However, less than 2% of red mud produced is currently utilized. Red mud contains a number of residual scarce metals including rare earth elements, some at a considerable concentration, so synchronous cultures of the red microalga Galdieria sulphuraria were tested for their ability to grow in red mud-containing medium and accumulate these rare earth elements from the mud. Red mud was added to the growth medium as an acid extract (in 10% v/v HNO3). Pigment content and photosynthetic performance are indicators of physiological condition and stress levels in microalgae. Growth of the treated culture was suppressed compared to an untreated control and the content of chlorophyll a and phycocyanin decreased while carotenoids increased substantially. Photosynthetic performance, determined as Fv/Fm, was almost unaffected by the red mud treatment. The concentration of individual rare earth elements in the red mud extract and the biomass, was determined using ICP-MS. The most accumulated rare earth elements were Ce, Nd, La, and Y (26, 15, 11 and 11 µg g−1 DM, respectively). G. sulphuraria was also cultivated under different trophic regimes, auto- and mixotrophically, with the addition of red mud extract. Growth of all cultures were comparable. The concentration of total accumulated rare earth elements was surprisingly high in mixotrophic G. sulphuraria (109 µg g−1 DM) but was tenfold lower in the autotrophic culture.
