Isolation and characterization of a dnaK genomic locus in a halotolerant cyanobacterium Aphanothece halophytica

Plant Molecular Biology, 1997
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, 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.

Crystallization and a 5 Å X-ray Diffraction Study of Aphanothece sacrum Ferredoxin

The Journal of Biochemistry, 1978
A 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 ...

การเปลี่ยนแปลงด้านเมตาบอลิสมในสาหร่ายสีเขียวแกมน้ำเงิน สายพันธุ์ Aphanothece halophytica ที่เจริญภายใต้ความเครียดของเกลือ : รายงานผลการวิจัย

1989
ได้ทำการศึกษาอิทธิพลของเกลือโซเดียมคลอไรด์ในอาหารเลี้ยงเชื้อ ที่มีต่อการเปลี่ยนแปลงทางด้านเมตาบอลิสมของสาหร่ายสีเขียวแกมน้ำเงินสายพันธุ์ Aphanothece halophytica พบว่าที่ระยะ Late log phase เมื่อเพิ่มความเข้มข้นของเกลือโซเดียมคลอไรด์จากสภาวะปกติ 0.5 M เป็น 1 M และ 2 M เซลล์มีความสามารถในการตรึงคาร์บอนไดออกไซด์เพิ่มขึ้นตามลำดับ ในขณะเดียวกันเอนไซม์ที่สำคั

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.

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.

Characteristics of thin-layer drying of the cyanobacterium Aphanothece microscopica Nägeli

Chemical Engineering and Processing: Process Intensification, 2007
Abstract 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.

Rates of CO2 removal by Aphanothece microscopica Nägeli in tubular photobioreactors

Chemical Engineering and Processing: Process Intensification, 2008
Abstract The integral method for the analysis of kinetic data was used to describe the removal of carbon dioxide dissolved in the aqueous phase of a tubular photobioreactor by Aphanothece microscopica Nageli. The effects of the carbon dioxide concentration (3, 15, 25, 50 and 62%), light intensity (960, 3000, 6000, 9000 and 11,000 lux) and temperature

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.

Interaction of constituent subunits in ribulose 1,5-bisphosphate carboxylase from Aphanothece halophytica

Archives of Biochemistry and Biophysics, 1984
Ribulose 1,5-bisphosphate carboxylase-oxygenase (RuBisCO) from the halophilic cyanobacterium, Aphanothece halophytica, dissociates into catalytic core (large subunit A oligomer) and small subunit B under low ionic strength during sucrose density gradient centrifugation.
