Resumo: Os metais traço são utilizados na indústria e na agricultura e podem estar presentes em efluentes de mineração e esgoto. Assim, esses elementos atingem o ambiente e podem ser prejudiciais aos organismos, meio ambiente e às pessoas. Um monitoramento representativo é essencial para a gestão dos recursos hídricos e consequente prevenção à poluição. Monitoramentos convencionais da água algumas vezes podem não revelar a real condição do ambiente. Isto acontece devido às condições de lançamento e chegada dos poluentes ao sistema, à tecnologia disponível para quantificar a concentração e devido às características da própria substância monitorada. No caso dos metais traço, estes têm uma atração maior por outras partículas (sólidos suspensos, solo, sedimento, carbono orgânico dissolvido), as quais sedimentam, não permanecendo na coluna d'água. Outro fator a ser considerado é que as fontes de metais traço são geralmente intermitentes e as coletas são não contínuas. Além disto, os limites de detecção são altos e não detectam tais elementos na água. Desta forma, o biofilme é uma técnica alternativa de monitoramento, pois analisa o nível de contaminação em um intervalo de tempo. Para este estudo foram construídos dois amostradores. Amostras de biofilme, água e sedimento foram coletadas ao longo de oito meses para dois pontos de monitoramento, um na bacia do rio Barigüi e outro na bacia do rio Miringuava. Parâmetros de qualidade da água, granulometria e conteúdo de metais traço foram estimados. Os resultados mostram que o biofilme identificou os metais traço em praticamente todas as campanhas, enquanto que para as amostras de água isto não aconteceu. As amostras de sedimento representaram a poluição, porém não foi possível determinar o tempo da contaminação pelo método de coleta utilizado. O biofilme representou as diferenças no uso e ocupação do solo, representando poluição consistente com cada bacia hidrográfica. Palavras-chave: biofilme, metais traço, monitoramento, rio Miringuava, rio Barigüi.
Abstract: Trace metals are used in industries and agriculture and can be present in mining and sewer effluents. In such context, these elements can enter the environment and be very harmful to organisms, environment and people. A representative monitoring is essential for water resources management and, consequently, pollution prevention. Conventional water monitoring do not always show real environment condition. That happens because of effluent release conditions, pollution arrival system conditions, available technology to identify element concentrations and monitoring substance characteristics. Specifically for trace elements, they tend to adhere to other particles (suspended matter, soil, sediment, DOC) and deposit in riverbed. Other factor is that trace metal sources are usually from intermittent discharges and collections are not continuous. Besides that, usual techniques have high quantification limit and do not identify these elements in water. Thus, biofilm is an alternative monitoring technique for trace metals evaluation since it analyses contamination level in a time space. For this study, two biofilm samplers were constructed. Biofilm, water and sediment samples were collected for an eight month period in two monitoring sites, Barigüi and Miringuava watershed. Water quality parameters, granulometry, and trace metals content were estimated. Results showed that biofilm identified metals in almost every campaign, while water samples did not. On the other hand, sediment samples represented pollution but it was not possible to determine the contamination time by the used collection method. Biofilm also represented differences in soil use and occupation, representing consistent pollution potential for each basin. Keywords: biofilm, trace metals, monitoring, Miringuava River, Barigüi River.

Texte intégralPartiell nitrifikation i kombination med anammoxprocess, som kallas för deammonifikationprocess, anses vara mer miljövänlig jämfört med konventionell nitrifikation/denitrifikation pga minskat energibehov samt låga utsläpp av CO2 och N2O. Löst syre (DO) är en viktig parameter som påverkar hastigheten för kväverening och aktiviteten hos olika mikroorganismer. DO koncentrationer bör vara på en viss nivå för att ammoniumoxiderande bakterier (AOB) skall producera en tillräcklig mängd NO2-N för anammoxreaktionen, men inte heller för hög då hög NO2-N nivå ger en anammoxhämmande effekt eller ökad tillväxt av nitritoxiderande bakterier (NOB). I denna studie har undersökningar utförts både i laboratorie- och pilotskala för att utvärdera inverkan av olika luftningsstrategier, (som kännetecknas av koncentrationen av löst syre - DO och förhållandet (R) mellan tider för icke luftade och luftade faser), på deammonifikationprocessen i en MBBR (Moving Bed Biofilm Reactor). Tre serier av satsvisa försök utfördes i laboratorieskala med olika syre koncentrationer (2, 3, 4 mg/l) och R värden (0 - kontinuerlig luftning; 1/3, 1, 3 - intermittent luftning), men med samma initiala ammonium-koncentration, volym av den rörliga bädden och temperatur. Man fann att effekten av löst syre (DO) på deammonifikationen var beroende på R-värde. Vid R = 0 och R = 1/3, gav en ökning av löst syre (DO) en signifikant ökning i kvävereningshastigheten, medan för R = 1 och R = 3 observerades samma hastighet i processen oberoende av löst syrehalt (DO). Den högsta hastigheten för kväveavskiljning 3,33 gN/m2.d (avskiljningsgraden var lika med 69,5%) erhölls vid R=1/3 och DO=4 mg/l. Betydligt lägre värden (från 1,17 till 1,58 gN/m2.d) observerades vid R=1 och R=3 för varje undersökt halt av löst syre (DO). Det var en följd av minskad varaktighet av luftad fas och mindre mängd av kvarvarande nitrit i icke luftade faser jämfört med R= 1/3. Pilotskaleförsök utfördes i en MBBR med en arbetsvolym på 200 L. Pilotanläggningen har drivits i 1,5 år med att avlägsna kväve från rejektvatten från avvattning av rötslam. Aktiviteten hos olika grupper av mikroorganismer i biofilmen mättes genom tester av specifik anammoxaktivitet (SAA), syreupptagningshastighet (OUR) och nitratutnyttjandegrad (NUR). Driften var uppdelat i 7 perioder med olika kvävebelastning och luftningsstrategier. Den högsta hastigheten och grad av kväveavskiljning erhölls då DO var 3,5 mg/l och R uppgick till 1/3. Aktivitetstester visade att anammoxbakterier och AOB spelade dominerande roller i biofilmen. De genomsnittliga och maximala värden för specifika anammoxaktiviteten (SAA) var 3,01 gO2/m2.d och 4,3 gO2/m2.d, respektive. 4,0 gO2/m2.d som medelvärde och högsta värde på 5,1 gO2/m2.d erhölls för syreupptagningen för AOB aktivitetstester. Studien visade att användning av en lämpligt vald luftningsstrategi minskar energiförbrukningen utan några negativa effekter på processen. Införande av anaeroba faser och hög kvävetillförseln ökar aktiviteten för anammoxbakterier och NOB-aktiviteten begränsades.

