Abstract
sp. strain PCC 7120. Our results show a close relationship between C and N fixation and distribution in the filaments and indicate that wild-type filaments in a culture can exhibit a substantial variability of metabolic states. This illustrates how some novel properties can be appreciated by studying microbial cultures at the single-cell level.
