Isolation and characterization of a psychrophilic xylanase enzyme from flavobacterium sp. Current Microbiology, 52(2):112-116. Interpretive Summary: Renewable energy demand in the future will only be met if we can utilize biomass sources such as agriculturally derived wastes (straws and bagasse). Critical to successful use of these biomass sources is development of enzymes, such as xylanases, that will break the plant cell wall down into usable fractions. Xylan is a renewable resource that can potentially be used to supply significant portions of our fuel and chemical feedstock needs. Xylanases are enzymes that hydrolyze the xylan substrate in order to make it more readily usable. Industry requires xylanases that have different activity profiles depending on the conditions of any specific process. Thus, there is interest in isolating more xylanases with different activities. We have discovered a xylanase enzyme with high specific activity at cold temperatures. This enzyme might be useful for industrial processes such as baking.
