Preventing contamination in algae cultures involves maintaining sterile conditions, monitoring water quality, and controlling environmental factors that favor unwanted organisms. Starting with clean equipment, sterilized water, and verified pure algae strains reduces the risk of introducing bacteria, fungi, or competing algae species. Regular cleaning of tanks, tubing, and filtration systems helps prevent biofilm buildup, which can harbor contaminants.
Maintaining optimal nutrient levels, light conditions, and water flow promotes healthy algae growth, leaving less opportunity for invasive species to thrive. Careful monitoring allows early detection of contaminants, so adjustments can be made before they spread. In some cases, antibiotics, antifungal agents, or specific filtration methods can be used to control outbreaks, though these approaches are used cautiously to avoid harming the algae or affecting product quality.
