THE SANITISING EFFICIENCY OF DIFFERENT DISINFECTANTS USED IN THE FISH INDUSTRY
This study examines the bactericidal efficiency of common disinfectants using the modified surface testing method against adherent cells on stainless steel surface (type 304, 2B). Mixed culture of Pseudomonas putida, Serratia liquefaciens and Shewanella putrefaciens isolated from shrimp and fish pro...
