Microalgae possess the remarkable ability to autotrophically grow, utilizing atmospheric carbon dioxide (CO2) for photosynthesis, thereby converting solar energy into chemical and releasing oxygen. This capacity makes them an effective tool mitigating industrial CO2 emissions. Mathematical models are crucial predicting microalgal growth kinetics thus assessing their potential as sequestration agents under controlled conditions. study innovatively evaluated effect of continuously supplying from winemaking processes on cultivation biomass production, demonstrating a novel approach both capture valorization valuable by-product. To analyze kinetics, three mathematical were employed: Logistic, First Order Plus Dead Time, Second Time. Optimal parameter values each model identified using hybrid search algorithm developed by our research group. First, integrated microvinification system was established, two microalgae species, Chlorella spp. (FAUBA-17) Desmodesmus spinosus (FAUBA-4), in conjunction with yeast fermenters. facilitated comparison these selecting most suitable candidate subsequent cultivation. A pilot-scale vertical column photobioreactor then constructed installed at Casimiro Wines boutique winery Angaco, San Juan, Argentina. After 15 days operation within photobioreactor, 1.04 ± 0.05 g/L 1.07 0.1 obtained Photobioreactors 1 2, respectively. process is unprecedented. These findings highlight producing high-value biomass, promoting establishment local biorefinery fostering circular economy sustainable social development.

Algae and derivatives are currently being recognized for their potential characteristics as attributes in aquafeeds. These include high protein content, optimum balance of essential amino acids fatty acids, trace minerals, vitamins, relatively low cost, which make them promising alternatives the diets farmed fish shrimp. The inclusion algae bioactive compounds provides natural sources growth promoters immunostimulants, improve immune system response mitigate disease outbreaks pathogen infections. However, too much substitution would result poor development feed utilization. Therefore, this chapter discusses forms types algae, use feed, pros cons aid achieving aquaculture sustainability scope practical implementation.

Microalgae-based CO2 capture has potential as an industrial-scale solution to climate change challenges while also amassing usable microalgae biomass. Computational fluid dynamics (CFD) can optimize extraction in growing systems, especially when paired with phytohormone-regulated growth. This paper examines the use of CFD predict flow, nutrient distribution, light intensity, and mass transfer microalgae-based which are crucial for improving photosynthetic efficiency fixing CO2. The focus is on how phytohormones, such auxins cytokinin, influence microalgal growth their subsequent involvement increasing carbon sequestration. Furthermore, this review discusses applications reactor design, where biological kinetics interact increase biomass yield. scaling up transitioning from laboratory industrial application possible integration computational experiment data enhance simulation precision addressed. assessment demonstrates CFD’s important tool sustainable fixation.
