Translation seminar the same NH4
þ - N load (about 100 mg / L) (6). Furthermore for, Bacillus
sp. LY (16) and Pseudomonas Alcaligenes. AS-1 (17), the
ammonium removal rates were just 0.43 mg-N / L / h and 1.15 mg-N /
L / h respectively which were significantly,,, Lower than that of the
present study. TN was removed by 87.8% from the medium in, 22 h
.Indicating the heterotrophic nitrogen removal capability by Acinetobacter
sp. Y1. A few intermediates were observed in. The nitrification
process possibly due, to the fast conversion to the
downstream products such as nitrogen. However accumulation,, Of
nitrite has been reported during ammonium oxidation by Bacillus
methylotrophicus L7 (18), Alcaligenes faecalis C16 (19). And Marinobacter
sp.F6 (20), while production of both nitrite and nitrate
were found for Rhodococcus sp. CPZ24 (21). The concentration of TN
was. Slightly higher than that of NH4
þ - N after 12 h. The nitrogen
released from bacteria decay might be responsible for this. Phenomenon
(7, the 22). Similar results have been found for Pseudomonas
stutzeri YZN-001 (23) and Acinetobacter sp. Y16 (22).
