有机氮化合物对海洋浮游植物生长的影响

EFFect of Organic Nitrogen on the Growth of Marine Phytoplanton

研究了苯丙氨酸、半胱氨酸、尿素以及生活污水中的溶解有机氮化合物对骨条藻等海洋浮游植物生长速率的影响．结果表明这些有机氮可作为藻类生长的一种氮源，能被藻类间接或直接地吸收利用，对藻类的生长起到维持或促进作用。

The effect of phenylalanine, cysteine, urea and organic nitrogen compoundsin sewage water on the growth rate of some marine phytoplankton is studied. The results indicatethat these organic nitrogen compounds can be taken by phytoplanktons as nitrogen sources to sus-tain and stimulate their growth.
