Microbes, with their vast metabolic capabilities and great adaptability, occupy almost every conceivable ecological niche on Earth. Thus, could they survive in the oligotrophic (i.e., nutrient poor) deionized (DI) water that we use for experiments? Observations...

Zeta potential, defined as the electric charge at the shear plane, is widely used as a proxy parameter for bacterial cell surface charge. Nonspecific adsorption of ions or polyelectrolytes onto the cell surface, however, alters the value and polarity of the measured...

Solid medium enables spatially resolved simultaneous cultivation of different microbes in a simple and relatively low cost format useful for preliminary screening of microbial diversity. Lack of color contrast between colonies and agar, however, hampers colony...

The characteristics of the culture vessel determine, to a large extent, the type of growth medium suitable for use. For example, most growth media for high cell density cultivation are designed for expensive bioreactors operating either in continuous or fed-batch...

Sufficient quantities of cells of consistent characteristics are needed for studying biologicalprocesses (at the population level ) in many areas of applied microbiology. However, generating the requisite biomass by cell culture is usually the rate-limiting step...

Influenza A viruses cause an annual highly contagious respiratory disease in humans, and are responsible for periodic human pandemics that have high mortality rates. Pandemic influenza A viruses can result from reassortment of one or more gene segments between...

DNA extracted from feces (human and bovine) and water samples was used for the massive pyrosequencing of the hypervariable V3 region of the 16S rRNA gene, revealing 4296 operational taxonomic units (OTUs). The greatest diversity was observed in samples of cattle...

Marine microbes experience varying degrees of barometric pressure depending on the depth at which they reside. High barometric pressure can create an extreme environment which favors the survival of barophilic and barotolerant bacteria. This paper aims to quantify...

The genetic structure of bacterial populations can be related to geographical locations of isolation. In some species, there is a strong correlation between geographical distance and genetic distance, which can be caused by different evolutionary mechanisms. Patterns...

Antibiotic-resistant bacteria complicate many infections and can be difficult to eradicate from hospitals. The population dynamics and ecology of these organisms in the hospital setting, however, is not well understood. Here, we report extensive strain-based antagonistic...

Much of Earth’s biodiversity is at the mercy of currents and physical turnover. Residence time (τ) is the average time that particles spend in a system and is estimated from the ratio of volume to flow rate. Here, we present a framework for how τ influences biodiversity...

Biodiversity generally affects ecosystem processes, but to what extent detailed knowledge about specific aspects of biodiversity helps us understand and predict specific ecosystem functions is not well-known. We hypothesised that information about functional gene...
