Comparison of Biomass Productivity of the Microalgae, Tetraselmis sp. KCTC12236BP, in Polyvinyl Chloride Marine Photobioreactor and High Density Polyethylene Marine Photobioreactor

A novel horizontal photobioreactor for high-density cultivation of microalgae.

Microalgae are a promising source of biofuels and bioproducts, as they consume CO2 to grow, multiply quickly, and can be cultivated in wastewater and on marginal land. Development of low-cost and high-efficiency microalgal cultivation systems is important to the cost-competitiveness of algae. A floating horizontal photobioreactor (HBR) was developed that is inexpensive and scalable, as it is ma...

Biomass production, antioxidant capacity and removal of nitrate and phosphate by marine microalgae Tetraselmis tetrathele cultivated in food wastewater

This study was conducted to investigate the cultivation of Tetraselmis tetrathele in food effluent and the effect of different concentrations of effluent on specific growth rate, biomass, chlorophyll a, chlorophyll b, total carotenoids and comparing them with Conway medium. Meanwhile, in this experiment, the percentage of phosphate and nitrate removal from food effluent by T. tetrathelewas eval...

Novel photobioreactor for mass cultivation of microalgae

Microalgal biomass surface productivity optimization based on a photobioreactor model

In this paper we predict and optimize the biomass surface productivity of microalgae in continuous culture under a constant light source. Surface biomass is identified as a key variable for assessing productivity: we provide both a mathematical and intuitive explanation. For reaching maximal productivities, biomass surface concentration must be such that growth at the culture bottom (assuming a...

Control of the Microalgae Photosynthetic Growth in a Torus Photobioreactor

The microalgae have the ability to use CO2 as carbon source and, together with the solar energy, to biosynthesize various components, generating O2. They have a huge potential in various industrial applications such as the production of therapeutic and industrial metabolites, biofuels and environmental applications. The aim of this paper is to control the photosynthetic growth of the microalga ...
