Antimicrobial Producing Bacteria as Agents of Microbial Population Dynamics
… interest for drug discovery. We examined the antimicrobial "Red Soils" of the Hashemite Kingdom of Jordan that have historically been used to prevent infection and cure rashes by the native peoples. Antimicrobial producing bacteria were present in these soils and found to be the reason for their …

Long-Term Quantitative Microscopy: From Microbial Population Dynamics to Growth of Plant Roots
… a digital holographic microscope for measuring microbial population dynamics. It allows three dimensional localization of hundreds of cells within a mm³ sized volume, at micron resolution and an acquisition period of minutes. The technique is simple and inexpensive, which enabled us to construct …

Population oscillations, synchronization, and range expansion in a bacterial cross-protection mutualism
Cooperation between microbes can enable microbial communities to survive in harsh environments. Enzymatic deactivation of antibiotics is a cooperative behavior that can allow resistant cells to protect sensitive cells from antibiotics. The prevalence of this mechanism of antibiotic resistance in …

Performance of Floating Biofiltration in Methane Oxidation
… climate change. Biofiltration, which relies on microbial oxidation, has emerged as a sustainable and effective method for mitigating methane emissions. This study introduces a novel floating biofiltration system designed to enhance methane removal directly from the surface of waste lagoons using …

An Investigation of the Biochemistry of Biological Phosphorus Removal
… understanding of the biochemical mechanisms and microbial population dynamics that determine the reliability and efficiency of EBPR, and the utilization of this information to improve the design and operation of BNR plants. Such knowledge will also contribute to better structure of modeling tools …

In vitro examination of the effect of orlistat on the ability of the faecal microbiota to utilize dietary lipids
… DGGE were used to monitor changes in bacterial populations. Bacteria were cultivated from the GMM only (control) systems at SS. All strains isolated were screened for lipolytic activity using tributyrin agar. FISH and DGGE demonstrated that none of the compounds (singly or in combination) added …

Microbial community dynamics in denitrifying biofilters receiving agricultural drainage
… environmental and management factors affect the microbial communities responsible for biofilter functional. To do so, we employed two different approaches. First, in our spatial study we sampled one biofilter over the course of an afternoon in 2007 to determine how total and denitrifying …

Development and application of a microbial reliability model to analyze denitrifying biofilter stability
… tile drainage flow through a woodchip bed, where microbial activity converts influent nitrate to nitrogen gases. As with many engineered ecosystems, performance stability of the biofilters is of concern. While much research has focused on stability concepts in ecology, there is no consensus on the …
