- Abstract
Lactic acid bacteria are widely distributed in intestinal tracts of various animals where they live as normal flora.Strains of lactic acid bacteria are the most common microbes employed as probiotics, The optimum condition for growth are important to mass production and to determined parameters most suitable for growth. The effects of temperature, pH and salinity on the growth and production of lactic acid from the three shrimp intestinal lactic acid bacteria isolates were conducted using bacth culture in a flask. These variables for growth were determined based on the growth curves and lactic acid production. Data from the flask batch experiment demonstrated that the best initial pH and temperature for growth of isolat L12 ,L14 and L21 were found to be pH 6 and 30 OC. Salinity (NaCl concentration) 0,75% were the best for growth of isolat L12. Salnity 1,5 % were best for growth of isolat L14 and L21.
