This MiniReview covers the impressive ecological diversity of Bacillus cereus, ranging from a saprophytic life cycle in soil, to symbiotic lifestyles near plant roots and in guts, to various pathogenic ones in diverse insect and mammalian hosts.
Motility is an important trait for some bacteria living in nature and the analyses of it can provide important information on bacterial ecology. While the swimming behavior of peritrichous bacteria such as Escherichia coli has been extensively studied, the monotrichous bacteria such as the soil inhabiting and plant growth promoting bacterium Pseudmonas fluorescens is not very well characterized. Unlike E. coli that is propelled by a left-handed flagella bundle, P. fluorescens SBW25 swims several times faster by rotating a right-handed flagellum. Its swimming pattern is the most sophisticated known so far: it swims forward (run) and backward (backup); it can swiftly ‘turn’ the run directions or ‘reorient’ at run-backup transitions; it can ‘flip’ the cell body continuously or ‘hover’ in the milieu without translocation.
Biological soil crusts (biocrusts) are common to drylands worldwide. The authors employed replicated, spatially nested sampling and 16S rRNA gene sequencing to describe the soil microbial communities in three soils derived from different parent material (sandstone, shale, and gypsum).

Microbial survey of the mummies from the Capuchin Catacombs of Palermo, Italy: biodeterioration risk and contamination of the indoor air
Guadalupe Piñar, Dario Piombino-Mascali, Frank Maixner, Albert Zink, Katja Sterflinger
The Capuchin Catacombs of Palermo contain over 1800 preserved bodies dating from the 16th to 20th centuries AD and showing evidence of biodeterioration. An extensive microbiological and molecular investigation was recently performed. Samples were taken from skin, muscle, hair, bone, stuffing materials, clothes, and surrounding walls as well as from the indoor air. In this study, we witnessed that the different degradation phenomena observed on the variety of materials located at the Capuchin Catacombs of Palermo are biological in origin. Molecular techniques showed the dominance of halophilic species of the domains Bacteria and Archaea on the walls and – as a result of salt emanating from the walls – on the mummies themselves. Nevertheless, specialized microorganisms belonging to taxa well-known for their cellulolytic and proteolytic activities were detected on clothes and stuffing material, and on skin, muscle, hair, and bone, respectively. This specialized microbiota is threatening the conservation of the mummies themselves. Additionally, sequences related to the human skin microbiome and to some pathogenic Bacteria (order Clostridiales) and fungi (genus Phialosimplex) were identified on samples derived from the mummies. Furthermore, a phosphate-reducing fungus, Penicillium radicum, was detected on bone. Finally, the high concentration of airborne fungal spores is not conducive to the conservation of the human remains and is posing a potential health risk for visitors.
Special Virtual Issue - Molecular Insights into Environmental Microbes
New Special Virtual Issue - FEMS Microbiology Ecology meets FEMS Microbiology Reviews
FEMS Microbiology Ecology has compiled a Virtual Issue that cross-links with the May 2013 Thematic Issue of FEMS Microbiology Reviews on Molecular Insights into Environmental Microbes. We have selected key papers from the archives of FEMS Microbiology Ecology to complement the topics of the review articles that reflect on the activity of microbes, ranging from life in symbiosis, commensalism, and syntrophy to life in soil, lakes and oceans.
