Synchrotron radiation reveals mechanism of acidophilic microalga PM01 tolerating high-concentration manganese
Researchers have used synchrotron radiation techniques to reveal the key mechanism by which an acidophilic green microalga survives in high-concentration manganese environments. The research subject is the acidophilic alga C. acidophila PM01, originally isolated from an acid mine drainage pond, which can survive at manganese concentrations up to 50 mM (approximately 2.75 g/L), making it one of the most manganese-tolerant microalgae reported to date. Manganese is a nutrient element required by organisms, but during processes such as mining, ore processing, and electrolytic manganese production, high concentrations of manganese can enter water bodies and cause pollution. In particular, manganese removal is difficult in acidic waters. Some microorganisms can adapt to such extreme environments, but their tolerance mechanisms still require fine analytical tools to elucidate...
