امروزه، جهت پالایش آلاینده های مختلف ورودی به محیط زیست به خصوص فلزات سنگین از روشهای زیستی استفاده می شود. جلبک ها از جمله موجوداتی هستند که قادرند با مکانیسم های مختلف اقدام به تجمیع و تبدیل این آلاینده ها نمایند. در این راستا از تکنیک تثبیت این میکروارگانیسم ها در جهت اهداف مختلف بهره برداری می گردد. لذا پس از غربالگری اولیه ریزجلبک های spirulina، tetraselmis، chlorella، scenedesmus، microch...

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...

The effect of different photoperiods: 24 h illumination and a 12:12-h light/dark (12L:12D) cycle on the growth rate and biomass productivity was studied in five algal species: Neochloris conjuncta, Neochloris terrestris, Neochloris texensis, Botryococcus braunii and Scenedesmus obliquus. The green microalgae examined differ in the reproduction mode. Continuous illumination stimulated the growth...

Microalgae are well known for their biotechnological potential, namely with regard to bioactive lipidic components-especially carotenoids and polyunsaturated fatty acids (PUFA), well-known for therapeutic applications based on their antioxidant capacity. The aim of this work was to evaluate the influence of four distinct food-grade solvents upon extractability of specific lipidic components, an...

Open raceway ponds are cost-efficient for mass cultivation of microalgae compared with photobioreactors. Although low-cost options like wastewater as nutrient source is studied to overcome the commercialization threshold for biodiesel production from microalgae, a cost analysis on the use of wastewater and other incremental increases in productivity has not been elucidated. We determined the ef...

In this work, the capacity of wastewater from an inland fishery system in Colombia (Norte de Santander) was tested as culture medium for Chlorella sp. and Scenedesmus Due to insufficient N P concentrations successful algae growth, effect replenishment with NO3, PO4, Na2CO3 or NaHCO3 a carbon source analyzed using three-factor nonfactorial response surface design. The results showed that additio...

Microalgae biomass can produce high quantities of biochemicals that be used in various applications such as biodiesel, biogas, and aquaculture feed. The potential sterilizing wastewater for microalgae-based treatment on a lab scale is well introduced. However, the operation cost large-scale microalgae cultivation plants if using sterilising growth medium. present study aimed to evaluate Scenede...

The green alga Scenedesmus was investigated for its ability to remove nitrogen from anaerobic digestion effluent possessing high ammonium content and alkalinity in addition to its growth characteristics. Nitrate and ammonium were indistinguishable as a nitrogen source when the ammonium concentration was at normal cultivation levels. Ammonium up to 100ppm NH(4)-N did not inhibit cell growth, but...
