Persistence and occurrences of bacteria on wastewater in selected treatment plant of UiTM Pahang branch, Jengka Campus / Zulhafizal Othman ... [et al.]

Coliform bacteria are present in the environment and feces of all warm-blooded animals and
humans. Fecal coliform bacteria are a subgroup of total coliform bacteria. They exist in the
intestines and feces of people and animals. E. coli is a subgroup of the fecal coliform group.
Human or animal feces infected with E. coli sometimes get into lakes, pools, and water
supplies. This research is conducted to identify the occurrence of the bacteria in influent and
effluent of wastewater discharged from selected treatment plant in Universiti Teknologi
MARA (UiTM) Pahang. The samples were taken and preserved before further analysis. The
method used in this experiment is presumptive total coliform test using m-Endo broth (MF).
MF Method is a fast and simple way to estimate bacterial populations by passing an
appropriate sample volume through a membrane filter (0.45 microns) small enough to retain
the bacteria present. Several samples were tested and the result showed that the bacteria (total
coliform bacteria) are persistence in the sample and further discussion have been done by
referring to the Water Quality Index from Department of Environment, Malaysia
