Study of temperatures and concentrations on fast biodegradation of toxic BPA by Pseudomonas Aeruginosa NT. 22 isolated from Malaysian pond / Mohd Afiq Mohd Rafidi

There are more attentions have been focused on environmentally friendly ways on how to solve some of arises problem due to the globally increase in water pollution and aquatic imbalance. There is also incremental in public awareness regarding on this problem. One of the techniques is the use of microorganisms and their aggregates and the biodegradation methods for the treatment of phenol contaminated wastewater are more effective and less costly. Phenolic compound regarding on the pollution, it is one hazardous pollutant that is toxically relative at low concentration which the accumulation of the phenol creates toxicity at both flora and fauna. Bisphenol A is one of the most common toxic environmental pollutants that originate mainly from industrial processes and there is need to decontaminate. The objectives of this work are to study the effect of two variables which are the temperature (30°C, 35°C, 40°C, 45°C, 50°C, 55°C and 60°C) and the concentrations (100ppm, 150ppm, 200ppm, 250ppm, 300ppm, 350ppm and 400ppm) as to identify the significant effects and interactions in the batch studies. This is because it was found that temperature and concentration significantly affecting the degrading potential of Pseudomonas aeruginosa on the toxic BPA. The optimum conditions of the variables for the growth of Pseudomonas aeruginosa and for maximum biodegradation of bisphenol A are at the temperature of 30°C and with the concentration of 100ppm based from the result obtained. These results are useful as to understand the physiological and biochemical properties of Pseudomonas aeruginosa before its optimum use in environmental application and these datas will assist in choosing the right bisphenol A degrader for a changeable environment.
