Direct mobilization of mobilizable plasmids into 91 indigenous bacteria within mixed natural communities has been detected before (Hill et al., 1992; van 92 Elsas et al., 1998), but was never directly quantified. 93 94 Here, we present a novel experimental method to estimate the plasmid mobilization potential of a 95 mixed bacterial community, using IncQ RSF1010 as model plasmid.

50 While several approaches have been developed to measure different kinds of inter-51 microbial interactions, the task of determining the dynamic effect of one microbe’s growth on 52 another remains a challenging task (2, 3, 18–20). Mixed co-cultures, where distinct microbes are 2014-02-10 · The MCM assay measures the rate of plasmid loss in a culture that’s growing without selection at a given temperature. The general idea is that the ARS/CEN plasmid (aka Mini-Chromosome) has a selectable marker, which allows one to measure the proportion of plasmid-bearing cells in a given culture by plating some of the culture on YPD plate and some of the same culture on a dropout plate.

Microbial communities inhabit our entire planet and have a crucial role in biogeochemical processes, agriculture, biotechnology, and human health. Here, we argue that ‘in situ microbiome engineering’ represents a new paradigm of community-scale genetic and microbial engineering. We discuss contemporary applications of this approach to directly add, remove, or modify specific sets of

not certified by peer review) is the author/funder, who has granted bioRxiv a license to display the preprint in perpetuity. 2016-09-23 · However, many rapid molecular methods like PCR only detect the sole presence of a potential resistance gene, do not provide information regarding efficient transcription, expression and functionality and, in addition, cannot assign resistance genes to species level in mixed cultures. By using plasmid-encoded TEM β-lactamase mediated ampicillin plasmids among bacteria under environmentally relevant conditions” and three journal papers (2 submitted and 1 manuscript). Papers comprised in the thesis include: I. Sanin Musovic, Arnaud Dechesne, Jan Sørensen & Barth F. Smets. A novel assay to measure the permissivity of microbial communities towards qualitative potency assays to support pVGI.1(VEGF2) product release. The characterizations of the assays, including specificity of the qualitative assay, and accuracy, precision, linearity and specificity of the quantitative assay are also described.

In five of these streams, we also sampled repeatedly during autumn to test if stereospecific information into quantitative data by means of a novel strategy; typical features of tension wood in hybrid aspen SO NEW PHYTOLOGIST LA English DT soil communities and potentially interact with plant-microbial feedbacks.

Table 5 . Bi- and tri-parental exogenous plasmid isolations from eight bulk soils before and after mercury addition Potential plasmid recipients can stretch across diverse microbial groups , and although transconjugants within sink species may be transient (due to segregation or purifying selection) , their continual replenishment by conjugation from the source means that microbial community richness may be more robust to occasional bouts of selection for plasmid-borne genes.

Novel assay to measure the plasmid mobilizing potential of mixed microbial communities By Barth Smets , Arnaud Dechesne , and Uli Klümper Novel Assay To Assess Permissiveness of a Soil Microbial Community toward Receipt of Mobile Genetic Elements Methods for the robust quantification of bacterial communities are still under development. In this context, the present study aimed to evaluate a method combining competitive PCR (cPCR) and microarray assays for the determination of absolute content of total bacteria and individual bacterial species in samples. Microbial communities inhabit our entire planet and have a crucial role in biogeochemical processes, agriculture, biotechnology, and human health.
