Kieft, Brandon; et al. (2021): Phytoplankton exudates and lysates support distinct microbial consortia with specialized metabolic and ecophysiological traits

Kieft, Brandon; Li, Zhou; Bryson, Samuel; Hettich, Robert L.; Pan, Chongle; Mayali, Xavier; Mueller, Ryan S. (2021): Phytoplankton exudates and lysates support distinct microbial consortia with specialized metabolic and ecophysiological traits. In Proceedings of the National Academy of Sciences of the United States of America 118 (41). DOI: 10.1073/pnas.2101178118.

"Blooms of marine phytoplankton fix complex pools of dissolved organic matter (DOM) that are thought to be partitioned among hundreds of heterotrophic microbes at the base of the food web. While the relationship between microbial consumers and phytoplankton DOM is a key component of marine carbon cycling, microbial loop metabolism is largely understood from model organisms and substrates. Here, we took an untargeted approach to measure and analyze partitioning of four distinct phytoplankton-derived DOM pools among heterotrophic populations in a natural microbial community using a combination of ecogenomics, stable isotope probing (SIP), and proteomics. Each 13C-labeled exudate or lysate from a diatom or a picocyanobacterium was preferentially assimilated by different heterotrophic taxa with specialized metabolic and physiological adaptations."

Video: Biomass Harvesting and Storage (AirMiners Event Series)

"We at AirMiners continuously strive to find novel, potentially impactful methods of carbon removal; our panel event on Biomass Harvest and Storage (BHS) represents just that! Problem: Since biomass is essentially photosynthetically captured carbon, when plant biomass dies and decomposes, it releases its carbon back to the atmosphere as CO2 and other GHGs via the Carbon Cycle. Solution: BHS is a CDR method in which dead or live biomass is harvested via collection or selective cutting, and then either buried underground or stored aboveground to slow or prevent biomass from decomposing. BHS thus provides a way to break the Carbon Cycle and remove atmospheric CO2."

Call for Nominations: Designing a Framework for Responsible Research to Evaluate CO2 Removal and Environmental Effects of Sinking Marine Biomass: Call for Nominations to an Expert Working Group

Deadline: 22. August 2021

"Ocean Visions and its partner, the Monterey Bay Aquarium Research Institute (MBARI), announce a call for self-nominations from scientists, engineers, technologists, entrepreneurs, environmental managers, conservationists, and other relevant actors to join a working group to develop a framework for responsible research regarding the fate and environmental impacts of sinking marine biomass (seaweed) to the deep ocean for carbon dioxide removal."

Energy Transitions Commission (2021): Bioresources within a Net-Zero Emissions Economy: Making a Sustainable Approach Possible

Energy Transitions Commission (2021): Bioresources within a Net-Zero Emissions Economy: Making a Sustainable Approach Possible.

"In its new report Bioresources within a Net-Zero Emissions Economy, the Energy Transitions Commission (ETC) makes plain that, while bioresources are in principle renewable, not all forms of biomass use are beneficial from an environmental perspective: not all biomass is ‘good’ biomass."

Shahbaz, Muhammad; et al. (2021): A comprehensive review of biomass based thermochemical conversion technologies integrated with CO2 capture and utilisation within BECCS networks

Shahbaz, Muhammad; AlNouss, Ahmed; Ghiat, Ikhlas; Mckay, Gordon; Mackey, Hamish; Elkhalifa, Samar; Al-Ansari, Tareq (2021): A comprehensive review of biomass based thermochemical conversion technologies integrated with CO2 capture and utilisation within BECCS networks. In Resources, Conservation and Recycling 173, p. 105734. DOI: 10.1016/j.resconrec.2021.105734.

"The potential for thermochemical conversion processes (combustion, gasification, pyrolysis, and liquefaction) to manifest within BECCS systems is analysed, in addition to their integration potential with carbon dioxide capture methods. Outcomes suggest that gasification and combustion processes when integrated with CO2 capture and storage (CCS), within combine heat and power (CHP) configurations, biomass integrated gasification combine cycle (BIGCC) and chemical looping cycle (CLC) are mature technologies."

Forsberg, C. W.; et al. (2021): Replacing liquid fossil fuels and hydrocarbon chemical feedstocks with liquid biofuels from large-scale nuclear biorefineries

Forsberg, C. W.; Dale, B. E.; Jones, D. S.; Hossain, T.; Morais, A.R.C.; Wendt, L. M. (2021): Replacing liquid fossil fuels and hydrocarbon chemical feedstocks with liquid biofuels from large-scale nuclear biorefineries. In Applied Energy 298, p. 117225. DOI: 10.1016/j.apenergy.2021.117225.

"We describe a system to replace liquid fossil fuels with drop-in biofuels including gasoline, diesel and jet fuel. Because growing biomass removes carbon dioxide from the air, there is no net addition of carbon dioxide to the atmosphere from burning biofuels."
