The microalgal strain Chlorella sorokiniana isolated from a waste stabilization pond was used for tertiary treatment of municipal wastewater. Three light:dark (L:D) regimes 12:12, 16:8, and 24:0 were treating wastewater in microalga (A), + sludge (A S), (S) reactors. removal nutrients (N P) found to be the highest microalga-based reactor, with more than 80% biochemical oxygen demand (BOD) 1.2–5...

Glycosylation of bisphenol A, which is an endocrine disrupting chemical, was investigated using immobilized marine microalga and plant cells from the viewpoint of bioremediation of bisphenol A. Immobilized marine microalga of Amphidinium crassum glucosylated bisphenol A to the corresponding glucoside. On the other hand, bisphenol A was glycosylated to its glucoside, diglycoside, gentiobioside, ...

In the summer of 2003, a microalga strain was isolated from a massive green microalgae bloom in wastewater stabilization ponds at the treatment facility of La Paz, B.C.S., Mexico. Prevailing environmental conditions were air temperatures over 40 degrees C, water temperature of 37 degrees C, and insolation of up to 2400 micromol m2 s(-1) at midday for several hours at the water surface for four ...

When the diatom, Phaeodactylum tricornutum, and the microalga, Dunaliella tertiolecta, are cultured together in a chemostat at dilution factors of approximately 0.5 day-1, the diatom develops the higher population density. At dilution factors above 1.2 day-1 the inability of the diatom to assimilate nutrient as fast as it flows into the chemostat results in the microalga generating the larger p...

Microalga-based fuels are promising solutions for replacing fossil fuels. This feedstock presents several advantages such as fast growth in a harsh environment and an ability to trap gases emitted from industries, thus reducing global warming effects. An efficient way convert harvested microalgae into biofuels is hydrothermal liquefaction (HTL), which yields intermediate product called biocrude...

Extraction of compounds from microalgae requires cell disruption as a pretreatment to increase extraction yield. Botryococcus braunii is a microalga with a significant content of carotenoids and other antioxidant compounds, such as chlorophylls. Cell disruption of B. braunii using CO2 rapid depressurization was studied as a pretreatment for the extraction of carotenoid and chlorophyll pigments....

Growth responses and total lipid content of a native strain of the biofuel potential freshwater oleaginous microalgae A.falcatus was studied owing to its inherently high lipid content for potential utilization as renewable biomass feedstock of biofuels. Influences of salinity in increasing order from 40 mM to 320 mM of NaCl in BG11 medium on growth (μ), total lipid (TL) content and calorific va...

there are many freshwater snails involved in the life cycle of parasitic flukes. some of these animals, such as bulinus spp and lymnaea spp are very important in public health and veterinary medicine. for example, bulinus trucatus and lymnaeid snails transmit human bilharziosis and zoonotic fascioliosis, respectively. for this reason most freshwater bodies of northern iran, were searched for po...
