The laboratory strain of , PAO1, activates genes for catabolism of adenosine using quorum sensing (QS). However, this strain is not well-adapted for growth on adenosine, with doubling times greater than 40 h. We previously showed that when PAO1 is grown on adenosine and casein, variants emerge that grow rapidly on adenosine.

- The study examined lipid accumulation in the marine diatom Phaeodactylum tricornutum under various stresses, emphasizing that nitrogen limitation is crucial for lipid buildup, with other conditions aiding in this process.
- Rankings of lipid levels based on different treatments showed that bicarbonate addition led to the highest lipid accumulation, followed by acetate supplementation and alkaline stress.
- Molecular analyses revealed significant metabolic pathways linked to lipid accumulation, including bicarbonate transport and phospholipid repurposing, laying the groundwork for future research on diatom nutrient cycling and lipid metabolism.
