The invention discloses
bacteria capable of synchronously removing organic substances and
ammonia nitrogen in water of a slightly polluted
water source under low-temperature and aerobic conditions and a screening and domesticating method, which relate to
bacteria and a screening and domesticating method and solve the problem that the prior
bacteria are unsuitable for treating the slightly polluted
water source as well as
low temperature treatment. The bacteria SRA10 of the invention are
acinetobacter lwoffi which belong to
acinetobacter baumannii and are preserved in China General
Microbiological Culture Collection Center on January 19th, 2009, with a preservation number of CGMCC No.2889. The
screening method comprises the following steps: I, separating and purifying; II, preparing bacterial solution; III, screening and cultivating a bacterial solution; IV, screening and cultivating a bacterial solution with a live strain; V, repeating the step IV for 1 to 2 times, and stepwise domesticating the live strain; and VI, taking a bacterial solution of the domesticated strain, and rescreening the bacterial solution to obtain the bacteria. The bacteria obtained by screening and domesticating can process water of the slightly polluted
water source under a condition of a low temperature of 2 to 10 DEG C.
