Prokaryotic methylotrophic bacteria are able to consume a number of C1-carbon compounds such as methane, methylamine and methanol, whereas only methanol can be consumed by eukaryotic methylotrophic bacteria as source of carbon and methylamine as a source of nitrogen. The intensive researches explain the beneficial relationship between plants and methylotrophic bacterial communities earlier. Different genera of methylotrophic yeasts such as Candida, Pichia, Torulopsis and Hansenula are able to metabolise C1 corbon compound like formaldehyde and methanol.and a number of genes are involved in the methanol and other substrate utilisation pathways such as AOX (alcohol oxidase), DAS (dihydroxyacetone synthase), FDH (format dehydrogenase) and DAK (dihydroxyacetone kinase). The phylogeny and identification of these methylotrophic yeast strains are done based on either conserved gene sequences or functional gene sequences. The current description involves the genetic diversity of different strains of methylotrophic yeast from various ecosystems, identified at gene level.
