Dissolved oxygen plays a key role in microalgal growth at high density. This effect was so far rarely quantified. Here we propose new model to represent the combined of light, concentration and temperature (LOT-model) on microalgae growth. The LOT-model introduces order oxidative stress affecting cultures, adding toxicity term expression net rate. validated with experimental data for several sp...

This short communication reports a pioneering research of using bacteria for simultaneous algal cell disruption and cell wall/membrane utilization. Microalgae are regarded as one of the most promising feedstock that can potentially address the twin challenges of energy security and environmental protection due to their fast growth rate, high lipid content and CO2 biofixation capabilities. Howev...

Article history: Received on: 21/05/2016 Revised on: 23/06/2016 Accepted on: 14/07/2016 Available online: 30/08/2016 In the present study, the effects of hypo-osmotic and hyper-osmotic shock on β-carotene and glycerol production by a native strain of Dunaliella salina isolated from Maharlu Salt Lake, Fars province, Iran, were investigated. The amount of β-carotene and glycerol at 1 h, 2 h, 8 h ...

PURPOSE Ultraviolet B (UVB) radiation from sunlight is known to be a risk factor for human corneal damage. The purpose of this study was to investigate the protective effects of Dunaliella salina (D. salina) on UVB radiation-induced corneal oxidative damage in male imprinting control region (ICR) mice. METHODS Corneal oxidative damage was induced by exposure to UVB radiation at 560 μW/cm(2). ...

The locally isolated harpacticoid copepods Tigriopus sp. and Tisbe holothuriae were subjected to salinity tolerance experimentation at salinities under above of 40 ppt, presented high halotolerances in LC50 (24 h) 1 ± 4.43 ppt 132 5.35 respectively, 15 2.41 93 3.23 respectively. Tetraselmis suecica, among other microalgal feeds (Asteromonas gracilis, Rhodomonas salina, Dunaliella salina Isochry...

Heat shock protein 90 (Hsp90) is a molecular chaperone highly conserved across the species from prokaryotes to eukaryotes. Hsp90 is essential for cell viability under all growth conditions and is proposed to act as a hub of the signaling network and protein homeostasis of the eukaryotic cells. By interacting with various client proteins, Hsp90 is involved in diverse physiological processes such...

The effect of sulfur limitation on the partitioning of carbon, nitrogen, and sulfur was investigated in Dunaliella salina. D. salina was able to adapt to 6 microM sulfate; under these conditions, the cells showed reduced growth and photosynthetic rates. Whereas intracellular sulfate was depleted, phosphate, nitrate, and ammonium increased. Amino acids showed a general increase, and alanine beca...
