Abstract - Spore-forming bacteria belonging to the genus Bacillus were isolated from brood cell provisions, honey from honey storage pots, and pollen from pollen storage pots obtained from a nest of a stingless bee, Melipona fasciata. Bacillus megaterium, B circulans, and B alvei were identified. Few other microorganisms were found. These bacteria produced a variety of enzymes including esterases, lipases, proteases, aminopeptidases, phosphatases, and glycosidases that could convert food into more digestible products for storage. Bacillus species could also secrete chemicals such as antibiotics and fatty acids to inhibit competing microorganisms which could cause spoilage of stored food, particularly in tropical environments.
