中文摘要：在温度(28±1)℃、盐度28下,将产乳酸芽孢杆菌制剂添加到养殖10尾凡纳滨对虾、容水200L的0.3m^3室内玻璃钢桶中,使芽孢杆菌终密度为10~4、10~5、10~6 cfu/mL,以无益生菌添加组为对照组。定期测定养殖水体中的氨氮、亚硝酸盐氮和硝酸盐氮的含量,以及总异养菌、弧菌和芽孢杆菌的数量。试验结果显示,试验结束时,添加芽孢杆菌各试验组养殖水体中氨氮、亚硝酸盐氮和弧菌的含量显著低于对照组(P<0.05);添加高密度芽孢杆菌试验组(10~6 cfu/mL)养殖水体中总异养菌的数量显著高于对照组(P<0.05);添加芽孢杆菌对养殖水体中的硝酸盐氮含量未产生显著的影响(P>0.05);添加芽孢杆菌后养殖水体中的芽孢杆菌数量在第4d后会出现下降趋势。试验还发现,在养殖后期初次投入芽孢杆菌时会引起养殖水体中氨氮含量的短期升高。试验结果表明,芽孢杆菌能改善对虾养殖水体水质,可作为益生菌用于对虾养殖中。

外文摘要：Bacillus strains producing lactic acid as probiotics were added into 0.3 m^3 glass fiber reinforced tanks stocked with 10 individuals of Pacific white leg shrimp Litopenaeus vannamei at final concentration of 0（control group）,10~4,10~5 and 10~6 cfu/mL at water temperature of（28±1）℃ and a salinity of 28 for 7 d to evaluate the effects of the Bacillusstrains on water quality（concentrations of ammonia nitrogen,nitrite nitrogen and nitrate nitrogen,and the number of total heterotrophic bacteria,Vibrio and Bacillus）in shrimp culture.The results showed that supplementation of Bacillus led to significant decline of concentrations of ammonia nitrogen and nitrite nitrogen,and number of Vibrioin the water compared with those in the control group（p〈0.05）.There was significantly higher number of total heterotrophic bacteria in the water supplemented with high concentration of Bacillus group（10~6 cfu/mL）than that in the control group（p〈0.05）,without significant difference in concentration of nitrate nitrogen（p〈0.05）.The reduction in number of Bacillus was observed 4 days after addition of Bacillus,and short period of increase in the concentration of ammonia nitrogen in water was found at supplementation of the Bacillusin the later rearing period.The findings indicated that Bacillusimproved the water quality,and had potential application in shrimp rearing.
