title: [Energy supply for nitrogen fixation of Anabaena sp. CH1 and CH2].
abstract: Energy needed for nitrogen fixation in Anabaena sp. has been studied. It was found that energy produced from photosynthesis but not from respiration was the main source for nitrogen fixation of Anabaena sp. CH1. In strain CH2, both photosynthesis and respiration supplied energy for nitrogen fixation. Some respiratory enzyme activities (IDH, MDH) were also higher in vegetative cells of strain CH2 than of strain CH1.
