Isolation and Primary Identification of Ribonuclease-producing Strain PA 110-7 from Suaedae glaucae Bunge

doi:10.7506/spkx1002-6630-201117051

Abstract

Abstract: In order to screen and identify ribonuclease-producing strain and evaluate its antiviral activity, 50 probiotics from healthy Suaedae glaucae Bunge were isolated and 9 ribonuclease-producing strains were screened by color plate method. The inhibitory activity of strain PA110-7 against Escherichia coli was 69%. Based on the analyses of colony morphology, size and color, Gram staining, spore staining, physiological-biochemical characterization and 16S rDNA sequencing, strain PA110-7 was identified as Bacillus thuringiensis.

Key words: Suaedae glaucae Bunge, probiotics, ribonuclease, isolation, identification
