Biodiversity and biotechnological applications of novel plant growth promoting methylotrophs

The different class α, β and γ–proteobacteria of methylotrophic bacteria communities have been reported worldwide. The class α-proteobacteria has been reported as most dominant followed by β–proteobacteria. The novel methylotrophic microbes have been isolated and characterized from different habitats worldwide including Methylocella silvestris BL2T , Methylocella palustris KT, Methyloferula stellata AR4T and Methylocapsa acidiphila B2T from acidic soil;22–25 Methylobacterium tarhaniae N4211T from arid soil;26 Methylobacterium iners 5317S-33T and Methylobacterium aerolatum 5413S-11T from air sample;27 Methylobacterium adhaesivum AR27T and Methylobacterium isbiliense AR24T from drinking water;28,29 Methylobacterium brachiatum B0021T, Methylobacterium gregans 002-074T, Methylobacterium komagatae 002-079T, Methylobacterium persicinum 002-165T and Methylobacterium tardum RB677T from freshwater sample;30 Methylobacterium organophilum XX, Methylotenera versatilis 301T and Methylotenera mobilis JLW8T from lakes;31–33 Methylobacterium brachythecii 99bT, Methylobacterium cerastii C44, Methylobacterium gnaphalii 23eT, Methylobacterium gossipiicola Gh-105T, Methylobacterium haplocladii 87eT, Methylobacterium oxalidis 35aT, Methylobacterium phyllosphaerae B27T, Methylobacterium phyllostachyos BL47T, Methylobacterium platani PMB02T, Methylobacterium pseudosasicola BL36T, Methylobacterium thuringiense C34T, Methylobacterium trifolii TA73T, from leaf surface of diverse plants;34–42 Methylobacterium aminovorans TH-1, Methylobacterium goesingense iEII3, Methylobacterium soli YIM 48816T, Methylobacterium suomiense, F20T, Methylobacterium thiocyanatum, Methylobacterium variabile GR3T, Methylopila capsulata IM1T, and Methylopila helvetica VKMB-189 from soil samples43–50
