“…All of these devices have unit magnification, giving an image of the same size as the original object, and no magnifying absolute instrument for homogeneous regions has been known. We proposed a magnifying absolute instrument recently [10] based on a numerically found refractive index with certain special properties, but our colleague Klaus Bering has later shown analytically that such an index in fact does not exist [11].…”

“…For an overall representation of volatile profiles of the bacterial communities, a partial least square‐discriminant analysis was made based on peak areas with 95% confidence regions as described in Tyc et al . (). Identification of metabolites was performed using NIST‐MS Search and accurate mass, retention indices, and spectra match factor using NIST 2014 (National Institute of Standards and Technology, http://www.nist.gov).…”

Summary Competition is a major type of interaction between fungi and bacteria in soil and is also an important factor in suppression of plant diseases caused by soil‐borne fungal pathogens. There is increasing attention for the possible role of volatiles in competitive interactions between bacteria and fungi. However, knowledge on the actual role of bacterial volatiles in interactions with fungi within soil microbial communities is lacking. Here, we examined colonization of sterile agricultural soils by fungi and bacteria from non‐sterile soil inoculums during exposure to volatiles emitted by soil‐derived bacterial communities. We found that colonization of soil by fungi was negatively affected by exposure to volatiles emitted by bacterial communities whereas that of bacteria was barely changed. Furthermore, there were strong effects of bacterial community volatiles on the assembly of fungal soil colonizers. Identification of volatile composition produced by bacterial communities revealed several compounds with known fungistatic activity. Our results are the first to reveal a collective volatile‐mediated antagonism of soil bacteria against fungi. Given the better exploration abilities of filamentous fungi in unsaturated soils, this may be an important strategy for bacteria to defend occupied nutrient patches against invading fungi. Another implication of our research is that bacterial volatiles in soil atmospheres can have a major contribution to soil fungistasis.
