Diversity of cultivable bacteria associated with fruiting bodies of wild Himalayan Cantharellus spp.

The cultivable bacteria associated with fruiting bodies of different Cantharellus species collected from the forests of the north-western Himalayan region were studied. Repetitive extragenic palindromic (REP) and BOX-PCR fingerprinting analyses revealed that different strains were distributed within Cantharellus species. The number of bacteria varied from 0.5 to 1.1 x 10(3) CFU/g of fresh tissue for different fruiting bodies. Thirty different operational taxonomic units (OTUs) were found among the bacteria analyzed. 16S rRNA sequence analysis revealed that most of the bacteria associated with different Cantharellus species were Gammaproteobacteria belong to the genera Hafnia, Enterobacter, Ewingella, Rahnella, Stenotrophomonas, and Pseudomonas, and gamma-proteobacterium, followed by Betaproteobacteria (Alcaligenes) and Firmicutes, (Bacillus). The most common bacteria associated with the majority of Cantharellus species were Hafnia and Stenotrophomonas species.
