Solid-state fermentation: an alternative for continuous and discontinuous production of bioactive compounds with biological activity

Bioactive compounds are secondary metabolites widely studied for their benefits to human health. They are distributed in various fruit, vegetable, and plant peels. The application of sustainable techniques for the extraction of these compounds is being implemented, assisted extraction by solid-state fermentation is a sustainable and effective alternative for the recovery of bioactive compounds by using agro-industrial waste as a raw material for extraction, this being a green process, easy for implementation, and it has low water and energy consumption. This research presents the biological properties of some of the most used bioactive compounds in the industry, as well as the advantages and factors that influence solid-state fermentation and the different processes for their recovery and/or production. The production of bioactive compounds using both continuous and discontinuous processes come with unique advantages and challenges. The choices between these methods depend on specific production objectives, scalability needs, and the availability of resources. As a result, ongoing advancements are refining these methods, enabling more sustainable and efficient production of bioactive compounds.
