Methods for preventing or alleviating the accumulation of nitrite in aqueous environments are also provided, using the nitrite-oxidizing bacteria of the present invention. Methods for detecting the bacteria of the present invention are also provided. Compositions comprising the nitrite-oxidizing bacteria of the present invention and, inter alia, ammonia-oxidizing bacteria, are also provided.

Claims (4)

1. A biologically pure culture of a bacterial strain that oxidizes nitrite to nitrate, wherein the 16S rDNA of the bacterial strain has a nucleotide sequence comprising SEQ ID NO:1.

2. A composition, comprising a concentrated isolated bacterial strain that oxidizes nitrite to nitrate wherein the 16S rDNA of the bacterial strain has a nucleotide sequence comprising SEQ ID NO:1.

3. The composition of claim 2 , further comprising a microorganism selected from the group consisting of ammonia-oxidizing organisms, nitrite-oxidizing microorganisms, nitrate-reducing microorganisms, heterotrophic microorganisms and combinations thereof.

4. A composition comprising nitrite-oxidizing bacteria and ammonia-oxidizing bacteria, present in an approximately 1:3 ratio, wherein the nitrite-oxidizing bacteria comprises an isolated bacterial strain having 16S rDNA including a nucleotide sequence identical to SEQ ID NO:1.
