A Simple Method for the Mass Culture of Marine Algae

“…Since the fifties, multiple scientific studies have been carried out to obtain new energy sources from microalgae, with the purpose of replacing fossil fuels and causing less environmental impact (Dyer & Richardson, 1962;Ukeles, 1965). Microalgae also have a large amount of proteins, vitamins and minerals that can be used as raw material in the production of food supplements, organic fertilizers, pharmaceutical products and cosmetics for both human and animal consumption (Harun, Singh, Forde & Danquah, 2011;Mata, Martins & Caetano, 2010;Rawat, Ranjith-Kumar, Mutanda & Bux, 2011;Spolaore, Joannis-Cassan, Duran & Isambert, 2006).…”

In this article, the hydrodynamic behavior of a single-phase flow in various solar collectors with different cross sections (circular, octagonal, hexagonal and square), with same hydraulic diameter and longitudinal profile was analyzed. Secondary flow, pressure drop and shear stress were evaluated, because the photosynthetic efficiency and microalgae endurance depend on these properties. These parameters were reviewed at six different culture inlet rates in the collector (from 0,25 to 0,5m/s), emphasizing in the bends regions. A higher speed and agitation was present in the square solar collector, contrary to what happened to the circular one. Despite this, the circular solar collector remains the best option for the industrial implementation phase. However, the shear stress generated in the culture -as it passes through the 180° bend of the solar collector- affects the microalgae growth, as stated in the literature.

Natural phytoplankton of Cabo Frio area was grown in 42 m-deep artificially upwelled seawater enriched with increasing concentrations of nitrogen or phosphorus. Respective values allowing maximum biomass, maximum uptake of initial reserve and maximum yield coefficient are rather conflicting. Notwithstanding, respective values of 75 mig at 1 ' nitrogen and 5 g at 1' phosphorus, and therefore N:P = 15, appeared to be the best compromise for initial nutrient levels.
