The aim of this study was to investigate if dietary Chlorella vulgaris (chlorella) intake would be effective on cadmium (Cd) detoxification in rats fed dietary Cd. Fourteen-week old male Sprague-Dawley (SD) rats weighing 415.0 +/- 1.6 g were randomly divided into two groups and fed slightly modified American Institute of Nutrition-93 Growing (AIN-93G) diet without (n=10) or with (n=40) dietary ...

Photosynthetic 0 2-evolution patterns were determined in cells of Chlorella vulgaris 211 — 11 h, grown under air enriched with 2% C 0 2 (High C 02-cells) and under ordinary air (Low C 0 2-cells). Oxygen evolution in these algae was measured as consequence of short saturating light flashes with the three electrode system according to Schmid and Thibault, Z. Naturforsch. 34c, 414 (1979). It was s...

The present study was undertaken to investigate the influence of benzyladenine (BA) on growth and metabolism of the freshwater microalga Chlorella vulgaris cultures subjected to sodium chloride stress. The interactive effects of salinity (2, 5, and 15 ppt NaCl) and/or benzyladenine (BA, 10 ppm) on growth, pigments composition, carbohydrate constituents, protein content, amino acids concentratio...

Less than 0.5% of total water in the world is available for human consumption and agriculture. The major part of the world's water is saline and salinity in soils interferes in germination of seeds and the posterior development of the plant. In order to increase the osmotolerance of tomato, seedlings were associated with Azospirillum brasilense Cd, Azospirillum brasilense Cd transformed bacteri...

Molecular karyotypes for six strains of four Chlorella species were obtained by using an alternating-field gel electrophoresis system which employs contour-clamped homogenous electric fields (CHEF). The number and migration pattern of the chromosomal DNA molecules varied greatly from strain to strain: for example, nine separated chromosomes of C. ellipsoidea C87 ranged from 2.5 to 6.5 megabase ...

In recent years, biosorption is being considered as an environmental friendly technology for the recovery of rare earth metals (REE). This study investigates the optimal conditions for the biosorption of neodymium (Nd) from an aqueous solution derived from hard drive disk magnets using green microalgae (Chlorella vulgaris). The parameters considered include solution pH, temperature and biosorbe...

This study was conducted to investigate the influence of biochanin A (isoflavone characterised by estrogenic activity) upon the growth expressed as number of cells and the content of chlorophyll a and b, total carotenoids, reducing sugars, water-soluble proteins and nucleic acids (DNA, RNA) in the unicellular green alga Chlorella vulgaris, as an experimental model. Biochanin A in a concentratio...

The green microalga Chlorella vulgaris has been widely recognized as a promising candidate for biofuel production due to its ability to store high lipid content and its natural metabolic versatility. Compartmentalized genome-scale metabolic models constructed from genome sequences enable quantitative insight into the transport and metabolism of compounds within a target organism. These metaboli...
