Isolation of Probiotic Bacteria from Guppy Poeciliareticulata (Cyprinodontiformes:Poecilidae)

Özet

The screening possibility of some Lactobacillus sp. bacteria with potential probiotic properties from digestive tract ofguppywas investigated in this study.To this end, forty -nine bacterial isolates derived from the digestive tract of the guppywere screened based on the morphological and microscopic characteristics like Catalase test, Gram staining and Sporestaining. Then, other examinations for selecting the bacteria with the best potential probiotic properties were done, including:functional antagonist assay, cell surface hydrophobicity, and resistance to acid and bile salts. Additionally,16SrRNA fragmentof the isolates with probiotic characteristics depicted 100% sequence identity with Weissellacibaria. According to our results,W. cibariahas the potential probiotic characteristics to apply in the culture of guppy.
