Rapid quantitative profiling of complex microbial populations
Diverse and complex microbial ecosystems are found in virtually every environment on earth, yet we know very little about their composition and ecology. Comprehensive identification and quantification of the constituents of these microbial communities--a 'census'--is an essential foundation for understanding their biology. To address this problem, we developed, tested and optimized a DNA oligon...
متن کاملEmergence of biodiversity in microbial populations
It is well known that food stress resulting from density-dependent factors affects the mutation rate and hence promotes diversity. It is also known that in bacterial cultures the quality and composition of the growing media conditions the emergence of different spatial patterns. We would like to address the following question: how will the different spatial regions with well defined geometrical...
متن کاملAssessing the genetic structure of microbial populations.
A strenuous debate continues to rage over the use of DNA typing as forensic evidence (1-5). One of the most contentious issues has been how to calculate the probability of a coincidental match between the DNA of a suspect and DNA taken from the scene of a crime (and thought to belong to the perpetrator). In principle, this probability depends upon the genetic structure of the human population, ...
متن کاملFailure of antibiotic treatment in microbial populations.
The tolerance of bacterial populations to biocidal or antibiotic treatment has been well documented in both biofilm and planktonic settings. However, there is still very little known about the mechanisms that produce this tolerance. Evidence that small, non-mutant subpopulations of bacteria are not affected by an antibiotic challenge has been accumulating and provides an attractive explanation ...
متن کاملDynamic modeling of microbial cell populations.
Microbial cultures are comprised of heterogeneous cells that differ according to their size and intracellular concentrations of DNA, proteins and other constituents. Recent advances have been made in cell population modeling, which allow the effects of cell heterogeneity on culture dynamics and metabolite production to be predicted. If the intracellular state can be captured with a few variable...
