genus of red algae
Quick Summary
Gracilaria is a genus of gelatinous red algae. These marine organisms are often found attached to other shore plants. Red algae, like Gracilaria, get their characteristic red or blue color from phycobilin pigments, which mask their chlorophyll.12
Several species within the Gracilaria genus are significant sources of agar-agar, a gelatin-like substance widely used as a culture medium for bacteria and fungi. This substance is also utilized industrially in products like puddings, toothpaste, ice cream, and preserves.12
