The fatty acid metabolism of Chlorella vulgaris
Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1965Abstract 1. 1. Transferring Chlorella vulgaris from media containing organic carbon compounds to phosphate buffer (pH 7.4) under illumination, causes a rapid increase in the content of linoleic , α-linolenic acids. 2. 2. In media containing carbohydrate little 14 CO 2 is fixed into long chain fatty acids. 3. 3.

Dispersed ozone flotation of Chlorella vulgaris
Bioresource Technology, 2010Flotation separation of Chlorella vulgaris, a species with excellent potential for CO(2) capture and lipid production, was studied using dispersed ozone gas. Pure oxygen aeration did not yield flotation. Conversely, applying ozone effectively separation algae from broth through flotation. The ozone dose applied for sufficient algal flotation is

Autoinhibitor Production by Chlorella vulgaris
American Journal of Botany, 1964Filtrates from certain liquid cultures of Chlorella vulgaris (Columbian strain) developed sufficient peroxide content, after a few days’ storage, to inhibit further growth of Chlorella when they were used to prepare fresh culture media. Similar inhibition was observed when Chlorella was cultured in media containing various added organic peroxides ...

Coagulation-membrane filtration of Chlorella vulgaris
Bioresource Technology, 2012Filtration-based separation of Chlorella vulgaris, a species with excellent potential for CO(2) capture and lipid production, was investigated using a surface-modified hydrophilic polytetrafluoroethylene (PTFE) membrane. Coagulation using polyaluminum chloride (PACl) attained maximum turbidity removal at 200 mg L(-1) as Al(2)O(3).

Biosynthesis of Chlorophylls a and b in Chlorella vulgaris
Nature, 1960WE have shown that both carbon atoms of glycine were incorporated into chlorophyll a when Chlorella vulgaris was incubated with 14C-glycine for a period of 1 hr. During this period no carbon-14 from the carboxyl group could be detected in chlorophyll b, whereas the incorporation of the carbon from the methylene group was several times higher than in ...

Fluorescence studies on deuterated Chlorella vulgaris
Biochimica et Biophysica Acta (BBA) - Biophysics including Photosynthesis, 1966Abstract Chlorella vulgaris grown in 99.8% heavy water show absorption spectra similar to the absorption spectra shown by those grown in ordinary water; there appears to be a minor shift of about 1 mμ towards shorter wavelengths in the blue and the red absorption bands, and a slight increase in chlorophyll b to a and carotenoids to chlorophyll

An auto-flocculation strategy for Chlorella vulgaris
Biotechnology Letters, 2014Extracellular polymeric substances (EPS) excreted by microalgae are effective for microalgal flocculation. An auto-flocculation strategy was conducted by adding adequate glycine into the medium, stimulating EPS secretion to achieve auto-flocculation, and recycling the supernatant medium for further cultivation.

Microcalorimetric studies on the metabolism of Chlorella vulgaris
Chemosphere, 2000The heat output of the non-growth metabolism of Chlorella vulgaris has been determined using an LKB-2277 BioActivity Monitor. The experimental results indicate that there is a turn-point on the metabolic thermogenic curves, which can be divided into two parts, an early phase and a later phase. For the early phase, there is a linear relationship between

Giornale di batteriologia, virologia ed immunologia, 1977
The uptake, accumulation and loss of traces of radiocobalt present in the culture medium by a green alga, Chlorella vulgaris, were studied. The trace quantities of the radionuclide employed had no effect on the growth of the algal population. The uptake is related to the number of cells present and to the temperature of the culture medium; it is not ...

Gold uptake by Chlorella vulgaris
Journal of Applied Phycology, 1995This paper describes a study on the uptake of gold (III) ions by viable and treated cells of the unicellular alga, Chlorella vulgaris. Inactivating the algal cells by various physical/chemical treatments resulted in a considerable enhancement in the uptake capacity over the pristine cells.
