High cadmium tolerance in Stichoccocus-like microalgae (Tetratostichoccocus sp. P1) from Malaysia

Cadmium (Cd) is a common industrial pollutant that has become a global issue due to its toxicity to living creatures, particularly aquatic organisms. Algal-based treatment offers cost-effective and environmentally friendly solutions for heavy metal removal. In this work, we studied the acid-tolerant...

P1 strain cultivated in high-level Cd concentrations at pH 3.0. Tetratostichoccocus sp. P1 grew best in 20 μM and could survive in a concentration up to 100 M, according to the specific growth rate (μ = 0.36 ± 0.05 d−1) and the chlorophyll content (28.24 μg mL−1).
