Pathogenic bacteria are part of the pond's microflorạ Application of bacteria producing antibacterial against the pathogenic bacteria may partly or even completely replace the application of antibiotics and chemicals to culture pond.
The strain Lactobacillus plantarum L40 isolated from slime of shrimp pond
exhibited significant antibacterial activity against shrimp pathogenic bacteria,
including Vibrio parahaemolyticus. The optimal condition for growth and bacteriocin
synthesis was selected (MRS medium, 30'C, pH 6, 48-60 hours). This strain is non- toxic to shrimp and salt tolerant. Thus, it can be used in Probiotic preparation for shrimp culturẹ
