Algae are rich sources of amino acids, terpenoids, florentines, alkanes, halogenated ketones, steroidal compounds, fatty acids, and phenols that can be used in the pharmaceutical industry. The acetone and ethanol extracts, and the supernatant of the algae Chlorella vulgaris CCATM210-1, were used in this study. After culturing the Algae, and preparing the supernatant and extracts, the antibacter...

In synthetic wastewater, growth and phosphorus absorption by two species of microalgae, Chlorella sorokiniana and Chlorella vulgaris, and in domestic wastewater by C. sorokiniana significantly enhanced after a starvation period of 3 days in saline solution, combined with co-immobilization with the microalgae growth-promoting bacterium (MGPB) Azospirillum brasilense Cd in alginate beads. Starv i...

With the rapid development of nanotechnology and widespread use of nanoproducts, concerns have arisen regarding the ecotoxicity of these materials. In this paper, the photosynthetic toxicity and oxidative damage induced by nanoFe3O4 on a model organism, Chlorella vulgaris (C. vulgaris) in aquatic environment, were studied. The results showed that nano-Fe3O4 was toxic to C. vulgaris and affected...

N-Phenylethylamides 1a-1f, were isolated from cultures of three limnic strains GW90a, GW102a and GW73a. Strain GW102a delivered additionally the compound cyclo(isoleucyldehydroalanyl) (2). The structure of these compounds were assigned by a detailed spectral analysis. Due to their potential use as herbicides, various related compounds 1a, 3, 4a and 4b were synthesized. The minimum inhibitory co...

The effect of the microalgae-growth promoting bacterium Azospirillum brasilense on accumulation of total carbohydrates and starch in two species of Chlorella (Chlorella vulgaris and Chlorella sorokiniana), when the bacterium and each microalga were jointly immobilized in alginate beads was studied under autotrophic conditions for 144 h in synthetic medium. The interaction of the bacterium with ...

wastewater contains many organic and inorganic contaminants that can cause serious damage to the environment and health of people, therefore, they have to be eliminated before being downloaded into sensitive areas. different methods of wastewater purification have been used for contaminants removal. however, they present some technical and economic limitations. thus, new methods of nutrients re...

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...
