A study was conducted to isolate and identity strain of lactic acid bacteria (LAB) isolated from king grass, and to determine their potential as candidate of probiotic for livestock. The LAB was isolated by culturing king grass extract in De Man, Rogosa and Sharpe (MRS) medium. The pure culture LAB was used to identity strain of bacteria using Analytical Profile Index (API) 50 CH kit. The result showed that the strain bacteria was identified as Lactobacillus plantarum. L. plantarum was able to survive in extreme condition at pH 2 and 0.3 percent bile salt. L. plantarum also survived against pathogenic bacteria i.e. Staphylococcus aureus, Escherechia coli and Salmonella thypi. It is concluded that L. plantarum isolated from king grass could potentially to be used as probiotic for livestock.
