Ammonia toxicity in water bodies is a global problem. Different approaches have been
adopted to get the ammonia concentration in water back to permitted level (0.5 mg L− 1 for …

Presence of higher concentration of ammonia (> 0.5 mg/L) as well as nitrite (> 0.2 mg/L) in
aquaculture environment create difficulties for fish survival. The existing methods for removal …

Remediation of aquaculture water using microorganisms like Bacillus species is a
burgeoning trend for the sustainable development of aquaculture industries. In this work, a …

Innovative removal of toxic nitrite and ammonia is one of the key approaches for efficient
aquaculture biotechnology. This study suggests a fast removal technique of high-levels of …

The presence of high concentrations of ammonia, nitrite, and nitrate is a big challenge for
the aquaculture industry to sustain fishery production, hence need to be treated in an …

Extensive growth of industries leads to uncontrolled ammonia releases to environment. This
can result in significant degradation of the aquatic ecology as well as significant health …

A self-design bioreactor system employing a fixed bed operation process with immobilized
Bacillus subtilis AYC beads for NH4+-N removal from slightly polluted water was proposed …

Drinking water treatment through biological process is commonly applied in developed
countries, but not yet in developing countries such as Malaysia. The non-existence of …

A bench-scale fluidised bed bioreactor was used to treat aquaculture effluent intended for
recycling. The reactor was loaded with ammonia-nitrogen (NH4-N) from 0.025 to 5.675 gm …

An efficient ammonia nitrogen degrading bacterial strain was isolated from a fish and shrimp
pond and identified as Bacillus subtilis (Ab03). Firstly, the strain was continuously …
