“海立”牌生态洗涤剂对滇池藻类的影响

The effects of "Haili" detergent on the growth of Algae from Dianchi Lake

"海立"生态洗涤剂是陕西海立生态环保科技公司生产的纯天然物洗涤剂.将不同体积量的该洗涤剂按不同体积比加入到采自滇池倒石头、大坝、西华街、晖湾、海埂5个样点的200 mL水样中,使成不同浓度,室温培养.结果发现水体中洗涤剂与水样的体积比为10-4时藻类生长受到抑制;体积比大于或等于10-3时藻类被完全杀灭.用含不同浓度该洗涤剂的培养液培养铜绿微囊藻(Microcystis aeruginosa)时,发现藻体生长受到明显抑制;洗涤剂能抑制藻类的原因可能与洗涤剂中盐单胞菌(Halomonassp.)的存在有关.

The 'Haili' detergent,made from natural sources,is manufactured by Haili Eco Environmental Protection Technology Co.,Shanxi Province.The detergent was mixed at different ratios with five water samples picked from Daoshitou,Daba,Xihua Street,Huiwan Bay,and Haigeng of Dianchi Lake,respectively,and then incubated at room temperature.The growth of algae in the water samples was inhibited when the concentration of the detergent was 10-4 V/V.The algae were completely killed when the concentration of the detergent was equal to 10-4 V/V or higher.The growth of Microcystis aeruginosa was inhibited when cultivated in media that contained different concentrations of the detergent.The inhibitory effect of the detergent on the growth of algae might be related to Halomonas sp.existed in the detergent.
