This study investigates the scaling of photobioreactor productivity based on the growth of Nannochloropsis salina incorporating the effects of direct and diffuse light. The scaling and optimization of photobioreactor geometry was analyzed by determining the growth response of a small-scale system designed to represent a core sample of a large-scale photobioreactor. The small-scale test apparatu...

Beta-carotene is a valuable carotenoid in high demand as a natural food coloring agent, provitamin A, additive to cosmetics, and health food. It can be accumulated up to more than 10% of cellular dry weight of Dunaliella salina under carotenogenic conditions such as high irradiance, high temperature, high salt concentration and nutrient deficiency. High beta-carotene productivity in Dunaliella ...

hydroponics technique accompanied by adjustment of nutrient solution seems to optimize crop production and help in establishing sustainable agriculture. in recent years, the greenhouse production of cucumber has been increased in iran, however there are just a few proper nutrient solutions employed in growing the crop. in line with this, an experiment was conducted to find the effect of various...

in order to study the effect of macro nutrients on growth characteristics of two corn (zea maize l.) varieties (kws2360, ressuda pionee), an experiment was conducted in completely randomized design with three replications at growth room of crop physiology department of debrecen university. the treatments were nutrient solution free nitrogen (n), nutrient solution free phosphorus (p), nutrient s...

In Cambodia, cassava is mostly grown with little or no fertilizer inputs, but the magnitudes of nutrient balances are not known. This study was conducted to assess nutrient balances for cassava cultivation in Kampong Cham province in Northeast Cambodia. Forty five households in four cassava production zones were interviewed in relation to their cultural practices and crop residue management...
