Used in microbiological testing to support the growth of specific microorganisms that metabolize inositol, allowing for the identification and quantification of inositol-utilizing bacteria in clinical, environmental, or food samples. Commonly applied in diagnostic laboratories to differentiate bacterial species based on their ability to ferment inositol, producing measurable acid byproducts. Also utilized in research settings to study carbohydrate metabolism pathways and assess microbial metabolic capabilities.
