Pentahydroxyscirpene—Producing Strains, Formation In Planta, and Natural Occurrence
Trichothecenes are a class of structurally diverse mycotoxins with more than 200 naturally occurring compounds. Previously, a new compound, pentahydroxyscirpene (PHS), was reported as a byproduct of a nivalenol producing Fusarium strain, IFA189. PHS contains a hydroxy group at C-8 instead of the keto group of type B trichothecenes. In this work, we demonstrate that IFA189 belongs to the species...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
The natural occurrence, enzymatic formation, and biochemical significance of a hydroxyethyl derivative of thiamine pyrophosphate.
Thiamine pyrophosphate is required as a coenzyme for several enzymatic reactions which result in the decarboxylation of cu-keto acids with the concomitant formation of corresponding aldehydes or their condensation products (a-keto alcohols). A number of investigators (l-3) have found that thiamine will catalyze the same reactions under mildly alkaline conditions in the absence of enzymes. This ...
متن کاملNatural occurrence of nivalenol and mycotoxigenic potential of Fusarium graminearum strains in wheat affected by head blight in Argentina
The principal agents of Fusarium head blight in the main cropping area of Argentina were investigated in heavily infected samples. The ability of the isolates to produce trichothecenes was determined by GC and HPLC. Fusarium graminearum was the predominant species and of 33 isolates, 10 produced deoxinivalenol (DON) (0.1- 29 mg kg(-1)), 13 produced both deoxinivalenol (1.0- 708 mg kg(-1)) and n...
متن کاملThe natural occurrence and enzymatic formation of a hydroxyethyl derivative of thiamine pyrophosphate.
Breslow (1) has formulated a mechanism of thiamine action in which the Z-position of the thiazolium ring of thiamine is postulated to be the reactive part of the molecule. Krampitz et al. (2) have prepared thiamine with an cr-hydroxyethyl group substituted on the Z-position and reported its probable identity as “active acetaldehyde.” Recent results from thii laboratory indicate that the pyropho...
