Dunaliella salina and D. bardawil are well-known microalgae accumulating high levels of beta-carotene under growth-limiting conditions. In both taxa, this pigment is primarily composed of the isomers 9-cis and all-trans. The 9-cis beta-carotene occurs only in natural sources and is the most attractive from a commercial point of view. The conditions that enhance the preferred accumulation of 9-c...

The American brine shrimp Artemia franciscana is invasive in the Mediterranean region where it has displaced native species (the sexual A. salina, and the clonal A. parthenogenetica) from many salt pond complexes. Artemia populations are parasitized by numerous avian cestodes whose effects have been studied in native species. We present a study from the Ebro Delta salterns (NE Spain), in a salt...

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). ...

Dunaliella salina (D. salina) is a potential source of lipids and subsequent biodiesel production. However lipid production from dependent on biomass production rate and lipid content. To get more lipid, production efficiency need to be improved. The aim was to application of two-stage culture strategy for improved microalgal growth and lipid Production. In this study the culture was grown unde...

The variation of the lipophilic (carotenoids and α-tocopherol) and hydrophilic (glutathione and ascorbic acid) antioxidant contents, and the activities of antioxidant enzyme such superoxide dismutase (SOD), catalase (CAT) and peroxidase (POD), as well as cellular malonaldehyde and stable radicals of D. salina in response to ultraviolet B (UV-B radiation 290-320 nm) and secondary carotenoid indu...

background: much of the environment is affected by petroleum contamination. it imposes serious health problems for humans as well as serious environmental impact. bioremediation is an important consideration for removing environmental pollutants because, compared with other technologies, it incurrs lower costs and is environmentally compatible. methods: crude oil degrading bacteria were isolate...

the objective of this study was to isolate halophilic bacteria with the ability to produce intracellular or extracellular l-asparaginase. a total number of 120 halophilic bacteria were isolated from 17 different saline habitats of iran including salt lakes, wetlands, brine springs and deserts. among these, 68 were able to grow in the presence of 1.5 m nacl and 52 demonstrated the ability to gro...

The temporal stability and diversity of bacterial species composition as well as the antilisterial potential of two different, complex, and undefined microbial consortia from red-smear soft cheeses were investigated. Samples were collected twice, at 6-month intervals, from each of two food producers, and a total of 400 bacterial isolates were identified by Fourier-transform infrared spectroscop...

Article history: Received on: 11/04/2016 Revised on: 09/05/2016 Accepted on: 24/06/2016 Available online: 29/10/2016 Drug resistance in microorganisms is an emerging phenomenon that poses challenges to public health and treatment. The reservoir of drug resistance genes found in the resistome of environmental isolates in aquatic saline systems has been augmenting continuously. The spread of drug...
