Atividade da enzima peroxidase em frutos de mamão (Carica papaya) submetidos a tratamentos físicos pós-colheita. Repositório Alice
ADABO, G.; TERAO, D.; HALFELD-VIEIRA, B. de A.; NECHET, K. de L..
Resumo: Este trabalho teve como objetivo determinar a atividade de peroxidases em frutos de mamão submetidos aos tratamentos físicos em pós-colheita, hidrotérmico e ozônio, aplicados individualmente e combinados, durante 8 dias de armazenamento. Um lote de 102 frutos de mamão do grupo Solo, proveniente de uma lavoura comercial, sem tratamento na pós-colheita, foi submetido aos tratamentos hidrotérmico (70ºC/15s), ozônio (1,5 ppm), aplicados tanto individualmente quanto combinados. Frutos não submetidos aos tratamentos físicos configuraram como controle. Após os tratamentos, os frutos foram mantidos durante 7 dias em câmara fria (10 ± 2ºC e 80 ± 2% de umidade relativa) e 1 dia em condição ambiente (23 ± 2ºC). Para a determinação da atividade de peroxidases,...

Ozone treatment of textile wastewater relevant to toxic effect elimination in marine environment OceanDocs
Guendy, H.R..
Ozone is a powerful oxidizing agent. The reaction of ozone with organic compounds in aqueous media has achieved a variety of treatment goals. The advantage of ozonation over the other oxidants is that the degradable products of ozonation are generally non-toxic, its final products are CO2 and H2O, and also the residual O3 in the system changes in few minutes to O2 .Convential treatment of textile wastewater includes various combinations of biological (activated sludge), physical and chemical processes. The dyestuffs existed in these wastewater are highly structured organic molecules which are hardly break down biologically. Decolorization of two types of dyes, Direct Pink 3B and Reactive Violet SH- 2R, by ozonation in aqueous medium was studied in presence...

Viral depuration of Mytilus galloprovincialis in ozone treated water ArchiMer
Croci, L; Demedici, D; Franco, E; Gabrielli, R; Dipasquale, S; Toti, L.
The depuration effectiveness of Poliovirus 1 and HAV contamined mussels, when subjected to flowing ozonized water, was evaluated. Mussels were experimentally contamined and then depurated up to 72 hours using a pilot depuration system with ozone treated and untreated water. The results showed that viral infectivity titter decreased more rapidly in mussels subjected to ozonized water (from 10 super(4) TCID50 to 10 super(1.5) TCID50 per ml of Poliovirus 1 but in the following period it remained unchanged. Also HAV was detected in the mussels after 72 h of depuration.

การลดเชื้อ Campylobacter jejuni ในซากไก่ด้วยคลอรีนและโอโซน Thai Agricultural
Panrapee Iamtaeweejarloen; Pravate Tuitemwong; Jirawat Kantakrienwong; Kooranee Tuitemwong.
Objectives of this study were to investigate the process sensitivity to Campylobacter spp. and to assess the reduction efficiency of ozonation and chlorination in chilling step of the poultry process using data derived from mCCDA plating and SimPlate MPN methods. Samples of 80 were collected from 4 process steps in the processing plant (scalding, plucking, inside outside washing, and chilling). Numbers of Campylobacter spp. on mCCDA at the respective steps were 3.35, 3.20, 2.68 and 0.20 logCFU/ml, while the SimPlate MPN had 2.54, 2.48, 2.31 and 0.84 log CFU/ml, respectively. Chilling is the most sensitive process to reduce the number of bacteria on both media. Chlorination at 1.5 ppm reduced Campylobacter spp. by 97.46% and 58.62% on mCCDA and SimPlate...
