✦ Synopsis

Anabaena doliolum and Chlorellu vulgaris immobilized on chitosan were more efficient at removing NO,; NO,; POd3-and Cr,O,*-from wastewaters than cells immobilized on agar, alginate, carrageenan or even free cells. Carrageenan-immobilized cells, however, were better at removing NH,+ and Ni". The P0,3--uptake capacity was significantly increased in cells starved of POa3-for 24 h. Agar-immobilized cells, though having good metal and nutrient uptake efficiency, had only a slow growth rate. Chitosan is recommended as an algal support for wastewater detoxification.
