The design of “Super E. coli” through automated reaction network generation and genome scale models

Vassily Hatzimanikatis, Noushin Hadadi, Keng Cher Soh

Genome-scale metabolic reconstructions capture the known metabolic capabilities of organisms and their analysis have provided many insights into complex biochemical networks. However, this approach relies on a database of known biochemical reactions and he ...

Plastidic type I signal peptidase 1 is a redox-dependent thylakoidal processing peptidase

Jieping Zhu

Thylakoids are the photosynthetic membranes in chloroplasts and cyanobacteria. The aqueous phase inside the thylakoid known as the thylakoid lumen plays an essential role in the photosynthetic electron transport. The presence and significance of thiol-disu ...

A Novel Approach to Design of Metabolic Engineering Strategiesa

Vassily Hatzimanikatis, Ljubisa Miskovic, Meriç Ataman, Georgios Fengos, Keng Cher Soh, Anirikh Chakrabarti

Dynamic nonlinear models of metabolism offer significant advantages as compared to traditional steady-state counterparts for the analysis of metabolic networks and identification of metabolic engineering strategies. Uncertainties in the metabolic network s ...

Monitoring the post-irradiation E. coli survival patterns in environmental water matrices: Implications in handling solar disinfected wastewater

César Pulgarin, Stefanos Giannakis, Ana Isabel Merino Gamo

In this study, simulated solar disinfection of secondary effluent was followed by dark storage at different temperatures or different receiving water matrices. Escherichia coli illumination was followed by 3-day monitoring of the bacterial population and i ...

Ammonium formate decomposition over Au/TiO2: a unique case of preferential selectivity against NH3 oxidation

Oliver Kröcher

The unique selectivity of Au/TiO2 for converting ammonium formate to CO2 in the presence of excess O2 and H2O without oxidising NH3 up to 300 °C is reported. The catalyst is highly stable and selective even after severe hydrothermal aging. ...

On the unfounded enthusiasm for soft selective sweeps

Jeffrey David Jensen

Underlying any understanding of the mode, tempo and relative importance of the adaptive process in the evolution of natural populations is the notion of whether adaptation is mutation limited. Two very different population genetic models have recently been ...

Single microbe trap and release in sub-microfluidics

Andreas Vasdekis

Life on Earth is comprised mostly of microbes with significant implications in disease and carbon cycling. However, their dimensions and mobility make microbes challenging to analyse on-chip. A sub-micron resolution microfluidic system (sub-microfluidics) ...

An experimental model approach of biologically-assisted silicate dissolution with olivine and Escherichia coli - Impact on chemical weathering of mafic rocks and atmospheric CO2 drawdown

Philippe Gillet, Bruno Garcia

Chemical weathering of Mg, Ca-silicates and alumino-silicates contributes significantly to the drawdown of atmospheric CO2 over long time scales. The present work focuses on how this mode of weathering may change in the presence of free-living bacteria in ...

Design and construction of a portable whole-cell living bacterial biosensor for the detection of arsenic in water

Nina Buffi

Contamination of drinking water with arsenic is a recurring problem in both industrialized and developing countries. Supplies for large populations can have concentrations much higher than the permissible levels, set by the World Health Organization (WHO) ...

Rapid detection of bacterial resistance to antibiotics using AFM cantilevers as nanomechanical sensors

Giovanni Dietler, Sandor Kasas, Giovanni Longo, Livan Bladimir Alonso Sarduy, Laura Rio Marques, Justin Terence Notz Pekkanen

The widespread misuse of drugs has increased the number of multiresistant bacteria1, and this means that tools that can rapidly detect and characterize bacterial response to antibiotics are much needed in the management of infections. Various techniques, s ...
