Interactions between a genetically marked Pseudomonas fluorescens strain and bacteriophage ΦR2f in soil: Effects of nutrients, alginate encapsulation, and the wheat rhizosphere
TL;DR: Experiments in which host cells and phage ΦR2f were introduced into two soils of different texture revealed that host cells were primarily lysed in the presence of added nutrients, and phages reached highest titres in these nutrient-amended soils.
Natural transformation of Acinetobacter sp. strain BD413 with cell lysates of Acinetobacter sp., Pseudomonas fluorescens, and Burkholderia cepacia in soil microcosms.
TL;DR: There seems to be a clear difference between the physical and the functional significance of chromosomal DNA in soil, where fractions have been found to persist for several weeks in soil.
Universal and species-specific bacterial 'fungiphiles' in the mycospheres of different basidiomycetous fungi.
TL;DR: PCR-DGGE analyses showed clear effects of the mycosphere of diverse fungi on the total bacterial and Pseudomonas communities in comparison with those in the corresponding bulk soil.
Risks associated with the application of genetically modified microorganisms in terrestrial ecosystems
TL;DR: A flow scheme is presented containing key processes controlling bacterial fate and thus putative risk, and it is suggested that the fate of the GEMMO has to be investigated at first in contained microcosms mimicking the environment in comparison to the wild-type organism.
Survival of Pseudomonas fluorescens and Bacillus subtilis introduced into two soils of different texture in field microplots
TL;DR: Antibiotic-resistant strains of Pseudomonas fluorescens and Bacillus subtilis, produced by transposon Tn5 mutagenesis and transformation with plasmid pFT30, respectively, were characterized and the antibiotic resistance remained stable for over 50 generations without selective pressure.
