The novel liquid-infused membranes have been shown to mitigate membrane biofouling. Here, the long-term stability of these tested and analyzed using bacterial growth curve models.

Environmental antibiotic risk management requires an understanding of how subinhibitory antibiotic concentrations contribute to the spread of resistance. We develop a simple model of competition between sensitive and resistant bacterial strains to predict the minimum selection concentration (MSC), the lowest level of antibiotic at which resistant bacteria are selected. We present an analytical ...

In the 1960s-1980s, determination of bacterial growth rates was an important tool in microbial genetics, biochemistry, molecular biology, and microbial physiology. The exciting technical developments of the 1990s and the 2000s eclipsed that tool; as a result, many investigators today lack experience with growth rate measurements. Recently, investigators in a number of areas have started to use ...

abstract        typing of bacteria is an important part of epidemiological studies on nosocomial infections. bacterial identification methods have dramatically improved in recent years, which is mainly due to advancements in the field of molecular biotechnology. in many cases, molecular techniques have replaced phenotypic typing methods. currently, a wide range of bacterial typing techniques is...

the present paper examines the mitigating effect of monetary and fiscal policies on the “growth laffer curve” (glc) using a panel data of 38 high income countries over the period 2003-2012. adopting generalised method of moments (gmm) estimators, the paper finds evidence substantiating the presence of an inverted-u glc. moreover, the evidence suggests that the glc shifts downward by employing e...

The Schaechter-Maaløe-Kjeldgaard papers, which have their 50(th) anniversary this year, have major implications for understanding the cell cycle, control of cell growth, control of cell size, metabolic control, the basic bacterial growth curve, and myriad other bacterial and eukaryotic growth phenomena. These ideas have broad applications that should be considered in current studies of the cell...

yeasts, especially saccharomyces cerevisiae, are one of the oldest organisms with broad spectrum of applications, owing to their unique genetics and physiology. yeast extract, i.e. the product of yeast cells, is extensively used as nutritional resource in bacterial culture media. the aim of this study was to develop a simple, rapid and cost benefit process to produce the yeast extract. in this ...

The phenomenon of growth and death of bacteria in ordinary culture media has been studied in considerable detail. The data obtained in such studies show that growth follows a definite course, represented frequently by a curve constructed by plotting the logarithms of the numbers of organisms against time. This logarithmic growth curve has been divided into four main parts: the lag, logarithmic ...
