Parachlorella Kessleri: A Microalga with Incredible Powers<\/h2>\n\n\n\n

Recently highlighted in an episode of the podcast “Avec sciences” podcast on France Culture<\/strong><\/a> the microalga Parachlorella Kessleri<\/strong>, a “cousin” of chlorella<\/a><\/strong> is in the news for its unique ability to absorb heavy metals. This discovery confirms the essential role played by microalgae<\/a> in protecting our environment and human health.<\/p>\n\n\n\n

What is Parachlorella Kessleri?<\/h3>\n\n\n\n

Parachlorella Kessleri is a green microalga belonging to the Chlorellaceae family. It stands out for its ability to capture toxic heavy metals<\/strong>, such as lead, mercury and cadmium, from polluted environments. Its potential is promising in the fight against soil, water and ecosystem contamination.<\/p>\n\n\n\n

Schematic representation of the zinc remediation mechanism using Parachlorella kessleri microalgae. In the presence of ammonium nitrogen, the cell does not capture zinc. In the presence of nitrate nitrogen, the cell secretes extracellular polymeric substances (EPS) that interact strongly with zinc – \u00a9 TBI – Radio France<\/figcaption><\/figure><\/div>\n\n\n\n

Microalgae, like chlorella, use a natural bio-absorption<\/strong> process to capture and store heavy metals. This mechanism is based on the structure of their cell walls, which act as a magnet for these harmful elements.<\/p>\n\n\n\n
