Applications of the Microalgae and Its Bacterial Consortia in Detoxification and Bioproduction.

The wide metabolic diversity of microalgae, their fast growth rates, and low-cost production make these organisms highly promising resources for a variety of biotechnological applications, addressing critical needs in industry, agriculture, and medicine. The use of microalgae in consortia with bacteria is proving valuable in several areas of biotechnology, including the treatment of various types of wastewater, the production of biofertilizers, and the extraction of various products from their biomass. The monoculture of the microalga has been a prominent research model for many years and has been extensively used in the study of photosynthesis, sulphur and phosphorus metabolism, nitrogen metabolism, respiration, and flagellar synthesis, among others. Recent research has increasingly recognised the potential of -bacteria consortia as a biotechnological tool for various applications. The detoxification of wastewater using and its bacterial consortia offers significant potential for sustainable reduction of contaminants, while facilitating resource recovery and the valorisation of microalgal biomass. The use of and its bacterial consortia as biofertilizers can offer several benefits, such as increasing crop yields, protecting crops, maintaining soil fertility and stability, contributing to CO mitigation, and contributing to sustainable agricultural practises. -bacterial consortia play an important role in the production of high-value products, particularly in the production of biofuels and the enhancement of H production. This review aims to provide a comprehensive understanding of the potential of monoculture and its bacterial consortia to identify current applications and to propose new research and development directions to maximise their potential.
