Fermented Chlorella vulgaris was examined for its effects on growth performance, cecal microflora, tibia bone strength, and meat qualities in commercial Pekin ducks. A total of three hundred, day-old male Pekin ducks were divided into three groups with five replicates (n = 20 ducklings per replicate) and offered diets supplemented with commercial fermented C. vulgaris (CBT(®)) at the level of 0...

The effect of sodium chloride on the photosynthetic electron transport chain was investigated in the freshwater green alga Chlorella vulgaris. It was found that the rate of oxygen evolution under steady state and flash light conditions diminished by increasing salt concentrations. Salt treatment of cells also decreased the fluorescence and delayed luminescence yields. However, the fluorescence ...

1. The delayed light emission of Chlorella pyrenoidosa over the wave length range 400 to 950 mmicro has been investigated. 2. Emission of delayed light is confined to the range 600 to 800 mmicro. 3. To the precision with which the low light intensities involved can be measured with the apparatus in these experiments, the emission spectrum of the delayed light is the same as the spectrum of the ...

Photosynthesis in Chlorella pyrenoidosa is inhibited by iodo-acetic acid and iodo-acetamide, both of which attack the Blackman reaction. Since acetamide is without effect, the iodo-acetyl radical must be responsible. The study of the action of the acid is complicated by the fact that its ions penetrate slowly, if at all, so that negative results with this agent are without significance unless p...

Chlorella is the most cultivated eukaryotic green micro alga, as it is widely used as a health food and feed supplement, as well as in the pharmaceutical and cosmetics industry. It contains proteins, carotenoids, lipids, immunostimulator compounds, polysaccharides, vitamins, antioxidants and minerals. The growth of algae is a function of many factors, including nutrients, pH, salinity, temperat...

The basic requirements for high-density photoautotrophic microalgal cultures in enclosed photobioreactors are a powerful light source and proper distribution of light, efficient gas exchange, and suitable medium composition. This article introduces the concept of balancing the elemental composition of growth medium with biomass composition to obtain high-density cultures. N-8 medium, commonly u...

When S-deficient cells of Chlorella cllipsoidea were incubated in radio-sulfate in light or in aerobic darkness for 1 hour, equal amounts of radioactivity were found in sulfolipid and glutathione but none was detected in sulfoquinovosyl glycerol which is one of the major S-compounds in this alga. No assimilation of radiosulfate was observed under anaerobic darkness.To elucidate the function of ...
