Degumming of buel (Grewia optiva) bast fibres by pectinolytic enzyme from Bacillus sp. DT7

An alkalophilic and thermotolerant, pectinase-producing Bacillus sp. DT7 effectively removed pectic substances from buel (Grewia optiva) bast fibres. A novel combined (chemical and enzymatic) treatment was used to degum buel bast fibres, which was followed by the release of galacturonic acid (575 μm...

Zusammenfassung:	An alkalophilic and thermotolerant, pectinase-producing Bacillus sp. DT7 effectively removed pectic substances from buel (Grewia optiva) bast fibres. A novel combined (chemical and enzymatic) treatment was used to degum buel bast fibres, which was followed by the release of galacturonic acid (575 μmol g^sup -1^ dry fibres) and a decrease in dry weight (43%) of these fibres.[PUBLICATION ABSTRACT]
