Lactic streptococci: growth characteristics and plasmid profiles of drug- and bacteriophage-insensitive mutants

Creator:

Wulf, John J.

Abstract:

Fast acid-producing streptomycin-resistant mutants for several strains of lactic streptococci currently used in commercial Cheddar cheese manufacture were isolated. Their isolation involved use of a recently developed differential plating medium that allows identification of fast acid-producing colonies. Both parents and mutants were characterized with regard to growth, acid production, proteolytic...
