A bacteria-free culture system of Habrotrocha.sp.(Rotifera:Bdelloidea)built with disinfectants
应用消毒剂建立宿轮虫的无菌培养系

The rotifer Habrotrocha sp. is a common and useful microfauna in biological wastewater treatment. This study used disinfectants to set up a bacteria-free culture system of Habrotrocha sp. A new method was established to obtain the bacteria-free rotifer based on analyzing the hatching efficiency of Habrotrocha sp. and the bacteria density in rotifer culture medium containing the disinfectants sodium hypochlorite,formaldehyde or Preventol D7. The main idea was to gradually reduce the bacteria density in the r...
