| Summary: | Forty six bacterial strains were isolated from nine different sources in four treatment plants
namely Indah Water Konsortium (IWK) sewage treatment plant, International Islamic University
Malaysia (IIUM) treatment plant-1,-2 and –3 to evaluate the bioconversion process in terms of
efficient biodegradation and bioseparation. The bacterial strains isolated were found to be 52.2% (24
isolates) and 47.8% (22 isolates) in the IWK and IIUM treatment plants respectively. The results
showed that the higher microbial population (9-10x104 cfu mL�1) was observed in the secondary
clarifier of IWK treatment plant. Only the gram-staining identification was done in the strains isolated
from IWK treatment plant not to be determined from IIUM. Among the isolates from IWK, 10 isolates
of gram-positive bacillus (GPB) and gram-positive cocci (GPC), 10 isolates of gram-negative bacillus
(GNB) and rest were both or undetermined. Gram-negative cocci (GNC) were not found in the isolates
from IWK. |
