Diby Paul The present study was aimed at using cellulolytic bacterium Enhydrobacter and fungi Aspergillus sp. for preparing compost from rice husk (RH). Further, the prepared compost was tested for their effect on blackgram growth promotion along with different levels of recommended dose of fertilizer (RDF) in black soil (typic Haplustalf) and red soil (typic Rhodustalf) soil. The results revealed that, inoculation with lignocellulolytic fungus (LCF) Aspergillus sp. @ 2% was considered as the most efficient method of composting within a short period. Characterization of composted rice husk (CRH) was examined through sc...

AbstractA new type of magnetic bioadsorbent (CDAB) was synthesized by reaction of amidoxime modified calix[6]arene derivative with theAspergillus niger-Fe3O4 bio-nanocomposite, the bioadsorbent have been well characterized with FT-IR, SEM-EDS, XPS and VSM. The effects of various experimental parameters include pH, contact time, initial uranium(VI) concentration, adsorbent dosage and temperature on the bioadsorption of uranium(VI) were investigated in detail. Adsorption experimental results showed the adsorption process of CDAB was pseudo-second order kinetic model and Langmuir adsorption isotherm model. The maximum adsorpt...

Publication date: June 2018 Source:Medical Mycology Case Reports, Volume 20 Author(s): Yuuki Ohara, Takahiko Ito, Makoto Ito, Kyoko Yamashita, Shinya Toyokuni A 62-year-old previously healthy male who was a welder/smoker/drinker was admitted to Kani Tono Hospital for severe hypoxemia (Day 0). Initial physical and radiological examinations suggested an acute exacerbation of chronic obstructive pulmonary disease. However, respiratory failure developed rapidly, and he died on Day + 4. Aspergillus fumigatus was identified after his death, and he was diagnosed with invasive pulmonary aspergillosis. The clinical and pathologi...

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.
