In photosynthesis, a very small amount of the solar energy absorbed is transformed into chemical energy, while the rest is wasted as heat and fluorescence. This excess energy can be harvested through biophotovoltaic platforms to generate electrical energy. In this study, algal biofilms formed on ITO anodes were investigated for use in the algal biophotovoltaic platforms. Sixteen algal strains, ...

A partial cDNA clone coding for the haem-binding domain of NADH:nitrate reductase (EC 1.6.6.1) (NR) from the unicellular green alga Chlorella vulgaris has been isolated, sequenced and expressed. A 1.2 kb cDNA (pCVNR1) was isolated from a lambda gt11 expression library produced from polyadenylated RNA extracted from nitrate-grown Chlorella cells. pCVNR1 hybridized to a 3.5 kb mRNA transcript tha...

ریز جلبک کلرلا ولگاریس chlorella vulgaris به منظور تولید زیست توده و حذف نیتروژن و فسفات در فاضلاب شهری کشت گردید. تغییرات زیست توده، غلظت نیترات، آمونیوم و فسفات اندازه گیری شد. بیشترین مقدار تولید زیست توده 2 گرم وزن خشک در لیتر بود. مقدار زیست توده با کاهش مقدار نیتروژن (p

The effect of light conditions on the growth of green algae Chlorella vulgaris and cyanobacteria Gloeothece membranacea was investigated by filtering different wavelengths of visible light and comparing against a model daylight source as a control. Luminescent acrylic sheets containing violet, green, orange or red dyes illuminated by a solar simulator produced the desired wavelengths of light f...

Effect of docosahexaenoic acid (DHA) [22: 6(n-3)]-fortified Chlorella oil fraction on radial maze performance was studied in aged mice. Male ICR mice aged 9 months were fed a diet containing 2 g DHA-fortified Chlorella oil fraction/100 g diet or normal diet (Control group) for 2 months. Two months after the start of feeding, the mice were tested for learning ability related to 2 types of memory...

The freshwater microalgae Chlorella sp. and Vulgaris were cultured in a laboratory-scale photobioreactor their growth kinetics total lipid production evaluated. These species grown modified Conway medium, with an 8:16 photoperiod mechanical air ventilation. evaluation time was twenty days, the cell density determined daily using Neubauer chamber by optical spectrophotometry at 685 nm. rate perc...

The responses of two species of microalgae, Chlorella sorokiniana and Chlorella zofingiensis, were compared regarding their morphological and biochemical properties under photoautotrophic and mixotrophic conditions. These microalgae were cultured under both conditions, and their crude ethanolic extracts were examined for their pigment and total phenolic contents. In addition, the microalgae's a...

The fluorescence transient of Chlorella pyrenoidosa, excited by saturating light absorbed mainly by system II, has a dip D between the peak I at 75 msec and the large peak P at 400 msec (the times depend on light intensity). This dip is observed in aerobic cells and in anaerobic cells where it is prominent. In anaerobic cells, the I-D decline is hastened almost equally by absorption of either 7...

Nano ZnO is currently used in the rubber, electronics, electrical appliances, enamel, cosmeticsand medical industry. Whereas most studies have used the ecological toxicity of nanoparticles, the toxic effects of nanoparticles in diet is not extensively explored. Because the algaeare at the base of the food chain, any change in their density, biomass and population, wouldaffect the food chain in ...

Urea metabolism was studied with nitrogen-starved cells of Chlorella vulgaris Beijerinck var. viridis (Chodat), a green alga which apparently lacks urease. Incorporation of radioactivity from urea-(14)C into the alcohol-soluble fraction was virtually eliminated in cell suspensions flushed with 10% CO(2) in air. This same result was obtained when expected acceptors of urea carbon were replenishe...
