mixed culture

Mixed culture refers to a group of different microbial species or strains growing together in the same environment, such as in food fermentation, environmental samples, or laboratory cultures. These diverse microorganisms interact, which can influence the flavor, texture, safety, and overall quality of the final product. Unlike pure cultures, which contain only one microorganism, mixed cultures mimic natural or traditional processes where multiple microbes contribute to complex outcomes. Managing mixed cultures requires understanding their interactions to achieve desired results, whether in food production, biotechnology, or research.
