Abstract: PURPOSE: Provided is a method for manufacturing antibody of E. coli O157:H7 in a high yield by using eggs which can be more easily obtained than blood of rabbits to prevent food poisoning beforehand and help farmers increase their income. CONSTITUTION: A method for manufacturing antibody of E. coli O157:H7 is characterized by the next steps of: i) cultivating E. coli O157:H7 in brain heart infusion broth, killing the bacteria in water of 90-100 deg.C for 5-10 minutes, and centrifuging the broth to obtain only the bacteria; ii) using a sonicator to destroy E. coli, and washing and drying the destroyed bacteria; iii) mixing 1-5 mg of dried bacteria, 0.5 ml of PBS buffer solution (pH 7.2), and 0.5 ml of Freund's complete adjuvant to make an antigen; iv) inserting the antigen into hens about to lay eggs and repeating the process two weeks later; v) selecting eggs 40- 60 days after the insertion; vi) separating immunoglobin Y from the eggs and storing the antibodies at 4 deg.C for 6-12 hours; vii) centrifuging the antibodies at 7,000 rpm for 20 minutes to obtain supernatant and drying the antibodies; and viii) mixing dried antibodies with the eggs of step (v) and freezing the eggs to increase the amount of antibodies.

Abstract: PURPOSE: A method for incubating lactic acid bacteria(LAB) isolated from the stomach of pigs is provided, thereby the activity decrease and denaturation of LAB can be inhibited during the incubation of lactic acid bacteria. CONSTITUTION: The lactic acid bacteria Lactobacillus casei (ATCC 334), which has high acid tolerance and antimicrobial activity, is isolated from the stomach of pigs. The Lactobacillus casei (ATCC 334) is incubated in an MRS medium further containing 0.003% of riboflavin and 0.005% of nicotinic acid as essential nutrients, 0.005% of hydrochloric acid and 0.001% of pyridoxal as growth stimulators in order to maintain its activity and not to occur denaturation of LAB during incubation, and eventually to reach to the intestine of animals when animals uptake LAB.
