We cloned and characterized a genomic locus encoding a distinct member of the DnaK/Hsp70 family of molecular chaperones, dnaK1, from the halotolerant cyanobacterium Aphanothece halophytica. Co-expression of dnaK1 with a plant plastocyanin precursor in Escherichia coli resulted in a dramatic increase in the solubility of the plant protein.

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.

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.

Crystallization and a 5 Å X-ray Diffraction Study of Aphanothece sacrum Ferredoxin
The Journal of Biochemistry, 1978A chloroplast-type ferredoxin containing two non-heme iron and two labile sulfur atoms per molecule was prepared from Aphanothece sacrum. Crystals were obtained by dialysis against 75% saturated a-monium sulfate solution, and belong to the tetragonal system with cell dimensions a = b = 92.2 A and c = 47.6 A, containing four molecules in an asymmetric ...

Characteristics of thin-layer drying of the cyanobacterium Aphanothece microscopica Nägeli
Chemical Engineering and Processing: Process Intensification, 2007Abstract This study was undertaken to investigate the dehydration characteristics of the cyanobacterium Aphanothece microscopica Nageli in a convective hot-air dryer. The dehydration characteristics of the biomass were examined at air temperatures of 40, 50 and 60 °C and sample thicknesses of 3, 5 and 7 mm.

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.

Regulation of Glycinebetaine Accumulation in the Halotolerant Cyanobacterium Aphanothece halophytica
Australian Journal of Plant Physiology, 1993When cells of the halotolerant cyanobacterium, Aphanothece halophytica were transferred from control culture medium that contained 0.5 M NaCl to a hypersaline medium with either 1.5 M or 2.0 M NaCl, the rate of photosynthetic CO2 fixation fell instantaneously. Subsequently, the photosynthetic activity returned to almost the original level within 1 day.
