| dc.description.abstract | An investigation of natural attenuation as well as application of bioaugmentation
techniques in reduction of heavy metals in contaminated sediment is studied. Five elements were
chosen for this study namely zinc (Zn), lead (Pb), ferum (Fe), cadmium (Cd) and copper (Cu).
Both techniques have been applied to sterilized and non-sterilized sediments with different
dosage of bacteria inoculum (1 mL and 2 mL of 108 cell/mL microbes). The percentages of
concentration reduction in sediment in the relative order as follow: Cd>Pb>Zn>Cu>Fe in natural
attenuation. For augmentation technique, Cd reduction was the highest at range between 76.86-
92.37% while Fe was the lowest at range between 4.19-10.06% for addition of 1 mL and 2 mL
of bacteria inoculate in both sterilized and non-sterilized sediments. | en_US |
