Abstract:
Microalgae are increasingly recognized as an important component of the biofuel, bioremediation, medicinal, and cosmetic industries. Even though microalgal technologies have many applications, economic barriers prevent them from being commercialized everywhere, notably in low-value, high-volume industries like biofuel. The wide application of microalgae in various industries has led researchers to develop advanced methods for microalgae cultivation. However, microalgae biomass production remains insufficient, and appropriate products to meet the rising demand from diverse industries continues to represent a notable bottleneck. Using a suitable microalgae growth system that leverages free or inexpensive resources, like wastewater for nutrients, solar energy for light, flue gas for CO2, and waves for mixing, is one of the main strategies for producing microalgae biomass. Raceways, tanks, ponds, and photobioreactors are just a few choices for growing microalgae. In the present study, we assessed the OD680 of microalgae Synechococcus elongatus and Chlorella sorokiniana in an external circular looped Photobioreactor using Algal Data Analyzer (ADA). ADA is an open-source Python software package that performs the growth analysis of microalgae three commercial PBR and supports manually adding data. ADA allows the production of easy and quick plots and can analyze multiple growth curves. The biomass of both strains was assessed, and maximum biomass productivity was found to be 1.32 g/L/d for Synechococcus elongatus and 0.52 g/L/d for Chlorella sorokiniana. ADA provides a standardized method for analyzing the algal growth data and can be employed in future studies for data analysis and comparing different PBRs.
