Na+/H+ exchange activity in whole cells of the halotolerant alga DunaIfeila saUna can be elicited by intracellular acidification due to addition of weak acids at appropriate external pH. The changes in both intracellular pH and Nat were followed. Following a mild intracellular acidification, intracellular Nat content increased dramatically and then decreased. We interpret the phase of Nat influ...

Provision of copepod nauplii as food increases larval survival in many fish species that are difficult to rear using standard practices. Gladioferens imparipes is a temperate estuarine calanoid copepod with culture potential. Diets were tested to determine which would maximise copepod production. Copepods were fed five diets: Isochrysis galbana, Chaetoceros muelleri, Dunaliella tertiolecta, Nan...

the microalgae, dunaliella salina was isolated from maharlu salt lake, south east of shiraz, iran. the isolated strain was identified by both morphological and physiological markers. the complete its region (its1 + its2) including the 5.8s rdna gene used as molecular marker confirmed our identification. growth and cell proliferation, total chlorophyll and carotenoid contents were determined in ...

Bloom of Dunaliella salina was observed naturally in stagnant puddles of water off Kuwait's Bubiyan Island on 4 July 2004. In order to closely monitor this bloom, alga were collected and maintained as pure culture of the locally isolated D. salina. Set of experiments was conducted to study and evaluate the optimum culture conditions required for two samples of D. salina (one locally isolated an...

The mechanism of abiotic stress tolerance is crucial for plants to survive in harsh condition and the knowledge of this mechanism can be use to solve the problem of declining productivity of plants or crops around the world. However in-depth description is still unclear and it is argued, in particular that there is a relationship between high salinity tolerance and the ability to tolerate high ...

In addition to biochemical, physiological and morphological analysis, molecular studies provide additional information for establishing phylogenetic relationships among different species and strains of the genus Dunaliella. In the present study, based on neighbor- joining analysis of the nuclear rDNA ITS sequence, a novel strain of the green algae Dunaliella viridis was identified from Maharlu ...
