The production of β-glucosidases by Fusarium proliferatum NBRC109045 isolated from Vietnamese forest
Fusarium
proliferatum NBRC109045 is a filamentous fungus isolated from
Vietnamese forest due to high production of β-glucosidases. Production
of the enzyme was studied on varied carbon source based mediums. The
highest activity was obtained in medium containing 1% corn stover + 1%
wheat bran (3.31 ± 0.14 U/ml). It is interesting to note that glucose
(0.69 ± 0.02 U/ml) gave higher activity and just followed by cellobiose
among the di- and mono-saccharides, which is generally regarded as a
universal repressor of hydrolases. We improved the zymogram method to
prove that in response to various carbon sources, F. proliferatum could
express various β-glucosidases. One of the β-glucosidases produced by F.
proliferatum growing in corn stover + wheat bran based medium was
partially purified and proved to have high catalytic ability.
