为探究枯草芽孢杆菌(Bacillus subtilis)培育生物絮团对浮游生物的影响,以枯草芽孢杆菌作为试验菌种,以养殖池塘水为试验用水,在有机玻璃水族箱(100 cm ×60 cm ×50 cm)中进行为期40 d的生物絮团培育试验。试验以添加葡萄糖为处理组I,同时添加枯草芽孢杆菌和葡萄糖为处理II组,仅添加枯草芽孢杆菌为处理III组,对照组不添加任何物质。试验过程中每5 d对各组水体取样,对形成的絮团物质进行显微观察,同时对各组水体中浮游生物进行定性和定量分析。结果表明,本试验条件下,处理I组和处理II组在第15天左右形成成熟生物絮团,生物絮团形成前期(试验开始至第15天),生物絮团组(处理I组和处理II组)水体中浮...

Biofloc is an advanced technology in aquaculture and can effectively reduce excessive nitrogen in water, improve the immunity of aquatic animals and provide natural food for some fish species and shrimp. In this study, a biological flocculation test was conducted to evaluate the effects of biofloc on the species number and quantity of plankton in pond water, aiming to provide a reference for treatment of pond culture wastewater and to extend exist-ing research on biofloc technology. From May to August, 2015, a biological flocculation test was c...
