Impacts of Chlorella vulgaris with or without co-existing bacteria on the removal of nitrogen, phosphorus and organic matter from wastewaters were studied by comparing the wastewater treatment effects between an algae-bacteria consortium and a stand-alone algae system. In the algae-bacteria system, C.vulgaris played a dominant role in the removal of nitrogen and phosphorus, while bacteria removed most of the organic matter from the wastewater. When treating unsterilized wastewater, bacteria were found to inhibit the growth of algae at >231 mg/L dissolved organic carbon (DOC). Using the algae-bacteria consortium resulted in the removal of 97% NH4(+), 98% phosphorus and 26% DOC at a total nitrogen (TN) level of 29-174 mg/L. The reaction rate constant (k) values in sterilized and unsterilized wastewaters were 2.17 and 1.92 mg NH4(+)-N/(mg algal cell ·d), respectively.
研究了小球藻（Chlorella vulgaris）与共存细菌对废水中氮、磷和有机物去除的影响，比较了藻菌共生体和独立藻类系统的废水处理效果。在藻菌系统中，小球藻在氮磷去除中起主导作用，而细菌则去除了废水中的大部分有机物。当处理未灭菌废水时，发现细菌在 >231 mg/L 溶解有机碳（DOC）时会抑制藻类生长。使用藻菌共生体可将总氮（TN）水平为 29-174 mg/L 的废水中 97%的 NH4(+)、98%的磷和 26%的 DOC 去除。在灭菌和未灭菌废水中的反应速率常数（k）值分别为 2.17 和 1.92 mg NH4(+)-N/（mg 藻细胞·d）。
