Welcome to the MME-Group

The main objective of our research is to evaluate the extent of genetic flow within
the natural microbial communities and the responses to environmental perturbations. State-of-the art techniques form the basis of our research and teaching.

Anvendelse af gfp-reportergener

Vi har indsat gfp-genet i kromosomet på Kluyvera sp., som også har et plasmid, som hæmmer gfp’s fluorescens. Derfor er det kun celler uden dette plasmid, der lyser grønt. De grønt-fluorescerende områder er således en plasmid-fri underpopulation af celler. Link

Use of the green fluorescent protein (gfp) reporter gene in studies of the effect of conjugative transfer on plasmid stability

Colony of Kluyvera sp. MB101 chromosomally marked with gfp and containing plasmids encoding a repressor of gfp-expression. This results in gfp-expression only in cells having lost the plasmid. Green fluorescing patches represent plasmid-free segregant cells. Link

The mystery of black stains on the walls of cognac distelleries

In the March issue of Microbe News Magasin of ASM, 2009 Bernhard Dixon described the work of James Scott and collegues, Toronto.
Widespread black areas on walls and roofs of cognac and armagnac distelleries in France and elsewhere are caused by a microfungus, Baudoinia compniacensis (described as Torula). The fungus is only found in that special environment and is able to utilize ethanol as carbon source and endure high temperatures. Pre-adaption to heat and ethanol induce formation of putative heat shock proteins.
The fungus has also been found in Denmark, at a roof of the Cherry Heering factory in Dalby and was isolated and described as Torula compniacensis (Kjøller 1961), which is one of the two only published registrations since the original description in 1881!
