    Growth of an oil oxidizing bacterium (nap C) on phenanthrene
    (Terengganu: Universiti Putra Malaysia Terengganu, 2000) Ong Pei Thing
    Nap C, an oil-oxidizing bacterium was isolated from sediment of Port Dickson coastal water. It is a gram-negative bacterium and form spore under unfavourable conditions. The optimum environmental conditions for the growth of Nap C on phenanthrene were pH 8, salinity 30 g/1 and temperature 30 oc. Besides, 40 mg/1 of yeast extract was required for Nap C to grow on phenanthrene in the synthetic medium. Growth supported by addition of 40 mg/1 yeast extract was insignificant (P>0.05).

    The role of exogenous antioxidants L-ascorbic acid and a-tocophpherol on the depuration of polyclorinated biphenyl 126 (PCB1260) in the marine mussel, Perna viridis
    (Terengganu: Universiti Malaysia Terengganu, 2014) Ong Pei Thing
    Retention of persistent organic pollutants (POPs) in organisms is one of the key concerns in environmental safety. The retention time of POPs in organisms is regulated by bioaccumulation and depuration. Depuration of POPs from an organism depends on the homeostatic balance of oxidant and antioxidant at its cellular level.
