“…Bolster et al, 2006, Jacobs et al, 2007, who reported that hydrophobicity and zeta potential play an important role in bacteria transport, but consistent with our previous observations (Lutterodt et al, 2009a and observations made by Bolster et al (2009Bolster et al ( , 2010, our results demonstrated that there was no statistically significant correlation between measured cell properties (zeta potential, motility, cell size, cell aggregation, and hydrophobicity) and transport parameters ( f , ω and s k and (C/C 0 ) max ). Bolster et al (2010) explained that additional confounding factors may be present when correlating E. coli transport to surface properties.…”

“…In addition, r-values along transport distance were low, and did not show any pattern. These observations are in contrast to those of van Loosdrecht et al (1987a, b) and Jacobs et al (2007). On the other hand, the observed non-dependence of cell hydrophobicity on attachment was in agreement with the findings of Gannon et al (1991).…”

Groundwater contamination by faecal matterAccording to the WHO, an estimated one billion people lack access to an improved water supply and two million deaths per year are attributable to unsafe drinking water, sanitation and hygiene. In addition, many countries still report cholera to the WHO (WHO, 2004). Groundwater may be an important source of water for safe drinking and industrial water supplies, however, many water borne disease outbreaks are known to have been caused by the consumption of groundwater contaminated by pathogenic microorganisms (Goss et al., 1998;Macler and Merkle, 2000;Bhattacharjee et al., 2002;Close et al., 2006;Powell et al., 2003). Pathogenic microorganisms find their way into the sub-surface through the spreading of sewerage sludge on fields, leakage from waste disposal sites and landfills (Taylor et al., 2004), infiltration from cesspits, septic tank infiltration beds, and pit latrines (Foppen ...

“…The theory indicates that biofilm adhesion decreases with increasing DE TOT 132 values (Azeredo et al 1999;Liu and Zhao 2005;Jacobs et al 2007;Bayoudh et al 2009;Hori and Matsumoto 2010). However, little work on the influence of surface energy components on DE TOT 132 or biofouling adhesion has been reported.…”

The interaction energy between bacteria and substrata with different surface energies was modelled by the extended DLVO (Derjaguin, Landau, Verwey and Overbeek) theory. The modeling results revealed that the interaction energy has a strong correlation with the CQ (Chen and Qi) ratio, which is defined as the ratio of the Lifshitz-van der Waals (LW) apolar to the electron donor surface energy components of substrata. Both modeling and experimental results with different bacteria including P. fluorescens, Cobetia marina and Vibrio alginolyticus demonstrated that if the LW surface energy of bacteria is larger than that of water, which is the case for most bacteria, the number of adhered bacteria decreases with a decreasing CQ ratio while bacterial removal rate increases with a decreasing CQ ratio. However, if the LW surface energy of bacteria is less than that of water, the opposite results are obtained. The CQ ratio gives a clear direction for the design of anti-biofouling and biofouling-release coatings through surface modification.

“…51 Em meios aquosos, as forças de interação polares devem-se principalmente a interações entre doadores e receptores de elétrons que representam interações do tipo ácido-base de Lewis, que são geralmente designadas por AB. 52 As interações interfaciais são relevantes para a definição de hidrofobicidade e hidrofilicidade. A diferença básica entre hidrofobicidade e hidrofilicidade é a competição entre a energia livre interfacial de coesão do sólido, imerso na água, e a energia livre de coesão do líquido.…”

Recebido em 17/11/09; aceito em 21/4/10; publicado na web em 1/9/10 COLLOIDAL ASPECTS OF BACTERIAL ADHESION. The ability of bacteria to attach to surface and develop into a biofilm has been of considerable interest to food industry. Electrostatic, Lifhistz-van der Waals and Lewis acid-base forces are usually considered responsible for the interactions at the interface of the bacterial adhesion. The study of microbial adhesion thermodynamic is important because it represents the reflection of microbial surface and food processing surface physicochemical characteristics. This review examines the most important aspects involved in bacterial attachment to a surface with emphases in thermodynamics of adhesion process.Keywords: bacterial adhesion; biofilm; microbial surface thermodynamics. INTRODUÇÃOA adesão bacteriana é importante em um grande número de processos tecnológicos, envolvendo desde a microbiologia médica e patológica, passando pela indústria de alimentos e engenharia de meio ambiente até a área de ciência de biomateriais. 1A adesão de micro-organismos a superfícies é um fenômeno que ocorre naturalmente em meios aquosos e depende das propriedades superficiais (tensão superficial, entalpia superficial por unidade de área, composição da superfície, etc.) das interfaces dos suportes de adesão (aço, polímeros, mármore, etc.) e das membranas dos micro-organismos. Além disso, as propriedades microbiológicas e as características do meio circundante, tais como temperatura, pH, força iônica e disponibilidade de nutrientes, determinam, em muitos sistemas, o processo de adsorção. 1 A formação de um biofilme inclui muitas etapas, mas um pré-requisito é a adesão das células microbianas à superfície. Estudos recentes das propriedades de adesão de bactérias têm mostrado que, em alguns casos, as características físico-químicas da superfície da célula contribuem determinantemente no processo de adesão. 2A adesão e a formação de biofilmes microbianos podem ser indesejáveis, sob diversos aspectos, em várias áreas de aplicação. A presença do biofilme em dispositivos médicos implantados já foi descrita em lentes de contato, cateteres venosos centrais, tubos endotraqueais, dispositivos intrauterinos, válvulas cardíacas mecânicas, marcapassos, cateteres de diálise peritoneal, próteses articulares, tubos de timpanostomia, cateteres urinários e de derivação ventrículo-peritoneal.3 Na indús tria de alimentos, a adesão e a formação de biofilme podem tornar o pro cesso de cloração da água menos eficiente; 4 reduzir a eficiência de transferência de energia na forma de calor em trocadores térmicos; diminuir o fluxo em tubulações; desencadear processos corrosivos e, principalmente, se tornarem fon tes de contaminação microbiana.5 Sob o aspecto microbiológico, a adesão pode constituir-se de mi cro-organismos alteradores e/ou patogênicos, que resultam em sérios problemas de higiene, de saúde pública ou de ordem econômica. 6 Por outro lado, em alguns casos, o processo de adesão ou biofilme pode ser desejável, a exemplo daqueles existentes ...
