Abstract :
A 4 days study was conducted to determine the
effects of Different concentration of
bioaugmentor bacterial strain Bacillus
licheniformisi, B. subtilis, B. polymyxa, B.
laterosporus and B. circulans (Protexin
Aquatech, UK) on adjustment of parameters of
water quality as TAN, NO2-N, NO3-N and
turbidity from the effluent of Common Carp
ponds. Effects of time and concentration were
studied as a completely randomized split-plot
design. Time and concentration and their
interaction had a significant difference (P < 0.05)
on changes of total ammonium nitrogen, nitrate
nitrogen, nitrite nitrogen and turbidity. The total
counts of bacteria recorded in the water of
bioremedated tanks were also lower than that in
the control tank
