Bathycoccus prasinos

Bathycoccus prasinos is a species of marine green algae belonging to the class Mamiellophyceae. It is recognized as one of the smallest eukaryotic organisms found in the world's oceans, typically measuring less than two micrometers, which classifies it as an essential component of the global picoplankton community.

The organism is distributed globally across various marine environments, ranging from tropical to polar waters. It thrives primarily in the euphotic zone, where it plays a critical role as a primary producer, capturing solar energy and contributing significantly to the marine food web through carbon fixation processes.

Botanically, Bathycoccus prasinos is distinguished by its unique cell morphology, featuring a cell surface covered with distinct organic scales. Its genome is highly compact and optimized for survival in nutrient-limited oligotrophic open ocean waters, allowing it to compete effectively with other phytoplankton species.

In terms of industrial application, this species is of growing interest in marine biotechnology and aquaculture. It is currently being studied for its potential in large-scale biomass production, serving as a high-quality feed source for juvenile aquaculture species, as well as a raw material for extracting lipids, proteins, and pigments for commercial use.

Cultivation protocols for Bathycoccus prasinos focus on simulating stable marine conditions within photobioreactors to maximize yield. Key factors for successful production include:

• Precise temperature management to maintain optimal metabolic rates.
• Utilization of specialized seawater-based culture media supplemented with nitrogen and phosphorus.
• Controlled lighting cycles to replicate the natural photoperiod and intensity.
• Rigorous pH monitoring to ensure the stability of the aquatic environment.
