ANTIBACTERIAL ACTIVITY OF SOME SYNTHETIC CHEMICALS

for the growth of one gram-positive (Staphylococcus aureus)
and two gram-negative (Escherichia coli and Klebsiella pneu-
moniae) bacterial strains. The culture that shows no growth in
the presence of the lowest concentration of the complex repre-
sents the MIC of the complex against those particular bacteria.
The findings are given in Table 3.
From the data, it was observed that the antibacterial activity
of these compounds showed significant increase on coordina-
tion. This enhancement in the antibacterial activity may be due
to the possession of an additional azomethine bond. It has been

of the metal ion mainly because of the partial sharing of its
positive charge with the donor groups within the chelate ring
system. This process, in turn, increases the lipophilic nature
