Oleochemical Biorefinery

Abstract

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. ocean-ic, 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 enzy-matically 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 oleagi-nous accumulate lipids intracellularly, which can subsequently be extracted and processed to biofuels.

Bio‐economy for sustainable growth in developing countries: The case of oil palm in Malaysia and Indonesia

“…Conceptually, vertical integration between primary producers and advanced manufacturers allows the opening of alternative, on‐demand supply channels, especially when combined with technologies that can interconvert materials into a variety of chemicals, potentially optimizing the value chains. This allows broader access to different markets 20 …”
