evolution of ammonia- and nitrite-oxidizing bacteria and archaea, and their roles in the Nitrogen cycle. Participants from a wide range of disciplines from both academic, industrial and policy institutions from all over the world were present.

    Nitrification Network - Fostering Partnership

    2008 Travel Grants


The Nitrification Network - Fostering Partnership program provides limited funds to individuals wishing to visit a hosting laboratory to expand their research on nitrification.

    All researchers working in an area related to nitrification will be considered. Preference will be given to graduate students and post-doctors who might not have the facilities or the expertise to fully develop the potential of a project in their home laboratories. Individuals wishing to change or expand their research focus on nitrification may be also considered.

    Funding of up to $1500 will be provided to cover the cost of the airline ticket to visit the hosting laboratory. A maximum of ten awards per calendar year will be funded. 

    The application should be composed of:

      1. A one-page proposal from the applicant stating the rationale for the visit including a description of the project or collaboration to be established and its significance, the advantages that the applicant will find in the hosting laboratory (e.g. expertise, instrumentation, facilities, etc), and the anticipated enduring impact of the visit, dates of the visit, and a brief description of the research activities of the home and the host laboratories.

      2. A brief resume from the applicant.

      3. A statement from the principal investigator of the home laboratory indicating their support of the proposal.

      4. A statement from the principal investigator of the hosting laboratory indicating their support of the proposal.

All documents should be emailed to Luis Sayavedra-Soto (, preferably in portable document format (PDF) form. 

    All complete proposals will be evaluated by the Steering Committee of the Nitrification Network, who may request additional information. Applicants will be notified by email of the committee's decision within a month after receiving the proposal, or immediately if funds have been exhausted for 2008. 

At the end of the proposed activity, the awardees are required to submit a one-page summary of the results to Luis Sayavedra-Soto ( with permission to post the success of the award in the News and Events section of the Nitrification Network web site.

    Notes to the meeting held Februray 2007

    The Nitrification Network
    web site was made available to the public April 2007.

    The first Nitrification Network meeting took place in February 16-17 th, 2007 at Oregon State University. The investigators and their collaborators launched the project. Minutes to the meeting. The following Mission Satement and Charter were agreed upon:

    Mission Statement

      The mission of the Nitrification Network is to advance, facilitate and promote the study and understanding of nitrification.


      1. The inception of Nitrification Network was facilitated by a grant award made by the US National Science Foundation. Hence the Charter mandates that all federally funded activities of Nitrification Network will by guided by the rules of engagement that are advised and restricted by the policies of the US National Science Foundation.

      2. Charter members commit to interacting with openness towards collaboration. All members agree to honor confidentiality regarding the sharing of information, data, strains, clones, etc.

      3. While members agree that there is no right to reserve ideas and scientific projects for future work; collegiality, courtesy, and respect for the intellectual contributions of others shall be a general guide for all interactions of Nitrification Network members.

      4. Members of the Nitrification Network agree on the importance of fostering and mentoring students, post-doctoral associates and junior faculty for the successful continuation of present and future scientific pursuits and will provide opportunities for their professional growth and advancement. Such opportunities may include but not be restricted to joint attempts to obtain funding for research projects and training as well as joint publications.

      5. Participation in Nitrification Network will not exclude collaborations outside of the network; however, confidentiality of shared data and information within the network shall be honored.

      6. Nitrification Network is international in scope and invites the participation of colleagues from around the world.
