Cyanobacteria newly isolated from marine volcanic seeps display rapid sinking and robust, high-density growth.

Unlabelled: Cyanobacteria are photosynthetic organisms that play important roles in carbon cycling and are promising bioproduction chassis. Here, we isolate two novel cyanobacteria with 4.6Mbp genomes, UTEX 3221 and UTEX 3222, from a unique marine environment with naturally elevated CO₂.

Alternative carbon sources for the production of plant cellular agriculture: a case study on acetate.

Plant cellular agriculture aims to disrupt the way plant derived products are produced. Plant cell cultures are typically grown with sucrose as the primary carbon and energy source, but alternative carbon sources may have advantages over sucrose including less strain on food systems, lower costs, and more sustainable sourcing. Here we review carbon and energy sources that may serve as alternatives to sucrose in the cultivation of plant cell cultures.

A hybrid inorganic-biological artificial photosynthesis system for energy-efficient food production.

Artificial photosynthesis systems are proposed as an efficient alternative route to capture CO to produce additional food for growing global demand. Here a two-step CO electrolyser system was developed to produce a highly concentrated acetate stream with a 57% carbon selectivity (CO to acetate), allowing its direct use for the heterotrophic cultivation of yeast, mushroom-producing fungus and a photosynthetic green alga, in the dark without inputs from biological photosynthesis. An evaluation of nine crop plants found that carbon from exogenously supplied acetate incorporates into biomass through major metabolic pathways.
