  • Adhesive property of bacteria and its relationship to microbial spoilage of shrimp

    Creator:
    Smith, John B.
    Abstract:
    Pacific shrimp (Pandalus jordani) was washed repeatedly and the eluted bacteria were enumerated and identified. Selected isolates were tested for their adhesive properties. Washing reduced the microbial load by 3.84 to 42.04%. The bacteria which most resisted wash-off were Staphylococcus and Pseudomonas spp. The easiest to wash off was Flavobacterium...
