In bacteria, mechanosensitive channels mediate extracellular release of osmolytes, including glutamate, functioning as safety valves upon osmotic downshift. In cyanobacteria, the role of mechanosensitive channels has not been completely elucidated. Recently, the glycogen-deficient ΔglgC mutant of Synechococcus elongatus PCC 7942 was found to release glutamate extracellularly, giving rise to a hypothesis that the role of mechanosensitive channels in cyanobacteria is conserved.

Artepillin C is a diprenylated phenylpropanoid with various pharmacological benefits for human health. Its natural occurrence is limited to a few Asteraceae plants, such as species, necessitating a stable supply through synthetic biology. In , the utilization of aromatic substrates within the cell was limited, resulting in very low production of artepillin C.

Article Synopsis
  • A novel co-culture system using a cyanobacterial strain (KC0110) was developed to support mammalian muscle cells in high-density cultures, addressing common issues like cell damage from waste accumulation.
  • The co-culture led to a significant reduction in harmful byproducts like ammonium and lactate while increasing beneficial compounds such as pyruvate and amino acids.
  • This research highlights a "symbiotic circular system" where metabolites are exchanged between the cyanobacteria and mammalian cells, improving cell viability and reducing damage in concentrated cultures.
