TL;DR: In this article, the metal ion adsorption was found to increase with the speed of agitation and at an optimum pH value of between 4 and 7, where the metal ions sequestered can be released in an acid solution until the concentration of these metal ions reaches a level where conventional methods can be used to provide economic metal recovery and potential revenue generation.

TL;DR: In this article, the presence of sulfate-reducing bacteria in sampled water mains, in a region that would otherwise be expected to be stable, both by direct sampling, by using coupons in a Robbins device installed in the distribution network, and by sampling from laboratory tanks.

TL;DR: Aquabacterium commune, a member of the beta proteobacteria family that is a recently isolated, predominant member of various European drinking water distribution system biofilms, was selected as a test organism in this article.

TL;DR: In this article, the authors used X-ray diffraction analysis to investigate evidence of in situ biogenic clay formation occurring in experiments set up to simulate microbial-geochemical interactions in deep subsurface low-nutrient granitic environments.

TL;DR: Perkins, W.T., Hartley, S., Pearce, N.G., Dinelli, E., Edyvean, R., Sandlands, L.J. as mentioned in this paper used dealginated seaweed in the BIOMAN project.

TL;DR: The use of SOC method is suggested as a time saving and lower cost biomass concentration measurement and the accuracy and costs are compared.