Texte intégralEl trabajo presentado en esta tesis doctoral tiene como principal objetivo la contribución en el campo de la microbiología para entender los biofilms y el posible control de desarrollo mediante el uso de métodos y enfoque multidisciplinar. Los biofilms están definidos como comunidades de microorganismos que crecen embebidos en una matriz exopolisacárida y se adhieren a una superficie inerte o tejido vivo. La formación de los biofilms bacterianos tiene un gran interés en microbiología clínica debido al desarrollo de infecciones que son causadas por contacto directo o por colonización de dispositivos médicos implantados y prótesis. Actualmente se consideran la causa de más del 60 % de las infecciones bacterianas. El problema de los biofilms bacterianos a nivel clínico es que muestran mejor resistencia a antibióticos llegando incluso a ser de 500 a 5000 veces más resistentes a agentes antimicrobianos comparado a la misma bacteria planctónica (bacteria en suspensión). Ha habido muchas tentativas de adaptar métodos a laboratorios clínicos donde se reproducen las condiciones para el desarrollo de biofilms, pero aún no se ha llegado a obtener óptimos protocolos estándar para este propósito de monitorizar la formación y toxicidad en tiempo real. Ha crecido el interés en diseño, desarrollo y utilización de dispositivos de microfluídica que puedan emular los fenómenos biológicos que ocurren con diferentes geometrías, dinámica de fluidos y restricciones de transporte de biomasa en microambientes fisiológicos. La investigación descrita en esta tesis se lleva a cabo con diferentes métodos “label-free” basados en variación acústica y/o propiedades eléctricas para la monitorización de biofilms. El trabajo presentado en esta monografía describe un dispositivo “custom-made” para la utilización de Espectroscopia de impedancia electroquímica como herramienta útil para obtener información de adherencia y formación de biofilms. El hecho de añadir nanopartículas como segundo biosensor permite la correlación de biofilm con su toxicidad en tiempo real para la detección del punto óptimo del tratamiento de biofilms. Finalmente el diseño de esta tecnología es usada para el ensayo de la respuesta de biofilms a antibióticos como modelo in vitro de infecciones causadas por biofilms.
The work presented in this thesis has the main aim to contribute in the field of clinical microbiology to understand the biofilms and the possible of development through the use of methods with multidisciplinary approach. Biofilms are defined as communities of microorganisms that grow embedded in a matrix of exopolysaccharides and adhering to an inert surface or living tissue. The formation of bacterial biofilms has an interest in clinical microbiology with the development of infections that usually arise from either direct contact or the colonization of implanted medical devices and prostheses. Currently they are considered the cause of over 60% of bacterial infections. The problem of bacterial biofilms at clinical level is showing great resistance to antibiotics, so that the biofilm bacteria are 500 to 5000 times more resistant to antimicrobial agents that the same bacteria grown in planktonic cultures (bacteria in suspension). There have been attempts to adapt methods to clinical laboratories where they reproduce the conditions of biofilms, but have not yet adopted an optimal standard protocol for this purpose to follow-up the formation and toxicity in real-time. There has been a growing interest in design, development and utilization of microfluidic devices that can emulate biological phenomena that occur in different geometries, fluid dynamics and mass transport restrictions in physiological microenvironments. The research described in this thesis deals with different label-free methods based on variation of acoustic and electric properties for biofilm monitoring. The work presented in this monograph describe a custom-made device for using electrochemical impedance spectroscopy (EIS) as useful tool to obtain information of adherence and formation of biofilms. The addition of nanoparticles as toxicity biomarker allows the correlation of biofilm formation with its toxicity in real-time for detention of the optimal point for biofilm treatment. Finally the design of this technology is used for testing the biofilm response to antibiotic as in vitro model of biofilm-related infection.
