| Abstract: Cyclodextrin glycosyltransferases (CGTases) are important enzymes in the biotechnology field because they catalyze starch conversion into cyclodextrins and linear oligosaccharides, which are used in food, pharmaceutical and cosmetic industries. The CGTases are classified according to their product specificity in α-, β-, α/β- and γ-CGTases. As molecular markers are the preferred tool for bacterial identification, we employed six molecular markers (16S rRNA, dnaK, gyrB, recA, rpoB and tufA) to test the identification of a CGTase-producing bacterial strain (DF 9R) in a phylogenetic context. In addition, we assessed the phylogenetic relationship of CGTases along bacterial evolution. The results obtained here allowed us to identify the strain DF 9R as... |

| Abstract A total of 48 endophytic bacteria were isolated from surface-sterilized tissues of the medicinal plant Lonicera japonica, which is grown in eastern China; six strains were selected for further study based on their potential ability to promote plant growth in vitro (siderophore and indoleacetic acid production). The bacteria were characterized by phylogenetically analyzing their 16S rRNA gene similarity, by examining their effect on the mycelial development of pathogenic fungi, by testing their potential plant growth-promoting characteristics, and by measuring wheat growth parameters after inoculation. Results showed that the number of endophytic bacteria in L. japonica varied among different tissues, but it remained relatively stable in the same... |
