Isolation and Identification of a Strain of Aspergillus Tubingensis With Deoxynivalenol Biotransformation Capability
Deoxynivalenol (DON) is one of the most common contaminants of various foodstuffs. A biotransformation system was used in order to lessen the toxicity of DON. A strain of Aspergillus (NJA-1) was isolated from soil and cultured in an inorganic salt medium containing DON. Bt2a/Bt2b primers were used to amplify the beta-tubulin gene of NJA-1. Sequence analysis the PCR product and morphology observ...
متن کاملInfectious keratitis caused by Aspergillus tubingensis.
PURPOSE To report 2 cases of keratomycosis caused by Aspergillus tubingensis. METHODS The therapeutic courses were recorded for 2 male patients, 52 and 78 years old, with fungal keratitis caused by black Aspergillus strains. Morphological examination of the isolates was carried out on malt extract agar plates. A segment of the beta-tubulin gene was used for molecular identification. Antifunga...
متن کاملHuman and Plant Fungal Pathogens: The Role of Secondary Metabolites
Secondary metabolites (SM) are small organic molecules produced by various microorganisms (mainly fungi and actinobacteria, among others) through the action of large enzymes like nonribosomal peptide synthetases (NRPS) and polyketide synthases (PKS) or by enzymes like dimethylallyl transferases and prenyltransferases. These special metabolites are in general not essential for growth but are bel...
متن کاملFungal metabolites from Aspergillus niger AN27 related to plant growth promotion.
Two metabolites have been isolated from Aspergillus niger AN27, a biocontrol agent, and identified as 2-carboxymethyl 3-n-hexyl maleic acid (compound 1) and 2-methylene-3-hexylbutanedioic acid (compound 2). Their biological activities related to crop growth promotion have been assayed. Both the compounds increased germination and improved crop vigour. Compound 1 was more effective for increase ...
متن کاملextraction and characterization of allium irancum plant extract and its application in the green synthesis of silver nano particles and oxidation of thiocarbony1 compounds
سنتز سبز نانوذرات فلزی (nps) درسالهای اخیر توجه بسیارزیادی را به خود جلب کرده است. زیرا این پروتوکل کم هزینه وسازگار با محیط زیست از روش های استاندارد سنتز. در این پایان نامه ما گزارش میکنیم یک روش ساده و سازگار با محیط زیست برای سنتز نانوذرات نقره با استفاده از محلول آبی عصاره گیاه allium iranicum به عنوان یک عامل کاهش دهنده ی طبیعی. نانو ذرات نقره مشخص شد با استفاده از تکنیک های uv-visible، x...
