| With growing concern about the protection of soil quality and biodiversity many countries have established regional and national programmes to monitor soil quality. This book reviews the theory and practice of a range of the various microbiological methods used within these programmes. The first section gives an overview of approaches to monitoring, evaluating and managing soil quality. The second section provides a practical handbook with detailed descriptions of the methods. The methods are described in chapters on soil microbial biomass and numbers, soil microbial activity, soil microbial diversity and community composition, and plant-microbe interactions and soil quality. Finally, a census is given of the main methods used in over 30 European... |

| PathOrganic assesses risks associated with the consumption of fresh and minimally processed vegetables due to the prevalence of bacterial human pathogens (e.g. Salmonella enterica, pathogenic E. coli, Campylobacter spp., Listeria monocytogenes) in organically grown plant produce. The project aims at evaluating whether organic production poses a risk on food safety and addresses the food chain by taking into consideration potential sources of pathogen transmission (e.g. animal manure). In addition, it evaluates whether organic production may reduce the risk of pathogen manifestation. From a European perspective, vegetable-linked outbreaks are not well investigated. Within the PathOrganic project, surveys of organically grown vegetables are carried out in... |

| Soil microbiological analyses may serve as a means for assessing soil characteristics. Standard microbiological culture-techniques, however, leave over 90% of the microorganisms in the environment unaccounted for. Several more recently developed analytical techniques such as DNA, phospholipid fatty acid (PLFA), and community level substrate utilization (CLSU) Ængerprints allow for more detailed analyses of soil microbial communities. We applied analyses of (1) community DNA with PCR and restriction fragment length polymorphism (RFLP), (2) community PLFAs with gas chromatography and mass spectrometry, and (3) CLSU with Biologe gram-negative-plates, to evaluate the biological characteristics of three soils used in pesticide degradation studies. Each of these... |

| PathOrganic assesses risks associated with the consumption of fresh and minimally processed vegetables due to the prevalence of bacterial human pathogens in plant produce. The project evaluates whether organic production poses a risk on food safety, taking into consideration sources of pathogen transmission (e.g. animal manure). The project also explores whether organic versus conventional production practices may reduce the risk of pathogen manifestation. In Europe, vegetable-linked outbreaks are not well investigated. A conceptual model together with novel sampling strategies and specifically adjusted methods provides the basis for large-scale surveys of organically grown plant produce in five European countries. Critical control points are... |
