Abstract
Extremophiles are microorganisms that thrive in extreme environments, such as high temperatures, high pressures, and acidic or alkaline conditions. These organisms have unique adaptations that allow them to survive in these harsh conditions, and they are of great interest to the food industry for a variety of applications. Extremophilic microorganisms produce a broad range of bioactive compounds, secondary metabolites, and value-added products such as flavors, food ingredients, and vitamins, therefore, making them widely applicable in the food and food processing industries. In food industries, one of the extremophiles, Rhodothermus marinus, which has been an excellent biocatalyst producing lipase as an enzyme, could be utilized to improve the aroma of food and add natural flavor to food. Others have emerged as a valuable resource for the food industry, offering solutions to food safety and preservation challenges, as well as opportunities for sustainable food processing. By harnessing the unique characteristics and enzymes of extremophiles, the food industry can improve product quality, develop novel fermentation processes, and enhance food safety. Extremophiles hold significant potential for use in the food industry; however, translating this potential into practical applications is fraught with several challenges. These challenges include specialized growth conditions, slow growth rate, and contamination risks. Advancing genetic, biotechnological, and engineering research will be pivotal in realizing the full potential of extremophiles. Ongoing exploration of these organisms is crucial not only for improving food production processes but also for fostering sustainability and driving innovation within the food industry.
