Implication

Study evaluates growth and metabolite responses in Aphanothece species, suggesting tailored cultivation enhances yield for biotechnological applications.

Key Points

This research aims to assess how temperature and light intensity affect the growth and metabolite profiles of two Aphanothece species.
Utilized a 3x2 full factorial design to explore the effects of three temperatures and three light intensities.
Measured growth, pigment composition, and lipid profiles of A. microscopica and A. stagnina.
Conducted fatty acid analysis to evaluate differences in lipid content across conditions.
A. microscopica accumulates chlorophyll a and diverse carotenoids under high temperature and low light.
A. stagnina shows increased pigment productivity at high temperature and light, enriching zeaxanthin and β-carotene.
Both strains show increased lipid content under low temperature and moderate light, with different fatty acid profiles observed.
