Results After screening, 59 subtracted library clones were isolated which were specific for strain VIB72, and the DNA sequences of these clones were determined. Seventeen fragments showed high homology to the genes of known functions in other bacteria. This includes soluble lytic murein transglycosylase, mobilization protein, transposase (IS66), resistance-related protein (metallo-beta-lactamase and acetyltransferase family), toxin protein (DT-201 and alveicin A immunity protein), ATP-dependent endonuclease of OLD family like protein, SocE and GTP-binding protein HflX (high frequency of lysogenization).

In chapter four, molecular imprinting polymers against amino acid derivatives utilizing 2-VP+AM as combined functional monomer and trimethylolpropane trimethacrylate as tribasic cross-linker were prepared and result was compared with those with the same amino acid derivative as the imprinted molecules utilizing ethyleneglycol dimethacrylate as dibasic cross-linker. It was found that cross-link intensity of the molecular imprinting polymer is higher when TRIM was utilized and baseline separation for the imprinted molecule could be achieved. When TRIM was utilized as cross-linker more molecule is imprinted during the polymerization.
