Abstract: | Mannans are the major constituents of the hemicellulose fraction in softwoods and show widespread distribution in plant tissues.
The major mannan-degrading enzymes are β-mannanases, β-mannosidases and β-glucosidases. In addition to these, other enzymes
such as α-galactosidases and acetyl mannan esterases, are required to remove the side chain substituents. The mannanases are
known to be produced by a variety of bacteria, fungi, actinomycetes, plants and animals. Microbial mannanases are mainly extracellular
and can act in wide range of pH and temperature because of which they have found applications in pulp and paper, pharmaceutical,
food, feed, oil and textile industries. This review summarizes the studies on mannanases reported in recent years in terms
of important microbial sources, production conditions, enzyme properties, heterologous expression and potential industrial
applications. |
