  The Milk Production Line provides a variety of micro-environments in which multiple microorganisms can multiply. We sample cracks and joints, and bacteria can survive and form biofilms due to inadequate sterilization procedures. The sampling locations are storage tanks, refrigerated tanks, pasteurizers, and tank-transfer pump connections. The culturable bacteria isolated after the hygienic procedure are mainly Pseudomonas. Serratia, Staphylococcus and Stenotrophomonas maltophilia. We analyzed several phenotypic characteristics, such as the ability to secrete enzymes and iron carriers, and the ability of strains to form biofilms, which may contribute to their survival in a mixed environment. Pseudomonas. The isolate was found to produce high levels of protease or lecithinase. Interestingly, protease yield is inversely proportional to iron carrier production. In addition, all Serratia. The isolate is a strong biofilm former and a spoiled enzyme generator. The identified organisms are not only contaminants but also producers of proteins, potentially reducing the quality and shelf life of the milk. In addition, we found quite a few Serratia and Pseudomonas. Compounds isolated from pasteurizers are capable of secreting compounds having antibacterial properties.
  Introduction
  One of the most challenging tasks in any industrial food processing line is to maintain hygienic conditions because the high availability of nutrients and oxygen is beneficial to the growth of microorganisms. In addition, the actual setup of the line – including cracks, valves and gaskets – makes it more difficult and inefficient to properly sterilize through routine hygiene procedures. Residues inherent in food processing accumulate in these areas and form an environment that is easily colonized by bacteria, especially in the form of biofilms.
  The most common shelf life limiting organisms found in dairy processing plants are Pseudomonas species such as Pseudomonas fluorescens and Pseudomonas. These microorganisms are the most common microorganisms in frozen milk, can grow under freezing conditions, and produce many thermostable spoilage enzymes. The degradation of these enzymes directly affects the sensory properties of the final product and limits the shelf life of the processed milk. Antibiotic-resistant Staphylococcus. It is also often found in some milk processing lines in North America that the presence of staphylococci is due to the animal's own contamination due to chronic mastitis. Normal animal reviews, such as Enterococcus and Lactobacillus, have been described in dairy farms before, but obviously these are not from cattle sources.
  Obviously, the sterilization and disinfection of Duyu milk production line is an aspect that every milk manufacturer needs to pay attention to.
