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

Molecular Chaperon DnaK from A Halotolerant Cyanobacterium Aphanothece halopytica
1998The DnaK/Hsp70 family is a molecular chaperone that has been extensively studied for its ability to assist the refolding and reassembly of a large number of diverse proteins. These protein support in the protection and recovery of cells from the ill effects of stress.

Nitrogen fixation by the unicellular blue-green alga Aphanothece
Archiv f�r Mikrobiologie, 1973Frequent 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, 1993The 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, 2019Cell 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, 1976About 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.

Nitrate uptake by halotolerant cyanobacterium Aphanothece halophytica
Nitrate uptake has been studied in the halotolerant cyanobacterium Aphanothece halophytica by monitoring nitrate remaining in the solution after contacting with the cells. Study of kinetics of nitrate uptake by cells grown under normal (0.5 M NaCl) and salt stress (2 M NaCl) conditions revealed Ks values of 416 and 450 micro-M respectively, the maximumopenaire +1 more source
