Nitrogen Fixation by symbiotic organisms is considered an
important contribution to the solution of food problems
throughout the world. For manyyears, Chinese scientists
have focused their research in this area. Today more than
half of the total nitrogen fertilizers applied are from
biological fixation sources.
The editor is an international renowned scientist at the
Chinese Academy of sciences. He has brought together
contributions from various research fields in China and
Europe.Together they present the state-of-the-art in
nitrogen-fixation research. The studies range from actino-
mycete fixation induced in various genera andspecies of
plants, mechanisms and chemical modeling of enzyme systems
togenetical engineering of organisms.
