NEUTRALIZATION OF TOXINS IN AQUA CULTURE USING PROBIOTICS

Bioremediation is a waste management method where we can employ different types of microorganism’s to nullify the effect of pollutants from a contaminated site. In the current study the authors have carried out a three months study to find out how different bacterial strains of Bacillus licheniformis, B. substilis and   pseudomonas species can be used to assess the water quality in terms of parameters like pH, dissolved   oxygen, free ammonia, total ammonia and nitrite and turbidity from the discharge of common ponds. The study was carried to evaluate the physico-chemical parameters of the catla and selavathi culture ponds by applying probiotics. During the process of investigation one pond was treated with probiotics having Bacillus licheniformis, B. subtilis and Pseudomonas species and to study the efficacy of results the pond to which probiotics were not added was kept as control. The current study is aimed not only to focus on the changes in water quality but also biochemical characterization of bacterial species and to understand what concentration of the bacterial species is more effective in bioremediation of probiotic treated ponds and ponds not treated with probiotics.
