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...

Laboratory bioassay of the essential oil extracted from the grapefruit (Citrus paradisi) peel by steam distillation was carried out against the developmental stages of the yellow fever vector Aedes aegypti to evaluate its toxicity, and ovicidal and larvicidal potency. Volatile oil components isolated and characterized by coupled gas chromatography/mass spectrometry included varying levels of mo...

The relationship between carotenoid accumulation and the expression of carotenoid biosynthetic genes during fruit maturation was investigated in three citrus varieties, Satsuma mandarin (Citrus unshiu Marc.), Valencia orange (Citrus sinensis Osbeck), and Lisbon lemon (Citrus limon Burm.f.). We cloned the cDNAs for phytoene synthase (CitPSY), phytoene desaturase (CitPDS), zeta-carotene (car) des...

Some citrus flavonoids have been reported to possess antioxidant activities that moderate endothelial dysfunction and show protective effects on cardiovascular disease. We have investigated the protective effects of nobiletin (5,6,7,8,3’,4’-hexamethoxy flavone) derived from the peel of Citrus depressa Hayata (Shiikuwasha), a citrus fruit produced in Okinawa prefecture in Japan on hypertension a...

Aroma is a vital characteristic that determines the quality and commercial value of citrus fruits, and characteristic volatiles have been analyzed in different citrus species. In sweet orange, Citrus sinensis, the sesquiterpene (+)-valencene is a key volatile compound in the fruit peel. Valencene synthesis is catalyzed by the terpene synthase CsTPS1, but the transcriptional mechanisms controlli...

‘Aliza’ is a new pomelo × mandarin hybrid (Citrus maxima, cv. Red Chandler Citrus reticulata, Ora) developed by the Israeli citrus breeding program at Volcani Institute. Here, we aimed to characterize quality and flavor of fruit as compared other commercial fruit, specifically (C. maxima), grapefruit paradisi), orange sinensis) reticulata). fruits have similar size grapefruits, but thinner peel...
