Abstract

The aim of this study was to isolate sporogenic bacteria from the honey of stingless bees Melipona sp., in dry forest, and to evaluate their antagonistic potential for medicinal employment purposes and animal production. The honey samples were collected in Serra Talhada-PE, where honey was taken from four different hives (in triplicate), totaling 12 samples. The samples were diluted and subjected to 80 ºC for 20 minutes to eliminate vegetative cells. The dilutions were plated onto nutrient agar and incubated at 30 ºC for 72 hours. Then the colony forming units (CFU) were quantified. The samples were also plated onto malt agar and Sabouraud agar, and incubated at 30 ºC for 14 days for the growth of yeast and molds. Total and fecal coliforms were quantified by the most probable number method (MPN). Seven isolates (I) of sporogenic bacteria (Bacillus) were obtained, however only four showed probiotic potential. Isolate I-5 showed the greatest probiotic potential and inhibited the growth of Escherichia coli, Klebsiella sp., Pseudomonas aeruginosa, Salmonella sp., and Staphylococcus aureus. The growth of the Sarcina sp. was not inhibited by any isolate. No yeast, molds or coliforms were found. The Melipona sp. honey is a source of spore-forming bacteria and is antagonistic to microorganisms that contaminate honey. It has good microbiological quality.
