Lactic acid bacteria are described as heterogeneous group of regular, gram-positive, rod shaped, non-motile, non-spore forming bacteria with absence of catalase enzyme. Laboratory study was undertaken to isolate and characterize the lactic acid bacteria from silkworm gut in phenotype basis. A total of 21 silkworm gut samples were collected from silkworm breeds, Double hybrid {(CSR 6 X CSR 26) X (CSR 2 X CSR 27)} obtained from Chawki rearing center (CRC) at Annur, Coimbatore. The bacteria samples were isolated after growth on MRS agar medium and pure culture was obtained by sub-culturing on the same medium. Purity of each culture was confirmed by morphological investigation, Gram’s staining and further identification were done by lactic acid bacteria through specific biochemical tests. Finally eight bacterial isolates (SWGL 6, SWGL 7, SWGL 8, SWGL 9, SWGL 10, SWGL 11, SWGL 23 and SWGL 30) were identified as lactic acid bacteria group after morphological, cultural and biochemical characterization.
