Abstract

Studies show that understanding relationships of mutualism and parasitism involving the microbial community associated with insects can provide natural products with novel chemical structures and pharmacological potential. The microbial community involved with stingless bees remains unknown, such as in the case of Scaptotrigona depilis. In an ongoing PhD project it was found a high presence of Bacillus strains in the pollen of S. depilis. In addition, another Bacillus strain was isolated from the gut of larvae of S. depilis. Antimicrobial screening showed the high activity of Bacillus strains against human and insect pathogens. Since ribosomal DNA of Bacillus was found in fossils more than 20 million years in age of an extinct stingless bee, it is proposed that an ancient symbiotic relationship may exist between bees and bacteria of the genus Bacillus. To understand the ecological role of this micro-organism, the sandwich doctorate will be developed in partnership with renowned researchers from Harvard Medical School, Prof. Dr. Jon Clardy, who is a pioneer in these studies. The genome of this bacterium will be sequenced and its biosynthetic potential will be studied and compared with chemical investigations previously carried out in Brazil. To stimulate biosynthetic pathways that may be silenced, co-cultivation techniques will be carry out with the fungus Monascus ruber, isolated from S. depilis brood cells, and the extracts and their constituents will be investigated chemically and biologically.
