Publication date: 15 July 2018 Source:Food Chemistry, Volume 254 Author(s): Jia Wu, Shanshan Jin, Shanshan Wu, Yifan Chen, Ruiwei Chen Oat bran was fermented by filamentous fungi to improve the extractability of β-glucan. Box-Behnken experimental design and response surface methodology were used to obtain the maximum extractability of β-glucan. Inoculum volume, fermentation temperature, and time were evaluated as three variables. Under optimal fermentation conditions, the extractability of β-glucan in oat bran increased to 45.57 ± 1.82% and 51.10 ± 2.32% by Aspergillus niger and Rhizop...

The UbiD family of reversible decarboxylases act on aromatic, heteroaromatic, and unsaturated aliphatic acids and utilize a prenylated flavin mononucleotide (prFMN) as cofactor, bound adjacent to a conserved Glu–Arg–Glu/Asp ionic network in the enzyme's active site. It is proposed that UbiD activation requires oxidative maturation of the cofactor, for which two distinct isomers, prFMNketimine and prFMNiminium, have been observed. It also has been suggested that only the prFMNiminium form is relevant to catalysis, which requires transient cycloaddition between substrate and cofactor. Using Aspergillus niger Fdc1...

We describe here the production of an acid-stable recombinant inulinase from Aspergillus kawachii in the Pichia pastoris system and the recombinant enzyme's biochemical characteristics and potential application to industrial processes. After an appropriate cloning strategy, this genetically engineered inulinase was successfully overproduced in fed-batch fermentations, reaching up to 840 U/ml after a 72-h cultivation. The protein, purified to homogeneity by chromatographic techniques, was obtained at a 42% yield. The following biochemical characteristics were determined: the enzyme had an optimal pH of 3, was stable for at ...

Conclusions This study illustrates that a gene family can encode multiple enzymes members having remarkable differences in biochemical properties. It provides not only new insights into evolution and functional divergence among different members of an α-amylase family, but the development of new enzymes for industrial application.
