Bioproduction of Indole Acetic Acid by Rhizobium Strains Isolated from Root Nodules of Green Manure Crop, Sesbania sesban (L.) Merr.
Twenty six Rhizobium strains were isolated from root nodules of Sesbania sesban (L.) Merr. collected from different regions of Andhra Pradesh. All the 26 Rhizobium strains produced indole acetic acid (IAA), but maximum amount was produced by only five strains in yeast extract mannitol (YEM) medium supplemented with L-tryptophan. The strains were found to elaborate maximum IAA when fed with 2.5...
متن کاملOta-producing Fungi in Foodstuffs: a Review
Ochratoxin A (OTA) is a secondary metabolite produced by filamentous fungi of the genera Aspergillus and Penicillium present in a wide variety of foodstuffs. The most relevant OTAproducing species are Penicillium verrucosum (P. verrucosum), Aspergillus ochraceus (A. ochraceus), A. niger and A. carbonarius due to their prevalence in foodstuffs (cereals, grapes, coffee, etc.) and the number of st...
متن کاملA review of phenolic antioxidants isolated from endophytic fungi
Oxidative stress caused by overproduction of free radicals or oxygenated radical species plays a major role in causing many diseases. The findings suggest the use of antioxidants as compounds to control the release of these radicals or directly prevent their formation. Therefore, antioxidants can be used as drugs to reduce or prevent oxidative stress. Herbal medicines are the basis of modern ph...
متن کاملMycotoxins: Producing Fungi and Mechanisms of Phytotoxicity
Mycotoxins are secondary fungal metabolites, toxic to humans, animals and plants. Among the hundreds of known mycotoxins, aflatoxins, citrinin, patulin, penicillic acid, tenuazonic acid, ochratoxin A, cytochalasins, deoxynivalenol, fumonisins, fusarin C, fusaric acid, and zearalenone are considered the types that most contaminate cereal grain. The majority of the mycotoxins in these groups are ...
متن کاملBiodegradation of ochratoxin A by fungi isolated from grapes.
Ochratoxin A is a mycotoxin present in several food products for which levels should be reduced. Chemical, physical, and biological methods have been proposed for the detoxification of mycotoxins, biological methods being the more promising ones. In this report, filamentous fungi isolated from Portuguese grapes were assessed for ochratoxin A degradation capabilities. It was observed that 51 of ...
