The Performance of Microalgae (Nannochloropsis sp., Tetraselmis sp. and Dunaliella sp.) on White Shrimp (Litopenaeus vannamei) Wastewater Cultivation Media

Journal of Aquaculture and Fish Health, 2021
Microalgae have an important role in supporting the development of aquaculture because it can be used as natural feed. However, its culture requires an expensive cost because of the nutrient media. To reduce the cost, the media can be replaced by using wastewater from white shrimp (Litopenaeus vannamei) culture.

Enhancing the electrocoagulation process for harvesting marine microalgae (Tetraselmis sp.) using interdigitated electrodes

Journal of Environmental Management, 2021
Marketable value of algal biomass has been increasing in recent years due to its wide range of applications. This study investigates the performance of a novel cylindrical interdigitated electrode array in electrocoagulation for the harvesting of marine microalgae (Tetraselmis sp.). The new electrode array is expected to exert a dielectrophoretic (DEP)

The Effect of Various Salinities and Light Intensities on the Growth Performance of Five Locally Isolated Microalgae [Amphidinium carterae, Nephroselmis sp., Tetraselmis sp. (var. red pappas), Asteromonas gracilis and Dunaliella sp.] in Laboratory Batch Cultures

Journal of Marine Science and Engineering, 2021
After a 1.5-year screening survey in the lagoons of Western Greece in order to isolate and culture sturdy species of microalgae for aquaculture or other value-added uses, as dictated primarily by satisfactory potential for their mass culture, five ...

Effect of 4 microalgal diets on the proximal composition, chlorophyll concentration, and total carotenoid content in Artemia franciscana

Ciencias Marinas, 2023
Microalgae are the primary source of food for Artemia franciscana. In turn, Artemia serve as live food for various species in culture. The chemical composition of Artemia is of great importance because it affects the nutritional quality of the organisms ...

Outdoor turbidostat culture of the marine microalga Tetraselmis sp.

Aquaculture Research, 1994
. Biomass productivity, photosynthetic efficiency and fatty acid profiles of the marine microalga Tetraselmis sp. in a turbidostat culture system using an outdoor photobioreactor are described. The maximum productivity depended on the units in which it was expressed; it reached 5·41 × 10−3 g/l/h in volumetric units, and 7·26g/m2/day in surface units ...

Biological activities and chemical composition of methanolic extracts of selected Autochthonous microalgae strains from the Red Sea [PDF]

, 2015
Four lipid-rich microalgal species from the Red Sea belonging to three different genera (Nannochloris, Picochlorum and Desmochloris), previously isolated as novel biodiesel feedstocks, were bioprospected for high-value, bioactive molecules.

Un inusual bloom de Tetraselmis sp. en la Bahía de Valparaíso, Chile [PDF]

Gayana. Botánica, 2012
A bloom of Tetraselmis sp. was observed during the first days of January of 2006 in the Valparaiso Bay (32° 57'S; 71° 33'W), producing green coloration of sea and exclusion of phytoplankton species. Previous blooms of Tetraselmis sp. have not been observed in this bay.

Modelling Tetraselmis sp. growth-kinetics and optimizing bioactive-compound production through environmental conditions [PDF]

Bioresource Technology, 2018
The aim of this study is to predict Tetraselmis cells growth-kinetic and to induce the synthesis of bioactive compounds (chlorophylls, carotenoids and starch) with high potential for biotechnological applications. Using the statistical criteria, the Baranyi-Roberts model has been selected to estimate the microalgae growth-kinetic values.

Phytoplankton Response to Different Light Colors and Fluctuation Frequencies

Frontiers in Marine Science, 2022
The natural environment of phytoplankton is variable in manifold ways. Light, as essential resource for photosynthetic phytoplankton, fluctuates in its intensity (quantity) as well as spectrum (quality) over great temporal scales in aquatic ecosystems ...
