[PMID: 37598949 DOI: 10.1016/j.chemosphere.2023.139856] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/27/2023] [Revised: 06/19/2023] [Accepted: 08/15/2023] [Indexed: 08/22/2023]
Abstract
Microalgae are the main source of third-generation biofuels because they have a lipid content of 20-70%, can be abundantly produced and do not compete in the food market besides other benefits. Biofuel production from microalgae is a promising option to contribute for the resolution of the eminent crisis of fossil energy and environmental pollution specially in the transporting sector. The choice of lipid extraction method is of relevance and associated to the algae morphology (i.e., rigid cells). Therefore, it is essential to develop suitable extraction technologies for economically viable and environment-friendly lipid recovery processes with the aim of achieving a commercial production of biofuels from this biomass. This review presents an exhaustive analysis and discussion of different methods and processes of lipid extraction from microalgae for the subsequent conversion to biodiesel. Physical methods based on the use of supercritical fluids, ultrasound and microwaves were reviewed. Chemical methods using solvents with different polarities, aside from mechanical techniques such as mechanical pressure and enzymatic methods, were also analyzed. The advantages, drawbacks, challenges and future prospects of lipid extraction methods from microalgae have been summarized to provide a wide panorama of this relevant topic for the production of economic and sustainable energy worldwide.

Cabrera-Capetillo CA, Castillo-Baltazar OS, Petriz-Prieto MA, Guzmán-López A, Valdovinos-García EM, Bravo-Sánchez MG. Simulation and Economic Analysis of the Biotechnological Potential of Biomass Production from a Microalgal Consortium. Mar Drugs 2023; 21:321. [PMID: 37367646 DOI: 10.3390/md21060321] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2023] [Revised: 05/24/2023] [Accepted: 05/25/2023] [Indexed: 06/28/2023] Open
Abstract
The biomass of microalgae and the compounds that can be obtained from their processing are of great interest for various economic sectors. Chlorophyll from green microalgae has biotechnological applications of great potential in different industrial areas such as food, animal feed, pharmaceuticals, cosmetics, and agriculture. In this paper, the experimental, technical and economic performance of biomass production from a microalgal consortium (Scenedesmus sp., Chlorella sp., Schroderia sp., Spirulina sp., Pediastrum sp., and Chlamydomonas sp.) was investigated in three cultivation systems (phototrophic, heterotrophic and mixotrophic) in combination with the extraction of chlorophyll (a and b) on a large scale using simulation; 1 ha was established as the area for cultivation. In the laboratory-scale experimental stage, biomass and chlorophyll concentrations were determined for 12 days. In the simulation stage, two retention times in the photobioreactor were considered, which generated six case studies for the culture stage. Subsequently, a simulation proposal for the chlorophyll extraction process was evaluated. The highest microalgae biomass concentration was 2.06 g/L in heterotrophic culture, followed by mixotrophic (1.98 g/L). Phototrophic and mixotrophic cultures showed the highest chlorophyll concentrations of 20.5 µg/mL and 13.5 µg/mL, respectively. The simulation shows that higher biomass and chlorophyll production is attained when using the mixotrophic culture with 72 h of retention that we considered to evaluate chlorophyll production (a and b). The operating cost of the entire process is very high; the cultivation stage has the highest operating cost (78%), mainly due to the high energy consumption of the photobioreactors.

Production of Biodiesel from Underutilized Algae Oil: Prospects and Current Challenges Encountered in Developing Countries. BIOLOGY 2022; 11:biology11101418. [PMID: 36290321 PMCID: PMC9599019 DOI: 10.3390/biology11101418] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/04/2022] [Revised: 09/22/2022] [Accepted: 09/25/2022] [Indexed: 11/17/2022]
Abstract
Simple Summary The production of biofuel, especially biodiesel, from algae oil receives little attention in developing countries due to poor enlightenment on biotechnology, high poverty rates, and poor funding of research. This study focuses on finding a better understanding of the evolving prospects and current challenges facing biodiesel production from algae oil in developing nations. Interestingly, several species of microalgae that can serves as sustainable feedstocks for biodiesel production have been identified in developing nations. It is evident that microalgae oil has physicochemical properties that qualifies it for the production of biodiesel, with fuel properties that meet ASTM and EN standards. Abstract Biofuel continues to thrive as an outstanding source of renewable energy for the global community. Several resources have been proposed as sources of feedstocks for biofuel; however, some of these have shortcoming. The use of biomass such as algae as a source of feedstock for biofuel is undoubtedly sustainable and green. Unfortunately, the use of algae oil for biodiesel production is underutilized in developing countries. Therefore, this study focuses on finding a better understanding of the evolving prospects and current challenges facing biodiesel production from algae oil in developing countries. The study revealed that less attention is given to the use of algae oil in biodiesel production due to poor enlightenment on biotechnology, high poverty rates, government policies, business strategies, and poor funding of research. Interestingly, several species of algae that can serve as sustainable feedstocks for biodiesel production have been identified in developing countries. It is evident that algae oil has properties that qualify it for the production of biodiesel with fuel properties that meet both the American Society for Testing and Materials and the European standards for biodiesel.
