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.

Aphanothece microscopica Nageli 1849

2014
Aphanothece cf. microscopica Nägeli (1849: 59) (Figs. 1H–1I). Round colonies, 24.6–77.8 µm diam., sub-colonies often present, 8.0–12.7 µm diam. Sheath firm, hyaline, conspicuous. Cells sparsely to densely disposed, cylindrical, rarely ellipsoid, 3.1–6.0(7.2) × 1.7–2.9 µm, 1.8–2.0 times longer than wide. Cell content slightly granulated, intense blue-

Ion metabolism in a halophilic blue-green alga, Aphanothece halophytica

Archives of Microbiology, 1976
The intracellular ion content of the halophilic blue-green alga, Aphanthece halophytica was studied as a function of age, external sodium and external potassium concentration. Intracellular Na+ was found to be about 0.38 millimoles/g dry mass. Intracellular K+ concentrations were as high as 1 M and varied directly with external salinity.

CELL WALL CONSTITUENTS OF APHANOTHECE HALOPHYTICA (CYANOPHYTA)¹

Journal of Phycology, 1979
ABSTRACTSome aspects of the cell wall and extracellular polysaccharide (ECPS) of the obligate halophile Aphanothece halophytica Frémy (Chroococcales) have been investigated. Extracellular polysaccharide concentration was found to remain constant on a per cell basis in medium containing from 1–3 M NaCl.

Purification and Kinetic Properties of Betaine-Homocysteine Methyltransferase from Aphanothece halophytica

Current Microbiology, 2001
Betaine-homocysteine methyl transferase (BHMT) from Aphanothece halophytica was purified to homogeneity by hydroxyapatite, DEAE-Sepharose CL-6B and Sephadex G-200 column chromatography. A 24-fold purification and 11% overall yield were achieved with a specific activity of 595 nmol h(-1) mg(-1).

Zinc Biosorption from Aqueous Solution by a Halotolerant Cyanobacterium Aphanothece halophytica

Current Microbiology, 2002
We have investigated the characteristics of zinc biosorption by Aphanothece halophytica. Zinc could be rapidly taken up from aqueous solution by the cells with an equilibrium being reached within 15 min of incubation with 100 mg L(-1) ZnCl(2). The adsorbed zinc was desorbed by treatment with 10 mM EDTA.

Factors affecting biohydrogen production by unicellular halotolerant cyanobacterium Aphanothece halophytica

Journal of Applied Phycology, 2012
The effects of several physiological parameters on H2 production rate in the unicellular halotolerant cyanobacterium Aphanothece halophytica were investigated. Under nitrogen deprivation, the growth of cells was inhibited, but H2 production rate was enhanced approximately fourfold.
