Abstract The effects of variation in major physico-chemical parameters on the growth of the Chroococcalean blue-green alga, Aphanothece halophytica in hypersaline media (2–4 m NaCl) were determined. Growth in media of varying salinity was influenced by interactions of light, temperature and CO2. Observed doubling times of 14·5, 18·0 and 30·0 h in 2, 3,

Two facultative anoxygenic photoautotrophic cyanobacteria, Oscillatoria limnetica and Aphanothece halophytica were found capable of CO2 photoassimilation using molecular hydrogen as electron donor in a photosystem I driven reaction. A. halophytica was also capable of evolving hydrogen from Na-dithionite reduced methylviologen in a light independent ...

The glycine-methylation biosynthetic pathway of glycinebetaine (GB) has been investigated, but only a few studies on GB accumulation in transgenic higher plants have utilized this pathway. In this study, two methyltransferase genes named ApGSMT2 and ApDMT2, encoding proteins catalyzing GB biosynthesis from glycine, were cloned from a relative strain of

PROTEIN AND AMINO ACID COMPOSITION OF THE OBLIGATE HALOPHILE APHANOTHECE HALOPHYTICA (CYANOPHYTA)1
Journal of Phycology, 1977ABSTRACTTotal protein was determined for cells of Aphanothece halophytica Fremy harvested during early log, mid‐log and linear growth phases in media containing 1, 2, and 3 M NaCl. Cells grown in medium containing 1 M NaCl showed a progressive increase in protein content up to a maximum of 76% of dry weight (linear phase).

Uptake of exogenous 14C-glycine betaine has been followed in the cyanobacterium Aphanothece halophytica and other species able to synthesise glycine betaine in response to osmotic stress. At 1 mmol dm−3 uptake was rapid (flux rate=29.50 nmol m−2 s−1), equilibrating at an internal concentration of 120 mmol dm−3 within 30 min.

Factors affecting the mutual interaction between the catalytic core [octamer of large subunit (A)] and the small subunit (B) comprising ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) from the superhalophilic cyanobacterium, Aphanothece halophytica, were investigated.

POLYSACCHARIDE RELEASE BY APHANOTHECE HALOPHYTICA INHIBITS CYANOBACTERIA/CLAY FLOCCULATION1
Journal of Phycology, 2010Many microalgae release polysaccharides, but the effects of the polysaccharides on mutual flocculation of microalgae and clay in aquatic environments have not been well studied. Aphanothece halophytica Frémy is a bloom‐forming cyanobacterium in salterns and can release large amounts of polysaccharide (AH‐RPS).

Biohydrogen is an environmentally friendly alternative energy carrier that can be produced by a number of different microorganisms. The unicellular halotolerant cyanobacterium Aphanothece halophytica is one of the high potential H2 producers. Under dark fermentation, it is capable of producing H2 by the bidirectional hydrogenase activity via the ...

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
