Lactic acid bacteria is a gram positive bacteria type, round shape (Cocci) or the (rods) is the microaerophilic or facultative. Anaerobe lactic acid producing bacteria with a focus on humans and the environment. It is very important in the food industry, and food and feed lactic acid bacteria some kind of a probiotic. Which group of beneficial bacteria in the intestines of humans can produce bacteriosin which inhibit the growth of bacteria that cause the disease. (pathogen) in the large intestine. The purpose of this research to identify the genus (Genus) and type (Species) bacteria that live in the intestines of pigs on the 5 body using molecular biology techniques. (Molecular techniques) bacteria found 3) is a Lactobacillus SP, Staphylococcus SP, Escherichia sp. By selection of specific characteristics of colonies. Lactobacillus sp. Test. The test 5 isolates Analysis of nucleotide sequence with the program BLASTN and found that both 5 isolates were all Lactobacillus by strain. Lactobacillus amylovorus 3 isolates Lactobacillus johnsonii Lactobacillus acidophilus and each 1 isolates Which this study made aware of the diversity of bacteria in the intestine that is both helpful bacteria and cause disease. As a knowledge base for use in further education that bacteria isolated might can be used effectively in various aspects of human and animals.Key words: lactic acid bacteria, pig intestine.
