Only within the past decade has the potential of metal biosorption by biomass materials been well established. Waste crab shell and certain metal-binding algae are found in large quantities in the sea. These biomass serve as a basis for newly developed metal biosorption processes foreseen particularly as a very competitive means for the detoxification of metal-bearing industrial effluents. The assessment of the metal-binding capacity of some new biosorbents is discussed. Biosorption isotherm curves, derived from equilibrium batch sorption experiments and dynamic continuous-flow sorption and...

Biodegradation of Naphthalene, Phenanthrene and Anthracene by Micrococcus sp., Rhodococcus sp. and Pseudomonas putida were studied. The effects of pH, glucose concentration and inoculum concentration were investigated. Maximum degradation and high microbial growth were observed at pH (7), glucose concentration (500 ppm) and inoculum concentration (3%). To investigate the maximum tolerance potential for the selected bacteria, naphthalene (500-5000 ppm), Phenanthrene and Anthracene (50-500 ppm) were used in the presence of non-ionic surfactants. The examined surfactants (Triton X-100 and...
