Where the Seagrass grows : 78 million tons of residual seagrass deposits accumulate annually on shorelines worldwide. These represent an untapped feedstock for fermentative single‐cell oil production, targeted at biofuel and oleochemical generation, without affecting the sensitive marine environment or compromising food security. In this study, seven beach‐cast samples of seagrass (related to Z. marina , Z. noltii , S. filiforme , P. australis , P. oceanic , and T. testudinum ) were collected from marine ecosystems around the world and tested for this purpose. The cover page explains the concept of sustainable bio‐oil production by the bio‐conversion of beach‐cast seagrass to lipids by using oily yeast fermentation. Beach‐accumulated seagrass is enzymatically liquefied into fermentable sugars, and the released sugars are then consumed by the yeast and stored as lipids within cell compartments. The oleaginous yeast Trichosporon oleaginous accumulate lipids intracellularly, which can subsequently be extracted and processed to biofuels.
