Pedinomonas minor

Pedinomonas minor is a genus of green flagellated microalgae belonging to the family Pedinomonadaceae. As a single-celled organism, it is widely studied in phycology due to its primitive evolutionary status and efficient photosynthetic machinery.

The cultivation of this species requires precise control of environmental factors, primarily light intensity and spectral quality. High-efficiency LED systems are frequently used to provide the necessary photosynthetically active radiation to drive biomass production.

Temperature management is crucial, with growth typically occurring between 18°C and 25°C. Stability in thermal conditions prevents physiological stress, which could otherwise alter the lipid or protein profile of the algal cells, affecting their intended industrial use.

Nutrient supply protocols must be strictly followed, ensuring a proper ratio of nitrates, phosphates, and trace metal ions. The availability of carbon sources, often supplied via bubbling atmospheric air or enriched CO2, is a limiting factor for high-density growth in closed bioreactors.

Water quality parameters, including pH stability and the absence of inhibitory contaminants, determine the longevity of the culture. Maintaining a sterile or semi-sterile environment is essential to prevent contamination by competing protozoa or invasive bacterial strains that could crash the algal population.
