Morphology and Structure

Trichomes are pale blue-green and form a geometrically regular spiral. During biomass cultivation, trichomes form characteristic dirty dark-green clusters.

Cultivation

• Nutrient Medium: Zarrouk’s medium (liquid and agarized)
• Temperature: 27–30 °C
• Light Intensity: 50–150 µmol photons/m²/s
• Photoperiod: 16:8 h (light/dark)
• pH: 8.0–10.0.

Physiological Characteristics

Mesophile, autotroph.

Long-term Preservation Conditions

Maintained on liquid and 1.5–2.0% agarized Zarrouk’s medium. Storage temperature 10–12 °C, light intensity 10–20 µmol photons/m²/s, photoperiod 12:12 h (light/dark). Subculturing is carried out as needed, but at least once every 2–4 months.

Field of Application

In fundamental research and biotechnology.
