Extremozymes from metagenome: Potential applications in food processing.

The long-established use of enzymes for food processing and product formulation has resulted in an
increased enzyme market compounding to 7.0% annual growth rate. Advancements in molecular biology
and recognition that enzymes with specific properties have application for industrial production of infant,
baby and functional foods boosted research toward sourcing the genes of microorganisms for enzymes
with distinctive properties. In this regard, functional metagenomics for extremozymes has gained
attention on the premise that such enzymes can catalyze specific reactions. Hence, metagenomics that
can isolate functional genes of unculturable extremophilic microorganisms has expanded attention as a
promising tool. Developments in this field of research in relation to food sector are reviewed.
