This research work focused on the production of biofuel from orange peels using Bacillus subtilis as a fermentor. The were collected Ekeukwu market and Ihiagwa fruit center, Owerri Nigeria, sun dried grinded manually to powder. sample was further fermented for 8days subtilis, after which it distilled 6 hours in order extract biofuel.Analysis ethanol compostion carried out gas chromatography.The...

Abscisic acid (ABA) significantly stimulated ethylene production in citrus (Citrus sinensis [L.] Osbeck, cv Shamouti orange) leaf discs. The extent of stimulation was dependent upon the concentration of ABA (0.1-1 milimolar) and the duration of treatment (15-300 minutes). Aging the discs before applying ABA increased ABA-induced ethylene production due to enhancement of both ethylene-forming en...

larvae of dicrodiplosis manihoti harris (dip., cecidomyiidae) are the predator of mealybug ovisacs (hem.: pseudococcidae) in fars province, iran. parasitized larvae of this predator were collected from nipaecoccus viridis (newstead) on citrus sinensis (l.) and reared in the laboratory. parasitoid wasps belonging to the family torymidae were consequently collected, and identified as pseudotorymu...

Plant tryptophan decarboxylase (TDC) converts tryptophan into tryptamine, precursor of indolealkylamine alkaloids. The recent finding of tryptamine metabolites in Citrus plants leads to hypothesize the existence of TDC activity in this genus. Here, we report for the first time that, in Citrus x limon seedlings, deuterium labeled tryptophan is decarboxylated into tryptamine, from which successiv...

In citrus blight, a decline disorder of unknown etiology, the tree canopy exhibits symptoms of Zn deficiency while Zn accumulates in the trunk phloem. We have purified a Zn-binding protein (ZBP) from phloem tissue of healthy and blight-affected citrus (Citrus sinensis [L.] Osbeck on Citrus jambhiri [L.]). The molecular weight of the ZBP was estimated to be 5000 by size-exclusion chromatography ...

Continued application of synthetic insecticides arise development of resistance and pollution of the environment. Laboratory experiments were conducted to test the efficacy of products of orange (Citrus sinensis) peels in the control of the stored products beetle Zabrotes subfasciatus (L) in stored haricot beans (latin name). Different levels of the extracts and essential oil of Citrus sinensis...

BACKGROUND This work aims at describing the traditional uses, to determine the antimicrobial potential of two different extracts hexane, acetone of the leaves of Citrus unshiu, Citrus sinensis, Citrus limon, Laurus nobilis, Citrus paradisi on clinical strain of H. pylori in a bid to identify potential sources of cheap starting materials for the synthesis of new drugs. H. pylori strain was a cul...

This study was carried out in the Counties of Montenegro and Pareci Novo located in the region of the Vale do Rio Cai, Rio Grande do Sul, Southern Brazil, aiming to determine the fruit fly species of Tephritidae and Lonchaeidae that occur in organic orchards of sweet orange [Citrus sinensis (L.) Osb.] cultivar Céu, and Murcott tangor (Citrus reticulata Blanco x C. sinensis), during the fruit ri...

the effects of rootstocks such as 'sour orange' (citrus aurantium l. var. ‘yerli’), 'carrizo' and 'troyer citranges' (citrus sinensis osb. x poncirus trifoliata raf), 'smooth flat seville sour orange' (citrus spp. hybrid of uncertain origin), 'brazilian sour orange' (citrus aurantiam l. var. ‘brasilian’), 'volkameriana' (citrus volkameriana tan. and pasq.) and 'calamondin' (possibly citrus reti...
