BACKGROUND The biomass yield of Chlorella PY-ZU1 drastically increased when cultivated under high CO2 condition compared with that cultivated under air condition. However, less attention has been given to the microalgae photosynthetic mechanisms response to different CO2 concentrations. The genetic reasons for the higher growth rate, CO2 fixation rate, and photosynthetic efficiency of microalga...

The toxicity of As(V) and As(III) to two axenic tropical freshwater microalgae, Chlorella sp. and Monoraphidium arcuatum, was determined using 72-h growth rate-inhibition bioassays. Both organisms were tolerant to As(III) (72-h concentration to cause 50% inhibition of growth rate [IC50], of 25 and 15 mg As[III]/L, respectively). Chlorella sp. also was tolerant to As(V) with no effect on growth ...

Microalgae exert several beneficial effects on plants. The present study aimed to evaluate the effect of Chlorella sorokiniana biomass as a biostimulator seed germination maize cultivar LG 36790. Germitest® paper tests were performed in greenhouse. treatments studied were:1) water (control), 2) 5% sorokiniana; 3) washed biomass, and 4) micronutrient urea solutions. On paper, treatment showed hi...

Eichhornia crassipes (Mart) Solms is an invasive weed known to out-compete native plants and negatively affect microbes including phytoplankton. The spread and population density of E. crassipes will be favored by global warming. The aim here was to identify compounds that underlie the effects on microbes. The entire plant of E. crassipes was collected from El Zomor canal, River Nile (Egypt), w...

Chlorella is a green eukaryotic microalgae ( vulgaris ). The microscopic cell spherical, 2–10 µm in diameter. This one of the most important and promising for biomass production. contains pool biologically active substances: about 50% protein (including essential amino acids); complex unsaturated fatty acids Omega-3); vitamins A, B1, B2, B3, B5, B6, E; as well macro- micronutrients health. crea...

Microalgae are considered one of the most efficient and environmentally friendly ways for carbon dioxide fixation. The bubbles play an important role in analyzing radiation transfer photobioreactors during microalgae growth. Herein, Chlorella sp. Scenedesmus obliquus were cultured airlift flat plate photobioreactor evaluated temporal evolution characteristics. A one-dimensional model on time-de...

Microalgae are an enormous biomass used for fortification in foods that represent a promising source of protein. Enrichment baked with microalgae is challenge its textural and structural impacts. In this study, dough rheology, physical, sensorial properties low-fat cookies Chlorella vulgaris at various concentration (0.5, 1.5 3.0 %) were evaluated. Dry matter (93.20 to 94.89, %), protein (5.55 ...
