Fermentation Result Colors

What is the appearance of a positive result for fermentation with acid and no gas end products?

The appearance of a positive result for fermentation with acid and no gas end products is yellow color.

When certain substances undergo fermentation, they produce different end products. In the absence of gas production, the color change can be used to indicate a positive result. For example, a yellow color change can occur when glucose is fermented to produce acids like lactic acid or acetic acid.

The appearance of yellow color in this context is a key indicator of successful fermentation with acid and no gas end products.
