Microarrays have unprecedented potential for the high-throughput detection and characterization of uncultivated microorganisms. Several different types of arrays have been developed or adapted for the interrogation of microbial genomes and monitoring microbial population dynamics and/or activity in relation to various microbial processes such as bioremediation and biogeochemical cycling.

Microbial depolymerization processes of exogenous type are studied by modeling and simulation. A mathematical model is transformed to remove a temporal factor of a degradation rate, and an inverse problem is solved numerically to determine the molecular factor using weight distributions with respect to the molecular weight before and after cultivation of a microbial consortium on plyethylene gl...

In Nature microbial populations are subject to fluctuating nutrient levels. Nutrient abundance fluctuations are important for evolutionary and ecological dynamics in microbial communities since they impact growth rates, population sizes and microbial physiology. Here we use automated continuous-culture devices and single-cell imaging to show that when populations of Escherichia coli are subject...

The impact of chemical on the native microbial population during in situ chemical oxidation (ISCO) is not well understood. As a result, some concerns exist within the remediation community as to the potential of negative impacts ISCO may have on bioremediation processes, especially its impact on down-gradient plume control via bioremediation and its impact on subsequent natural attenuation proc...

Arid and semi-arid regions comprise nearly one-fifth of the earth's terrestrial surface. However, the diversities and functions of their soil microbial communities are not well understood, despite microbial ecological importance in driving biogeochemical cycling. Here, we analyzed the geochemistry and microbial communities of the desert soils from Tarim Basin, northwestern China. Our geochemica...

The MIT Faculty has made this article openly available. Please share how this access benefits you. Your story matters. Preface The ocean's biota is numerically dominated by microbial species. Yet the population dynamics, metabolic complexity and synergistic interactions hidden within marine microbial assemblages remain largely uncharted. A full understanding of the living ocean requires moving ...

this paper investigates the importance of considering biomass growth and decay for predicting a field scale microbial degradation of btex plume in an unconfined aquifer system in the pump station area of tehran oil refinery (tor), iran. a two-dimensional finite volume model has been presented to predict multi-species reactive transport incorporating physical, chemical and biological processes i...

Background; Providing Safe drinking water is a prime concerninany community. This analytical study was carried out to evaluate the microbial quality of drinking water in rural areas of northeastern Iran. Methods;The water microbial quality was determined in all villages (a population of 53047 people), in 3 rounds and based on 3 measurements, i.e. Total Coliform, Fecal Coliform, and Heterotro...
