Ribulose 1,5-bisphosphate carboxylase from the halophilic cyanobacterium Aphanothece halophytica

Archives of Biochemistry and Biophysics, 1983
Various structural and functional properties of ribulose 1,5-bisphosphate carboxylase/oxygenase (RuBisCO) isolated from the halophilic cyanobacterium (blue-green alga) Aphanothece halophytica were reexamined. The ready dissociation of this algal RuBisCO during sedimentation in a linear sucrose density gradient was observed.

Nitrogen fixation by the unicellular blue-green alga Aphanothece

Archiv f�r Mikrobiologie, 1973
Frequent growth of unicellular blue-green alga Aphanothece sp. was observed in medium free of combined nitrogen. Its generation time was 12 h and more than 2 mg of nitrogen was fixed in 25 days. Its growth and nitrogen fixation were comparable to other heterocystous algae.

Plasma membrane lipid composition of the halophilic cyanobacterium Aphanothece halophytica

Archives of Microbiology, 1993
The plasma membrane from Aphanothece halophytica was isolated using both glycerol and sucrose gradient centrifugation. The isolated membrane was characterized for lipid content by TLC and isolated lipids were quantified by chemical analysis. The plasma membrane of A. halophytica was composed of MGDG, DGDG and PG.

Enhanced dark fermentative H2 production by agar-immobilized cyanobacterium Aphanothece halophytica

Journal of Applied Phycology, 2019
Cell immobilization is one of the techniques used to improve H2 productivity in cyanobacteria. In this study, H2 production by immobilized cells of unicellular halotolerant cyanobacterium Aphanothece halophytica was investigated and optimized. The results showed that immobilized cells of A.

A minor component of ferredoxin from Aphanothece sacrum cells.

Journal of biochemistry, 1976
About 20% of the total extractable ferredoxin from a blue-green alga, Aphanothece sacrum, was separated as a minor component on a DEAE-cellulose column during the preparation of the major component of the cells. It was always found in cells collected in three different seasons.
