This European based biennial congress brings together scientists focused on biological N2 fixation (BNF) from diverse research topics of biochemistry, microbiology, computational genomics, plant physiology, and more recently genetic engineering and aquatic microbiology. The first ENFC was held in Szeged, Hungary, in 1994, with an emphasis on participation by young researchers. The most recent ENFC in 2016 was a clear demonstration of 'research without borders' as 294 participants, 30 % of which came from outside of the European Union (EU), including 8 % from developing countries, attended the 12th ENFC in Budapest, Hungary. A large percent (29%) of the participants were PhD students. The value of the ENFC series has been proven over the years. Price: Standard fee: EUR 465. Speakers: Ray Dixon, Christopher Voigt, Dennis Dean, John C. Meeks, Lance Seefeldt, Makoto Hayashi, Marie-Charlotte Nilsson Hegethorn, Martin Parniske, Myriam Charpentier. Time: 10:00 am to 5:00 pm.
