Chronic combined nitrogen deficiencies characterize vast                        segments of the world's oceans. Microbial nitrogen fixation                     helps to alleviate these deficiencies.  The role of eubacteria                  as nitrogen fixers has received less attention than                             cyanobacteria.  This project focuses on the role of eubacteria                  in N-depleted North Carolina coastal waters using recently                      developed immunological and molecular techniques to provide a                   cell specific set of fluorescence and isotopic assays of                        bacterial population and community dynamics in benthic and                      planktonic habitats.  Such techniques and assays allow for                      identification of cells competent and induced to fix N, and                     provide a means to detect the presence of nitrogenase genes in                  total population DNA.  These techniques will allow (1) direct,                  quantitative information on microbial N fixation potentials and                 sites thereof, (2) assessment of environmental conditions that                  regulate nitrogenase gene expression, and (3) evaluation of                     recently described, numerically and trophically important                       picoplanktonic cyanobacteria for their N fixing capabilities.
