This study was performed to compare the efficiency of six microalgae namely Dunaliella tertiolecta, Tetraselmis suecica, Nannochloropsis oculata, Chaetoceros sp., Chlorella sp. and Spirolina sp. on the growth, survival rate and reproduction efficacy in Artemia urmiana in laboratory conditions. Artemia cysts were harvested from Urmia Lake and hatched according to the standard method. Live microa...
Growth of and the capacity to take up nitrogen in the freshwater microalgae Chlorella vulgaris were studied while varying the concentrations of ammonium and nitrate, the pH and the source of carbon in a synthetic wastewater growth medium when co-immobilized in alginate beads with the microalgae growth-promoting bacterium Azospirillum brasilense. Analyses of 29 independent experiments showed tha...
biodegradation of different concentration of dye (congo red dye) by using green and blue green algae
releasing of textile dye effluents into general water bodies is a major environmental and healthproblem. color removal, in particular, has recently become of major scientific interest, as indicated by themultitude of related research reports. during the past two decades, several physico-chemical decolorizationtechniques have been reported, few, however, have been accepted by the textile industr...
BACKGROUND The lipid content of microalgae is regarded as an important indicator for biodiesel. Many attempts have been made to increase the lipid content of microalgae through biochemical and genetic engineering. Significant lipid accumulation in microalgae has been achieved using biochemical engineering, such as nitrogen starvation, but the cell growth was severely limited. However, enrichmen...
The current paper presents data on the features of biotechnological cultivation chlorella microalgae strain IFR C-111 different nutrient media. Evaluation influence illumination period rate biomass growth selected medium has also been presented. There are materials suspension effect biological resource’s potential quails.
The freshwater microalgae Chlorella sp. and Vulgaris were cultured in a laboratory-scale photobioreactor their growth kinetics total lipid production evaluated. These species grown modified Conway medium, with an 8:16 photoperiod mechanical air ventilation. evaluation time was twenty days, the cell density determined daily using Neubauer chamber by optical spectrophotometry at 685 nm. rate perc...
Many farms in Uzbekistan, Ukraine, Kazakhstan and other republics arrange the production cultivation of chlorella microalgae special installations use suspensions as a protein-vitamin additive ration farm animals. The fattening cattle, pigs poultry allows for additional weight gain, elimination avitaminosis diseases improvement product quality.
In this study, it was possible to evaluate the production of polyhydroxyalkanoates (PHAs) from microalgae Chlorella vulgaris and Tetradesmus obliquus, using 1% 0.25% (v/v) agro-indusytial Corn Steep Liquor residue, a product corn processing. The biomass subjected mechanical extraction 4% sodium hypochlorite + chloroform, extract further characterized Fourier Transform Infrared Spectroscopy (FTI...
