Ion metabolism in a halophilic blue-green alga, Aphanothece halophytica
Archives of Microbiology, 1976The 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, 1979ABSTRACTSome 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.

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, 2002We 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.

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.

Salt stress enhances choline uptake in the halotolerant cyanobacterium Aphanothece halophytica
Biochimica et Biophysica Acta (BBA) - General Subjects, 2003The uptake of [14C]choline by a suspension of exponential-phase Aphanothece halophytica under various conditions has been studied. Salt stress was found to enhance the uptake of choline. The kinetics of choline transport followed the Michaelis-Menten relationship with apparent K(m) values of 272 and 286 microM, maximum rates of transport (V(max)) of 18
