Isolation and characterization of enterocin EJ97, a bacteriocin produced by Enterococcus faecalis EJ97.

abstract：:Penicillium marneffei is a dimorphic fungus that intracellularly infects the reticuloendothelial system of humans and bamboo rats. Endemic in Southeast Asia, it infects 10% of AIDS patients in this region. The absence of a sexual stage and the highly infectious nature of the mould-phase conidia have impaired studies o...
