This work shows the results of biosynthesis silver nanoparticles using microalga Chlorella sp, growth media with different concentrations glycerol, between 5%–20%, and light temperature conditions. The synthesis was studied supernatants pellets from autotrophic, heterotrophic mixotrophic cultures microalga. presence verified by ultraviolet-visible spectroscopy samples showing highest concentrat...

In this work, photostability, absorption and emission intensity of coated polycarbonate (PC) sheets with optical brightener (OB) as a wavelength converter material have been investigated. In addition, this coated sheet was used as a wall for microalgae culture flask, as a small scale photobioreactor, for studying the spectral conversion of UV-A radiation to blue light region and its effect ...

Freshwater deficiency and growing requests for renewable energy have led to increased concern about water security. Therefore, the present study attempted evaluate feasibility of using wastewater (WW) as a culture medium microalgal cultivation with aim nutrient removal biodiesel production. The green microalga Asterarcys quadricellulare (Chlorophyta) was isolated from treatment plant in Menoufi...

Pollution of aquatic bodies by pharmaceutical compounds is an emerging environmental problem because these drugs are extensively used in animal and human medicine. Ibuprofen, 2-[4-(2-methylpropyl)phenyl] propanoic acid, the non-steroidal anti-inflammatory drug mainly present both wastewater rivers lakes Europe. Despite this emergency giving rise a great interest scientific community, literature...

Abstract Marine microalgae often live in a fluctuating environment including decrease salinity caused by global warming induced sea ice melting and freshwater inflows. Under conditions of salinity, have evolved variety survival mechanisms such as lipid accumulation remodeling. The purpose this study was to investigated the membrane remodeling marine green microalga Dunaliella tertiolecta short-...

background: the purpose of this study was to perform seroepidemiological investigation for determining the status of human fasciolosis in pirabad village, lorestan province, western iran. methods: blood samples were taken from residents of the village including 801 individuals. sera were separated and stored at -20°c until used. the samples were analyzed using elisa. results: anti- fasciola ant...

Harvesting of algal biomass in biodiesel production involves high energy input and cost incurred process. In order to overcome these problems, bioflocculation process was employed and the efficiency of this process was further improved by the addition of a cationic inducer. In this work marine Bacillus subtilis was used for bioflocculation of Nannochloropsis oculata and ZnCl2 as cationic induce...

Cadmium tolerance and removal in the marine microalga Dunaliella salina were studied in cultures exposed to different metal concentrations (5-120 mg Cd l(-1)) for 96h. This microalga can be included in the group of microalgal species most tolerant to cadmium due to the high value of EC50 that it possesses (48.9 mg Cd l(-1) at 96 h of culture). The greater percentage of cadmium removed was obtai...

Microalgae that are of interest for biofuel production must be able to tolerate environmental changes occur in outdoor cultivation systems. While algal cultures may experience daily temperature fluctuations and seasonal changes, the underlying mechanisms control regulate physiological responses adaptation pressures largely unknown. Systems-level characterization enabled by functional genomics c...
