This study provides new insights into the dynamics of bacterial community structure during phytoremediation. The communities of cultivable autochthonous endophytic bacteria in ryegrass exposed to polycyclic aromatic hydrocarbons (PAHs) were investigated with regard to their potential to biodegrade PAHs. Bacterial counts and 16S rRNA gene sequence were used in the microbiological evaluation. A t...

There are only few studies about the relationship of skin lesions and the percutaneous uptake of hazardous substances in exposed workers. Several aromatic amines are well known carcinogens for humans and/or animals. This case report emphasizes the relevance of dermal absorption of the aromatic amine ortho-toluidine considering four workers with different skin status (healthy, erythematous and b...

Over several hundred new compounds have been isolated from the bryophytes and more than 40 new carbon skeletal terpenoids and aromatic compounds found in this class. Most of liverworts elaborate characteristic odiferous, pungent and bitter tasting compounds many of which show, antimicrobial, antifungal, antiviral, allergenic contact dermatitis, cytotoxic, insecticidal, anti-HIV, superoxide anio...

We successfully used the guanidine isothiocyanate method for isolation of total RNA from leaf, stem, and root tissues of the aromatic plant Origanum onites. The RNA was extracted with TRI Reagent at room temperature and was recovered by isopropanol precipitation. The isolated RNA was capable of reverse transcription. The extraction method described here does not require ultracentrifugation, and...

ethiopia is remarkably rich in its biological, ecological and landscape diversity and is home to outstanding natural bio-resources such as a number of herbs, aromatic and medicinal plants. the present study was carried out to study the composition, distribution and economic importance of insect pests of prioritized aromatic (mentha sp., lemon verbena, fennel, rosemary, rosadamascene, oregano, p...

We studied the catabolism of the polycyclic aromatic hydrocarbon phenanthrene by four rhizobacterial strains and the possibility of enzymatic oxidation of this compound and its microbial metabolites by the root exudates of alfalfa (Medicago sativa L.) in order to detect the possible coupling of the plant and microbial metabolisms under the rhizospheric degradation of the organic pollutant. A co...

Pimpinella anisum (anise), belonging to Umbelliferae family, is an aromatic plant which has been used In Iranian traditional medicine (especially its fruits) as carminative, aromatic, disinfectant, and galactagogue. Because the wide traditional usage of Pimpinella anisum for treatment of diseases, in this review published scientific reports about the composition and pharmacological properties o...

linear furanocoumarins are toxic compounds synthesized by plants. these toxic natural products are usually found in the fruits of umbelliferae. heracleum persicum desf. ex fischer is an iranian aromatic medicinal plant from umbelliferae which their fruits are used as flavoring agent in food products. because of the wide usage of the fruits of h. persicum it was decided to do a phytochemical stu...

         Cell cultures of Varthemia persica DC. have been studied to evaluate their abilities in biotransformation of aromatic and aliphatic precursors. V. Persica (Asteraceae) is an aromatic plant growing in Iran. V. persica contain different terpens but its cell culture does not posses these compounds. Callus cultures of V. persica was established ...
