Among all the aromatic compounds phenol is the major constituent of soil contaminated form many industries. Toxicity of phenol is well recognized for human as well as environment. In future, microbial system is the potential tool to deal with environmental pollutants like phenol. In the present study, an aerobic bacterial culture was isolated from oil contaminated soil by enrichment technique a...
Biochemical evaluation of resistance responses of potato to different isolates of Alternaria solani.
The resistance phenotypes of nine potato cultivars to five isolates of Alternaria solani, causal agent of early blight, were studied after inoculation and growth under greenhouse conditions. We identified potato cultivars with both susceptible and resistant phenotypes as well as A. solani isolates with varying degrees of aggressiveness. Two potato cultivars and two pathogen isolates were select...
A comparison of electrochemical degradation of phenol on boron doped diamond and lead dioxide anodes
This work compares two electrode materials used to mineralize phenol contained in waste waters. Two disks covered with either boron doped diamond (BDD) or PbO2 were used as anodes in a one compartment flow cell under the same hydrodynamic conditions. Efficiencies of galvanostatic electrolyses are compared on the basis of measurements of Total Organic Carbon (TOC) and Chemical Oxygen Demand (COD...
We assessed the polyphenolic contents and antioxidant potential of the aqueous, ethanol and methanol stem bark extracts of Jatropha curcas. The total phenol, flavonoids, flavonols and proanthocyanidin contents of the extracts were evaluated to determine their effect on the antioxidant property of this plant, using standard phytochemical methods. The antioxidant and free radical scavenging activ...
Background & Aims: The aim of this study was to evaluate and compare the antioxidant activity and the collecting rate of free radicals in the environment of in vitro, by utilizing the methanol’s extracts from different parts of the plants such as Plantago major, Trifolium subterraneum, Boswellia thurifera, Juglans regia (walnut). Materials & Methods: Antioxidant and antiradica...
introduction: all fruits that called citrus are from rutaceae family and aurantioideae subfamily. this subfamily have more than 33 different genus that only three of its genus (citrus, poncirus and fortunella) have economic aspects and in citrus producing country are important. it's reported that orange skin has a phenolic compounds which play a role in natural defense mechanism. also various c...
In cells of Rhodococcus opacus GM-14, GM-29, and 1CP, the contents of branched (10-methyl) fatty acids increased from 3% to 15 to 34% of the total fatty acids when the cells were grown on benzene, phenol, 4-chlorophenol, chlorobenzene, or toluene as the sole source of carbon and energy, in comparison with cells grown on fructose. In addition, the content of trans-hexadecenoic acid increased fro...
ONE of the major problems associated with the disinfection of water supplies by chlorination is that the organoleptic properties of the chlorinated water may be increased. This malodorous water is often produced by a reaction between the added chlorine and trace concentrations of organic compounds present in the water. By far the most notorious of the organic compounds found in water which incr...
lemon verbena (lippia citriodora) belongs tothe verbenaceae (shahpasand) family.l.citriodora is chemical composition of the leaves plant have antimicrobial properties, refrigerant,anti-headaches one-sided, anti- pains nerve and housing, carminative, helping to digestion, relaxation, dizziness, colds therapy, memory booster and etc. in this study, phenolic compounds of l.citriodoraleaves were...
the effect of the organic, integrated and conventional methods of kiwifruit cv. 'hayward' production on the fruit quality at its harvest time was investigated. such traits as fruit size, firmness, total soluble solids (tss), titratable acidity (ta), total chlorophyll, total carotenoids, vitamin c, total phenol, flavonoid compounds (catechin, quercetin 3-glucoside and chlorogenic acid)...
