Optimization of the PMI method

L.I. van Vliet (Student)

In this report, the further optimization of the PMI method is investigated and the possibility to act as an alternative method for the Chemical Oxygen Demand (COD) in wastewater is discussed. In this study the oxidation efficiency of the PMI method is improved by optimizing the oxidation time, concentration …

Impact of industrial wastewater treatment plants on surface water quality

F. van den Hurk (Student); A.P. van Wezel (Begeleider); Anne Oele (Begeleider)

Direct emissions of emerging and well known contaminants via industrial wastewater treatment plants (IWTPs) considerably impact Dutch surface water concentrations with vulnerable drinking water functions. In this nationwide impact study, the impact of 182 Dutch IWTPs was modelled, whilst taking geographic …

Corrosion of mild steel and stainless steel in aqueous environment

Ajmal Kamal (Student); R. van der Meulen

Mild steel is the main material of alloys in use. Approximately 20% of corrosion damage of metals is induced by bio corrosion. The aim of this research was to study the corrosion performance of mild steel and stainless steel when immersed in natural seawater. In order to verify the effect of the microorganisms …

Cross-linking of starch with bifunctional precursors of nitroalkenes

Heeres, André (Biobased Ingredients And Materials); Van Doren, Henk A.; Gotlieb, Kees F.; Kellogg, R. M.; Bleeker, Ido Pieter

Granular starch was cross-linked with 1,3-di-O-acetyl-2-nitro-1,3-propanediol (1), 1,3-di-O-pivaloyl-2-nitro-1,3-propanediol (2), 2-nitro-3-O-pivaloyl-1-propene-3-ol (3), 1,3-di-O-acetyl-aci-2-nitro-1,3-propanediol (4), 1,3-di-O-pivaloyl-aci-2-nitro-1,3-propanediol (5) and 1,6-di-O-acetyl-2,5-dinitro-1,6-hexanediol …

Isolation of Alcaligenes sp strain L6 at low oxygen concentrations and degradation of 3-chlorobenzoate via a pathway not involving (chloro)catechols

Krooneman, Janneke (Bioconversion And Fermentation Technology); Wieringa, E.B A; Moore, E.R B; Gerritse, J; Prins, R.A; Gottschal, J.C

Isolations of 3-chlorobenzoate (3CBA)-degrading aerobic bacteria under reduced O-2, partial pressures yielded organisms which metabolized 3CBA via the gentisate or the protocatechuate pathway rather than via the catechol route. The 3CBA metabolism of one of these isolates, L6, which,vas identified as …

Transient repression of the synthesis of OmpF and aspartate transcarbamoylase in Escherichia K12 as a response to pollutant stress

Faber, Folkert (Life Sciences & Renewable Energy); Egli, Thomas; Harder, Wim

The synthesis of total cellular proteins in Escherichia coli K12 was studied in batch culture following exposure of cells to low concentrations of monochlorophenol, pentachlorophenol and cadmium chloride. Changes in protein patterns were identified after pulse-chase labelling of proteins with [35S]methionine …
