Photosynthetic nature of nitrate uptake and reduction in the cyanobacterium Anacystis nidulans
Abstract The photosynthetic nature of the initial stages of nitrate assimilation, namely, uptake and reduction of nitrate, has been investigated in cells of the cyanobacterium Anacystis nidulansExpand

Factors affecting the production of biomass by a nitrogen-fixing blue-green alga in outdoor culture
The effectiveness of an aeration-shaking (air-lift) system for outdoor biomass photoproduction by the N2-fixing filamentous blue-green alga Anabaena variabilis was evaluated and the influence ofExpand

Purification and properties of NADP-dependent non-phosphorylating glyceraldehyde-3-phosphate dehydrogenase from the green alga Chlamydomonas reinhardtii
Abstract NADP-dependent non-phosphorylating D -glyceraldehyde-3-phosphate dehydrogenase (EC 1.2.1.9), previously described in higher plants, has been now found to be present in eukaryotic greenExpand

Enhancement of phycobiliprotein production in nitrogen-fixing cyanobacteria
Summary The influence of several environmental factors on the phycobiliprotein content of two phycoerythrin-rich nitrogen-fixing cyanobacteria has been studied in order to maximize pigmentExpand

Regulatory interaction of photosynthetic nitrate utilization and carbon dioxide fixation in the cyanobacterium Anacystis nidulans
The rate of photosynthetic nitrate utilization in Anacystis nidulans is strongly influenced by the availability of carbon dioxide. This dependence can be relieved by inhibiting the metabolism of theExpand
