摘要：

The efficiency in removal of ammoniacal-nitrogen and orthophosphate-phosphorus from continuous flow cultures was determined using two soil microalgae, Chlorella vulgaris and Scenedesmus bijugatus, entrapped in 4-mm calcium-alginate beads. Beads each stocked with 10(8) cells of both cultures removed 71 to 79% more nitrogen and 52 to 82% more phosphorus within 6 h compared to those with a stocking density of 10(5) cells bead-1. C. vulgaris was more efficient in the removal of both nutrients than S. bijugatus. Exponentially growing cells of the two isolates effected greater uptake of phosphorus, whereas the age of the cultures was found to have no direct impact on the removal of nitrogen.
