Bioprocess development for biosorption of toxic heavy metals from industrial effluents
1997
Mohd Razman Salim | Zaharah Ibrahim | Abu Bakar baba (Universiti Technologi Malaysia, Skudai Johor Darul Ta'zim (Malaysia). Dept. of Environmental Engineering)
Pollution of the environment by toxic metals arises as a result of human activities such as industrial, agricultural, mine-drainage and sewage disposal. Once in the environment, the metal undergo several forms of transformations. The removal of toxic metal is of great significance from the environmental and industrial point of view. The increased in sound environment and stringent legal requirements has led to the need for cost effective treatment technology for metal pollution control. Biological treatment processes using microbial biomass are known capable of treating industrial waste successfully. The initial aim of the project was to screen a number of metal-tolerant organisms and develop microbial strain capable of detoxification, biosorption and recovery of heavy metals. Due to limited knowledge based studies on several industrial wastes are necessary to determine the potential strains as well as the viable technique to be used in recovery/removal of heavy metals

Isolation, identification and bioremediation potential of oil-degrading bacteria from Manila Bay and Pasig River [Philippines]
1997
Dela Cruz, J. | Halos, P.M.
Oil-degrading bacteria were isolated from waters and sediments of the Manila Bay and Pasig River [Philippines]. Five types of bacteria were isolated from Manila Bay and four from Pasig River. The identified crude oil degrading species are Vibrio sp., Alcaligenes sp., Flavobacterium indologenes and Acinetobacter sp. from Manila Bay, and Pseudomonas aeruginosa, Bacillus sp., Micrococcus sp. and Pseudomonas putida from Pasig River. These isolates were identified through morphological and physiological characterization. The bioremediation potential for each of the isolates was assessed. The percentages oil conversion for the bacterial isolates ranged from 2.99 percent - 53.44 percent in one week's time. Alcaligenes sp. exhibited the highest biodegradation potential for all isolates. Statistical analysis revealed that the mean percentages diesel oil conversion by the isolates were significantly higher than their mean percentages crude oil conversion. Pure and mixed cultures did not give significant differences in their mean percentages crude oil conversion
