Meiothermus sp. sk3-2: a potential source for the production of trehalose from maltose
Trehalose has similar chemical formula as maltose. In terms of price, trehalose is much more expensivethan maltose. A pink-pigmented bacterium identified as Meiothermus sp. SK3-2 was found to be able to convert maltose to trehalose. Based on fatty acids analysis, the Meiothermus sp. SK3-2 may be a n...
