Biogenic Sulphuric Acid Attack in Sewage Systemst organism. The cell counts correlated with the extent of corrosion. As a result of the study the particular ecosystem designated the ‘Biogenic’ Sulphuric Acid Corrosion of Concrete’ was reproduced in a simulation apparatus. Samples were inoculated with thiobacilli and incubated for 9 months in a te

Screening for Biocides to Inhibit Biogenic Sulphuric Acid Corrosion in Sewage Pipelines. and .. Biocides A and B were effective at concentrations of less than 0·001%. Tests with heterotrophic microorganisms resulted in minimal inhibitory concentrations, which were at least ten times higher. Concrete blocks were treated with two concentrations of A and B (lOg/cm ., 30g/cm .. The blocks

Clinical Consequences of Microbial Action on Medicinesinically significant. These changes can include the biodegradation of formulation excipients leading to an alteration in the physicochemical characteristics of a product, or metabolism of the drug itself. Such drug transformations, while infrequently found in contaminated pharmaceutical products, ar

Der Kriminalitätsbegriff in der Wissenschafts. It is shown that the knowledge of the mechanisms of activity of antimicrobials as well as of the structure and functioning of the various species of microbes allows the tailoring of microbicides which are adapted to the intended use and the species of microbes to be combatted.
