Mycelium-bound lipase from a locally isolated strain of Aspergillus flavus link: pattern and factors involved in its production
Aspergillus flavus produces a lipase (EC 3.1.1.3) which is partly bound to the mycelium during growth. The production of the mycelium-bound lipase is concomitant with growth, and declines when growth ceases. Maximum productivity of the enzyme is obtained when the culture is incubated at 30°C, an initial culture pH of 6·5 and with 2% (w/v) each of corn oil and yeast extract as carbon and organic...
متن کاملAnalysis of Soil Populations of Aspergillus flavus Link. from Pistachio Orchards in Iran for Vegetative Compatibility
One hundred-thirty soil isolates of A. flavus were collected from commercial pistachio orchards in two main production regions including Rafsanjan (Kerman Province, south-eastern of Iran) and Damghan (Semnan Province, central north of Iran) and assayed for vegetative compatibility groups (VCGs). The sixteen and twenty VCGs were identified for 41 and 37 nit-mutant producing isolates of A. flavus...
متن کاملPotential of essential oils for protection of grains contaminated by aflatoxin produced by Aspergillus flavus
Aflatoxin B1 (AFB1) is a highly toxic and carcinogenic metabolite produced by Aspergillus species on food and agricultural commodities. Inhibitory effects of essential oils of Ageratum conyzoides (mentrasto) and Origanum vulgare (oregano) on the mycelial growth and aflatoxin B1 production by Aspergillus flavus have been studied previously in culture medium. The aim of this study was to evaluate...
متن کاملNitrification by Aspergillus flavus.
Marshall, K. C. (Cornell University, Ithaca, N. Y.) and M. Alexander. Nitrification by Aspergillus flavus. J. Bacteriol. 83:572-578. 1962.-Aspergillus flavus has been shown to produce bound hydroxylamine, nitrite, and nitrate when grown in peptone, amino acid, or buffered ammonium media. Free hydroxylamine was not detected in these cultures, but it was found in an unbuffered ammonium medium in ...
متن کاملScreening of Essential Oils of Angiospermic Plants for Their Fungitoxicity against Aspergillus Flavus and Aspergillus Niger
Essential oils obtained from plants have recently gained a great scientific interest as a potent source of antimicrobials of natural origin. The present study highlights the antifungal activity of essential oils against Aspergillus flavus and Aspergillus niger. During screening of essential oils of six selected Angiospermic plants at 2000 ppm (mg/l) against the test fungus, Mentha arvensis and ...
