Journal of Environmental Sciences 2017年第6期29卷 230-239页

In order to reduce the level of transmission of diseases caused by bacteria and fungi, the development of antimicrobial additives for use in personal care, hygiene products, clothing and others has increased. Many of these additives are based on metals such as silver and titanium. The disposal of these products in the environment has raised concerns pertaining to their potential harmfulness for beneficial organisms. The objective of this study was to evaluate the influence of the shape, surface chemistry, size and carrier of three additives containing silver and one with titanium dioxide （TiQ） on microcmstacean survival. Daphnia ruagna was used as a bioindicator for acute exposure test in suspensions from 0.0001 to 10,000 ppm. Cefiodaphnia dubia was used for chronic test in Ti02 suspensions from 0.001 to 100 ppm, D. magna populations presented high susceptibihty to all silver based additives, with 100% mortahty after 24 hr of exposure. A different result was found in the acute experiments containing TiO2 suspensions, with mortality rates only after 48 hr of incubation. Even on acute and chronic tests, Ti02 did not reach a hnear concentration-response uersus mortality, with 1 ppm being more toxic than 10,000 ppm on acute test and 0.001 more toxic than 0.01 ppm on chronic assay. Silver based material toxicity was attributed to silver itself, and had no relation to either form （nano or ion） or carrier （silica, phosphate glass or bentonite）. Ti02 demonstrated to have a low acute toxicity against D. magna.

The Occurrence of Bacteria of the Genus Aeromonas *** Oreochromis niloticus(Tilapia)and in the Water of Amateur Sport Fish Ponds and Sensitiveness to Antimicrobials

引用

Food and Nutrition Sciences 2019年第1期10卷 81-97页

作者： adriana Dos Santos Silva Ludmilla santana Soares E.Barros Danuza Das Virgens Lima Daniela Simoes Velame Universidade Federal do Reconcavo da Bahia(UFRB) Cruz das AlmasBrazil

Since amateur fishing in fishponds has been on the increase in Brazil, there is a great concern on the microbiological quality of fish. One hundred and thirty-eight samples were collected during the dry and rainy periods in ten fish farms. Aeromonas spp. counts and tests for sensitiveness to antimicrobials were performed, coupled to the physical and chemical analyses of water. Tests revealed that 70% of samples were contaminated by Aeromonas spp., with water averaging 2.92 Log CFU/100 mL during the rainy period and 3.16 Log CFU/100 mL during the dry one. Fish contaminated by Aeromonas spp. averaged 2.58 Log CFU/100 mL during the rainy period and 3.53 Log CFU/100 mL during the dry one. Aeromonas spp. samples were multi-resistant to 2 or 8 antimicrobials in 62.5% of the samples. Ampicillin was the antimicrobial with the highest resistance percentage rate. Results showed that fish bred in amateur fish farms constituted a health risk for the population.

Transesterification of sunflower oil in microchannels with circular obstructions

Chinese Journal of Chemical Engineering 2018年第4期26卷 852-863页

作者： Harrson S.santana Joao L.Silva Jr Deborah S.Tortola Osvaldir P.Taranto School of Chemical Engineering University of Campinas13083-852 CampinasSPBrazil Federal Institute of Education Science and Technology of South of Minas Gerais-IFSULDEMINAS37560-260 Poaso AlegreMGBrazil

The present paper studied numerical and experimentally the transesterification reaction between sunflower oil and ethanol with NaO H catalyst in microchannels with circular obstructions. The micromixer design influence on fluid mixing and oil conversion was investigated for a range of operating conditions: Reynolds number(Re = 0.1–100),Temperature(25–75 °C), ethanol/oil molar ratio(6-12), and catalyst concentration(0.75 wt%–1.25 wt%), using three microchannel configurations(Length = 35 mm; Width = 1500 μm; Height = 200 μm): T-shape – channel without obstructions; MCO – channel with 3 obstructions ensemble – equally disposed over longitudinal length;MWO – channel with 7 obstructions ensemble. The MCO micromixer was based on literature work, and the MWO is a totally new micromixer design. Experimental tests were conducted in similar conditions in microreactors using these micromixers(Length = 411 mm) made of polydimethylsiloxane. The MCO configuration presented the highest performance(mixing index of 0.80 at Re = 100), oil conversion of 81.13% at 75 °C, molar ratio of 9 and catalyst concentration of 1%. Experimental results showed high conversions for MCO and MWO configurations(99.99%) at 50 °C, molar ratio of 9 and catalyst concentration of 1%, with a residence time of 12 s.
