The Bignell Laboratory of Molecular Microbiology and Plant-Microbe Interactions
Department of Biology
Memorial University of Newfoundland
Research in the Bignell Lab focuses on the following:
(1) Characterization of virulence-associated secondary metabolites produced by the common scab pathogen Streptomyces scabies
(2) Isolation of scab-causing Streptomyces spp. from Newfoundland and characterization of the associated secondary metabolites produced by these species.
