Key Points

This research aims to investigate the physiological and mechanical interactions in a microalgae-yeast co-culture.
Assessed physiological performance through biomass and lipid production measurements.
Utilized atomic force microscopy (AFM) and FluidFM techniques for nanomechanical analysis of cell interactions.
Evaluated photosynthesis and extracellular polymeric substances (EPS) production in co-culture.
Co-culture increased microalgal lipid and biomass production by 4-fold due to effective gas exchange.
Co-culture enhanced photosynthesis and EPS production in microalgae.
AFM indicated a decrease in yeast cell wall stiffness under co-culture, enhancing microalgal-yeast interactions.

Implication

Shows enhanced lipid and biomass production in microalgae via co-culture, suggesting improved synergy with yeast.

Abstract

• Co-culture boosts microalgal lipid and biomass production 4-fold via gas exchange. • Co-culture triggered microalgal photosynthesis shift, lipid, and EPS production. • AFM revealed reduced yeast cell wall stiffness under co-culture conditions. • FluidFM showed stronger microalgae-yeast interactions due to enhanced EPS production.
