Type of post: NEWS IN BRIEF. Yield10 Bioscience has announced recent advances in the development of Camelina as a platform for the production of PHA (polyhydroxyalkanoates) bioplastics directly in the seed. Press release: “ Yield10 Bioscience Announces Recent Advances in the Development of Camelina as a Production Platform for PHA Bioplastic ”, 08/03/2022. Figure 1. Yield10 Bioscience announces advances in the production of PHA directly in Camelina seeds Those advancements include: - 2021 Field Test results: In 2021 Yield10 tested the two prototype PHA (C3014 and C3015) producing spring Camelina lines at sites in the U.S. and Canada. Results showed that C3015 lines produced PHA at the 6 percent level as measured as a percent of seed weight, consistent with results observed in field tests conducted in 2020. - 2022 Seed Scale up Plan: Field work completed during 2021 supports the Yield10’s decision to begin seed scale up of prototype PHA spring Camelina lines. Permitting is underw

Type of post: NEWS IN BRIEF. Carbon transformation company Twelve and biotechnology company LanzaTech have transformed CO2 emissions into ethanol as a part of an ongoing research and development partnership. Press release: “ Twelve and LanzaTech Partner to Create Ethanol From CO2 ”, 03/03/2022. Related post: “ LanzaTech and Twelve partner to transform CO2 emissions into polypropylene ”, 02/09/2021. Figure 1. LanzaTech and Twelve join forces to transform CO2 emissions into ethanol Twelve and LanzaTech are eliminating fossil fuels from ethanol production by converting CO2 to CO through Twelve’s carbon transformation technology, and subsequently using LanzaTech’s small Continuous Stirred Tank Reactor (CSTR) to convert CO to ethanol. This approach is highly scalable and could ultimately produce ethanol at an industrial scale, while simultaneously eliminating CO2 emissions. In Fall 2021, Twelve and LanzaTech also announced plans to develop polypropylene from CO2 with a grant from Impact

English version PLATAFORMAS DE BIORREFINERÍA Concepto - La lignina es un polímero amorfo natural, que actúa como el adhesivo esencial que proporciona a las plantas su integridad estructural. La naturaleza produce lignina mediante la polimerización deshidrogenativa enzimática del alcohol coniferílico (común en las maderas blandas), el alcohol siringílico (común en las maderas duras) y el alcohol cumarílico (común en las gramíneas). - De los tres polímeros naturales principales que componen las plantas comunes (celulosa, lignina y hemicelulosa), la lignina es la segunda fracción más abundante después de la celulosa. - La lignina se basa en unidades aromáticas. La estructura de la lignina es compleja y cambia según la fuente de biomasa. Está compuesto por unidades ramificadas aleatoriamente de fenilpropenilo (C9). Los bloques de construcción de fenilpropenilo, guayacoles y siringoles, están conectados a través de enlaces carbono-carbono y carbono-oxígeno (éter). Las unidades conectadas

Versión en Español BIOREFINERY PLATFORMS Concept - Lignin is a natural amorphous polymer, which acts as the essential glue that gives plants their structural integrity. Nature produces lignin by the enzymatic dehydrogenative polymerization of coniferyl alcohol (common in softwoods), syringyl alcohol (common in hardwoods) and coumaryl alcohol (common in grasses). - Of the three major natural polymers that make up ordinary plants (cellulose, lignin and hemicellulose), lignin is the second most abundant fraction behind cellulose. - Lignin is based on aromatic units. The structure of lignin is complex and changes according to biomass source. It is composed of phenylpropenyl (C9) randomly branched units. The phenylpropenyl building blocks, guaiacols and syringols, are connected through carbon-carbon and carbon-oxygen (ether) bonds. Trifunctionally linked units provide numerous branching sites and alternate ring units. - Currently, most lignin on the market is a by-product from the pulp an
