This work examines the effects of six pesticides on five green algae: Pseudokirchneriella subcapitata, Scenedesmus quadricauda, Scenedesmus obliquus, Chlorella vulgaris and Chlorella pyrenoidosa. The results indicate that the decreasing order of the average toxicity to five algae was: fluazinam > propineb > maneb > mancozeb > zineb > bromoxynil octanoate. however, according to sensitivity magni...
in the present study, the effects of chlorella vulgaris on blood and immunological parameters of caspian salmon (salmo trutta caspius) before and after exposure to viral nervous necrosis (vnn) virus were examined. in this regard, four treatments in triplicate were chosen. groups included one control and 3treatments (t1, t2 and t3). fish in control group, t1, t2 and t3 were fed diets supplement...
background and objective: chlorella vulgaris is a multi-cellular edible algal species with abundant proteins. extraction of high value protein fractions for pharmaceutical and nutritional applications can significantly increase the commercial value of microalga biomasses. there is no known report on the anticancer peptides derived from the chlorella vulgaris abundant protein. materials and meth...
Growth of Chlorella sorokiniana is unaffected by the choice of atmospheric diluent gas. Reduced total pressure has no inhibitory effect and may be slightly stimulatory.
The removal and biodegradation of nonylphenol (NP) by four freshwater microalgae, including three green algae (Scendesmus quadriauda, Chlorella vulgaris, and Ankistrodesmus acicularis) and one cyanobacterium (Chroococcus minutus) were studied in bacteria-free cultures exposed to different concentrations of NP for 5 days. All four algal species showed a rapid and high ability to remove NP (inclu...
The aim of the present study was to investigate selenite effects in the unicellular green algae Chlorella vulgaris as a primary producer and the relationship with intracellular bioaccumulation. The effects of selenite were evaluated by measuring the effect of different selenite concentrations on algal growth during a 144 h exposure period. It was found that lower Se concentrations (≤ 75 mg L(-1...
Global warming and ozone depletion, and the resulting increase of ultraviolet radiation (UVR), have far-reaching impacts on biota, especially affecting the algae that form the basis of the food webs in aquatic ecosystems. The aim of the present study was to investigate the interactive effects of temperature and UVR by comparing the photosynthetic responses of similar taxa of Chlorella from Anta...
The effect of the bacterium Azospirillum brasilense jointly immobilized with Chlorella vulgaris or C. sorokiniana in alginate beads on total carbohydrates and starch was studied under dark and heterotrophic conditions for 144 h in synthetic growth medium supplemented with either d-glucose or Na-acetate as carbon sources. In all treatments, enhanced total carbohydrates and starch content per cul...
The bioaccumulation of estrone by Daphnia magna was determined. Direct uptake via the aqueous medium occurred within the first 16 h. A bioconcentration factor of 228 was established over all temporal periods. Ingestion via Chlorella vulgaris gave a partitioning factor of 24, which may approximate to a biomagnification factor assuming steady state conditions. These preliminary results indicate t...
Background and Objective: Non-alcoholic fatty liver disease has been identified as a major health -related problem.There is no proven therapy for NAFLD. However, a number of possible treatments have been proposed and studied. The aim of this study was to evaluate the therapeutic effects of both Chlorella Vulgaris and Artichoke leaf extracts on NAFLD. Materials and Methods: In this clinical t...
