INDUSTRIAL PLANT FOR PRODUCTION OF Spirulina sp. LEB 18

Abstract

Biorefineries based on microalgae produce biofuels and co-products with added value. Microalgae mainly require water, carbon dioxide and sunlight for growth. The bioproducts of the cultivation of these microorganisms can be fully used in a microalgae photobiorefinery. The objective of this work was to study the behavior of physico-chemical variables and kinetic and biological responses in industrial cultivation of Spirulina sp. LEB 18, aiming at the operation of a microalgal photobiorefinery. The maximum specific growth rate (0.133 1/d), the minimum generation time (5.2 d) and maximum productivity (14.9 g/m².d) were obtained in the first 9 d of microalgae growth. The maximum biomass concentration (1.64 g/L) was obtained in 37 d of cultivation. The highest levels of carbohydrates, proteins and lipids in the biomass were 10.6, 57.0 and 11.7%, respectively. The plant monitoring demonstrated that the microalgae produced biomass with high quality for application as biofuels, energy, health and nutrition human.

Pilot scale production, extraction and purification of a thermostable phycocyanin from Synechocystis sp. PCC 6803

“…Based on the Te-PC content in this study, the estimated Te-PC productivity of the TeBACD strain in an optimised flat-panel PBR (i.e. 13.9 mg PC L -1 d -1 ) could match that of A. platensis grown in open raceway ponds (6–15 mg PC L -1 d -1 ) ( Uebel et al, 2019 ). Further optimisations of the growth medium may also provide additional increases in PC productivity ( Zuorro et al, 2021 ).…”

Effect of Spirulina platensis on the quality and antioxidants characteristics of ice cream

“…Spirulina is recognized as a safe and non-toxic food supplement according to the Food and Drug Administration (FDA). The assessment of FDA is based on the nutritional and antioxidant properties of spirulina due to its chemical composition and biological active ingredients [5].…”
