Pyrosequencing analysis of the bacterial communities in the guts of honey bees Apis cerana and Apis mellifera in Korea.

The bacterial communities in the guts of the adults and larvae of the Asian honey bee Apis cerana and the European honey bee Apis mellifera were surveyed by pyrosequencing the 16S rRNA genes. Most of the gut bacterial 16S rRNA gene sequences were highly similar to the known honey bee-specific ones and affiliated with Pasteurellaceae or lactic acid bacteria (LAB). The numbers of operational taxonomic units (OTUs, defined at 97% similarity) were lower in the larval guts (6 or 9) than in the adult guts (18 or 20), and the frequencies of Pasteurellaceae-related OTUs were higher in the larval guts while those of LAB-related OTUs in the adult guts.

Pedobacter rhizosphaerae sp. nov. and Pedobacter soli sp. nov., isolated from rhizosphere soil of Chinese cabbage (Brassica campestris).

Two bacterial strains, 01-96(T) and 15-51(T), isolated from rhizosphere soil of Chinese cabbage (Brassica campestris) were characterized by using a polyphasic approach. 16S rRNA gene sequence analysis showed that strain 01-96(T) was phylogenetically related most closely to Pedobacter suwonensis 15-52(T) and Pedobacter roseus CL-GP80(T) (96.7 and 96.
