Lipase production of Aspergillus oryzae

Journal of Fermentation and Bioengineering, 1994
Aspergillus oryzae produced a small amount of lipase (0.05–0.8 U/wet-g of solid medium) in solid cultures, in contrast to the larger amount (0.46 U/ml) in a shake-flask culture in a modified GYP medium containing 2% glucose, 1% yeast extract and 2% Polypepton. Optimum conditions of lipase production in the submerged culture of A. oryzae were determined

Comparative Genome Analysis of Aspergillus Oryzae and Aspergillus Flavus

Proceedings of the 2019 8th International Conference on Bioinformatics and Biomedical Science, 2019
Aspergillus oryzae is widely used for the industrial production of traditional fermentation, while Aspergillus flavus can produce strong carcinogenic and teratogenic aflatoxin. However, they are very similar in morphology and difficult to be distinguished from each other. In this paper, the genome sequences of A. oryzae and A.

Allergic Bronchopulmonary Aspergillosis due to Aspergillus oryzae

Chest, 1987
A 19-year-old female student with allergic bronchopulmonary aspergillosis (ABPA) due to Aspergillus oryzae is reported. This organism was used for fermentation starter to make soybean paste in her father's workshop adjacent to the home where she lived. ABPA might be considered an occupational disease in certain situations.

Bioconversion of Capsaicin by Aspergillus oryzae

Journal of Agricultural and Food Chemistry, 2015
This study identified metabolites of capsaicin bioconverted by Aspergillus oryzae, which is generally used for mass production of gochujang prepared by fermenting red pepper powder in Korea. A. oryzae was incubated with capsaicin in potato dextrose broth. Capsaicin decreased depending on the incubation period, but new metabolites increased.

Repetitive attack by Aspergillus oryzae alpha amylase

Carbohydrate Research, 1978
The action of Aspergillus oryzae alpha amylase on reducing-end, and uniformly radiolabeled maltotriose through maltodecaose has been studied. The enzyme is found to hydrolyze more than a single glycosidic bond during enzyme-substrate encounters. The extent of this repetitive attack is quantitated.

Invasion of paranasal sinuses by Aspergillus oryzae

Mycopathologia, 1986
A 24-year-old male patient receiving chemotherapy for acute promyelocytic leukemia developed fever, right periorbital swelling and mild right proptosis. A head scan showed opacification of the right maxillary and ethmoid sinuses with adjacent soft tissue swelling. Biopsy of the nasal mucosa demonstrated the typical septate hyphae of Aspergillus species

Alkaline protease from Aspergillus oryzae: Esterase activity

Biochimica et Biophysica Acta (BBA) - Enzymology, 1972
Abstract Kinetic data are presented for the hydrolysis of N-substituted amino acid esters by aspergillopeptidase B, an alkaline protease from Aspergillus oryzae. The rate of hydrolysis was followed with a pH-stat at pH 8.5, 25°C and ionic strength 0.1.

Telomere-mediated chromosomal truncation in Aspergillus oryzae

Journal of Bioscience and Bioengineering, 2015
We truncated the short arm of chromosome 3 to delete the aflatoxin biosynthesis gene homolog cluster using telomeric repeats in Aspergillus oryzae. The predicted deletion was confirmed by Southern blot analyses. This telomere-mediated chromosomal truncation method enables the development of an artificial chromosome in A. oryzae.

Biosynthesis of l-DOPA by Aspergillus oryzae

Bioresource Technology, 2002
The present investigation deals with the biosynthesis of L-DOPA by parental (GCB-6) and mutant (UV-7) strains of Aspergillus oryzae. There was a marked difference between the mycelial morphology and pellet type of parental and UV-irradiated mutant culture. The mutant strain of A.

Crystals of β-Xylanase from Aspergillus oryzae

Journal of Molecular Biology, 1993
An endo-xylanase was isolated from the culture of fungus Aspergillus oryzae variant D5. The purified enzyme had a molecular weight of 24,000 and the isoelectric point of 3.6. Xylanase crystals were obtained from a polyethylene glycol 6000 solution by the hanging-drop method. Seeding was used for the enlargement of the crystal size.
