| Abstract: | Objective] The study was to explore whether antimicrobial activity of the antimicrobial peptides extracted from immunized Tenebrio molitor vary with different pathogens as inducers.Method] By inducing hungry T.molitor larvaes to generate immune response via feeding with bacteria and with fungi or actinomycete after pricking,the antimicrobial peptide extract was obtained by grinding and centrifuging the cultures.Its antimicrobial activity against 26 pathogens was measured by bacteriostatic ring,and evaluat... |
