Enzymes usually related to postbiotics have antioxidant results.Cell wall fragments: Items of bacterial cell partitions.Quick-chain fatty acids (SCFAs): These are produced when intestine microbiota ferments (breaks down) carbohydrates in plant meals. Frequent SCFAs embody acetic acid, propionic acid, and butyric acid.Bacterial lysates: These are created by breaking down Gram-positive and Gram-negative micro organism generally discovered within the setting.Metabolites produced by intestine microbiota: These are molecules naturally created by intestine microbiota.
