Screening and Identification and Study on Antimicrobial Activity of Bacterial Isolates from Honey

Abstract:

Eight Bacillus strains were screened out successfully from four honey samples.Theses strains were identified by colony morphology,physiological and biochemical characteristics,and 16S rRNA gene sequence analisis.Eight isolates exhibited antimicrobial activity against Escherichia coli,Shigella dysenteriae S7NaCl and Serratia marcescens SYBCT02.Based on the study of antimicrobial activity by the isolates of bacteria,it was found that some strains might inhibit other colonies growth through competitive,and some strains might inhibit other colonies growth by its metabolism produced inhibitory substances.
