HPLC/MS analysis of fusarium mycotoxins, fumonisins and deoxynivalenol.
Fusarium fungi are widely found in agricultural products, worldwide and can produce a great variety of mycotoxins. Fumonisins, produced by F. moniliforme, and deoxynivalenol, produced by F. graminearum, are two such mycotoxins that have received considerable attention as food safety concerns by regulatory agencies. High Performance Liquid Chromatography/Mass Spectrometry (HPLC/MS) was found to ...
متن کاملNatural Contamination with Mycotoxins Produced by Fusarium graminearum and Fusarium poae in Malting Barley in Argentina
Two of the most common species of toxin-producing Fusarium contaminating small cereal grains are Fusarium graminearum and F. poae; with both elaborating diverse toxins, especially deoxynivalenol (DON) and nivalenol (NIV), respectively. The objective of our work during the 2012-2014 growing seasons was to screen crops for the most commonly isolated Fusarium species and to quantify DON and NIV to...

of the most resistant two-rowed barley accessions identified is CIho 4196 (Prom et al., 1996; Takeda, 1992). Fusarium head blight (FHB), incited by Fusarium graminearum This accession originates from China and is being used Schwabe [telomorph Gibberella zea (Schwein)], has caused devastating losses to yield and quality of barley (Hordeum vulgare L.) proextensively as a parent by the six-rowed b...
متن کاملNatural occurrence of Fusarium mycotoxins (trichothecenes and zearalenone) in barley and corn in Korea.
Barley is produced in four provinces, Chonbuk, Chonnam, Kyungbuk, and Kyungnam, and corn is mainly produced in the Kangwon province in Korea. The natural occurrence of Fusarium mycotoxins was surveyed in 39 barley and 46 corn samples from different areas. Five 8-ketotrichothecenes, namely deoxynivalenol (DON), nivalenol (NIV), 4-acetylnivalenol (4-ANIV), 3-acetyldeoxynivalenol (3-ADON), and 4,1...

آنزیم تریپسین در شرایط قلیایی ناپایدار می باشد .و فعالیت پروتئولیتیکی تریپسین منجربه خود هضمی آن در جایگاههای خاصی می گردد. بنابر این آنزیمی با ناپایداری بالا محسوب میگردد. در سالهای اخیر موفق شدند که با ایجاد تغیرات شیمیایی با اضافه کردن فلزات خاص ، کلسیم و یا عمل استیلاسیون منجر به افزایش پایداری آنزیم تریپسین گردند. مطالعات در حال حاضر نشان می دهد که تریپسین استیله شده فعالیت آنزیمی خود را ...
