A glimpse into darkness: Diversity of culturable cyanobacteria, green algae and fungi from subaerial cave biofilms. [PDF]

J Phycol
Abstract Caves and hypogean environments provide stable microclimates characterized by uniform temperatures, constant humidity, and low light levels. In such sites, extremely low light irradiance can support the growth of subaerial biofilms (SABs) dominated by unique photosynthetic communities of cyanobacteria accompanied by chlorophytes, heterotrophic

Lipid extraction from Aphanothece sp. using ultrasounds

Journal of Physics: Conference Series, 2020
Abstract The unprecedented reduction in the availability of fossil fuels requires the research community to find safe, clean, renewable and sustainable energy sources. One promising source is microalgae biofuel, which can reduce environmental problems and energy crises due to its closed carbon cycle.

Boundaries of photosynthesis: adaptations of carbon fixation in extreme environments. [PDF]

FEBS Open Bio
Photosynthesis faces challenges from environmental extremes of temperature, pH, and salinity, limiting gas diffusion, modifying membrane fluidity, and destabilizing photochemical and biochemical reactions. Photosynthetic organisms have evolved unique adaptations overcoming these stresses and maintaining their photosynthetic activity.
