  1. Myceloid cell formation in Arthrobacter globiformis during osmotic stress

    Perera, Ganegodage Shyama

    … was found to form myceloids when subjected to osmotic stress. Addition of known osmoprotective compounds did not relieve this effect. Since myceloid formation may result from altered penicillin-binding proteins (PBPs), PBP profiles of stressed and unstressed A. globiformis were studied. Eight …
