Technical Abstract: Eighty-seven culturable endophytic bacterial isolates in 22 genera were obtained from coffee plants collected in Colombia (n=67), Hawaii (n=17), and Mexico (n=3). Both Gram positive and Gram negative bacteria were isolated, with a greater percentage (68%) being Gram negative. Tissues yielding bacterial endophytes included adult plant leaves, various parts of the berry (e.g., crown, pulp, peduncle and seed), and leaves, stems, and roots of seedlings. Some of the bacteria also occurred as epiphytes. The highest number of bacteria among the berry tissues sampled was isolated from the seed, and includes Bacillus, Burkholderia, Clavibacter, Curtobacterium, Enterobacter, Escherichia, Micrococcus, Pseudomonas, Serratia, and Stenotrophomonas. This is the first survey of the endophytic bacteria diversity in various coffee tissues, and the first study reporting endophytic bacteria in coffee seeds.
