In order to qualitative and quantitative study on essential oil, obtained from leaf and peel of Citrus aurantium L. cultivated in North of Iran (Sari city) the leaves and fruits were gathered on April and November 2002, respectivelly. Clevenger apparatus was used for hydro-distillation extraction in order to provide the oil of leaf and peel of Citrus aurantium L. The outputs of each essential o...

Orange essential oil (OEO) is mainly composed of D-Limonene and other oxygenated compounds that contribute to the orange flavor aroma. However, unstable in presence heat, light, water, affecting quality OEO. Therefore, objective this study was fractionate OEO by distillation, both molecular fractionated (hybrid), producing a D-Limonene-rich fraction. The characterized physicochemical tests gas ...

In this study, the characterization of fatty acids and secondary metabolites in seeds three cultivars Opuntia ficus-indica L. (O. ficus-indica, yellow, orange, green) harvested from Souk Ahras area Northeast Algeria was performed. The antioxidant activity seed extracts also assessed by using two methods, namely FRAP DPPH tests. Results show that total phenolic content (TPC) ranged 63.02 to 81.8...

The habitual consumption of marine fish is largely associated to human mental health. Fish oil is particularly rich in n-3 polyunsaturated fatty acids that are known to play a role in several neuronal and cognitive functions. In parallel, the orange-pinkish carotenoid astaxanthin (ASTA) is found in salmon and displays important antioxidant and anti-inflammatory properties. Many neuronal dysfunc...

Seventeen microbial species including 10 fungal taxa, two yeasts and five bacteria, were isolated from freshly prepared orange, guava and banana juices kept in open bottles at room temperature for 7 days. Eight different essential oils, from local herbs, were tested for their antimicrobial activity against these test organisms. The essential oils of Cymbopogon citratus, Ocimum basilicum and Ori...

Helaeomyia petrolei larvae isolated from the asphalt seeps of Rancho La Brea in Los Angeles, Calif., were examined for microbial gut contents. Standard counts on Luria-Bertani, MacConkey, and blood agar plates indicated ca. 2 x 10(5) heterotrophic bacteria per larva. The culturable bacteria represented 15 to 20% of the total population as determined by acridine orange staining. The gut itself c...

The present work was carried out with an aim to isolate an Exo-pectinase producing fungal strain, to optimize physical factors of the enzyme activity and to formulate a media for the cost effective production of the enzyme. Screening, isolation and identification of Aspergillus tamarii and Aspergillus carbonarius were done. Various process variables like pH, temperature and incubation time of t...
