Potencial biotecnológico de bactérias isoladas do alimento larval de abelhas sem ferrão nativas do Brasil como bioestimulante

Abstract

Bacteria isolated from stingless bees have proven to be promising sources ofbiomolecules due to their antioxidant, anti-inflammatory, enzymatic, and antimicrobial effects, with great biotechnological potential for industry, agriculture, and healthcare. Currently, in agriculture, studies are exploring the prospect of microorganisms capable of protecting seeds and accelerating the germination process without harming the environment or public health. Thus, the study aimed to evaluate the biotechnological potential of bacteria isolated from stingless bee larval food, with biostimulant action. To this end, bacteria from the Collection of Microorganisms Isolated from Stingless Bees of the Genetics Laboratory of the Federal University of Uberlândia were selected for testing. The experiment was conducted in vitro, where seeds were soaked with the supernatant of each test bacterium and incubated for 7 days at 25°C in a gerbox with absorbent paper moistened with distilled water. Controls consisted of incubating untreated seeds. Germination time, root size, and cotyledon size were assessed daily. As a result, the MS11 and MS29 supernatants showed significant results for biostimulant activity.
