Aquatic biofilms : ecology, water quality and wastewater by Anna M. Romani, Helena Guasch, M. Dolors Balaguer

By Anna M. Romani, Helena Guasch, M. Dolors Balaguer

Biofilms in aquatic ecosystems colonize a number of surfaces (sand, rocks, leaves) and play a key function within the atmosphere. Aquatic biofilms offer strength and natural subject to the foodstuff chain, they're very important in recycling natural subject, and so they give a contribution to water caliber. This e-book is a concise assessment of the present wisdom on aquatic biofilms, with an emphasis at the features and ecology of biofilms in typical ecosystems, in addition to a spotlight on biofilm purposes associated with water pollutants difficulties. The booklet is split into 3 sections: "Biofilms Mode of Life," "Biofilms and Pollution," and "New applied sciences utilizing Biofilms." within the first part, the aquatic biofilm mode of lifestyles is defined and reviewed. Key features coated contain the third-dimensional constitution and cell-to-cell verbal exchange of biofilms, their dynamic prokaryotic variety, and their important position in biogeochemical cycles. this is often by way of a accomplished examine using biofilms in water caliber. extra chapters speak about environmental hazard evaluate, tracking, and ecotoxicological techniques. extra issues comprise biofilm improvement in sewage pipes and the possibility of microbial changes in those platforms. the ultimate part specializes in vital examples of novel applied sciences in keeping with biofilms for water therapy, together with the biodegradation of toxins, the applying of bioelectrogenic biofilms, and the biofilm skill for nitrogen removing.

Comparative Genomics: Using Fungi as Models (Topics in Current Genetics)

Fungal comparative genomics began in 2000 by way of the genome sequencing of numerous yeast species. on the grounds that then, over 30 fungal genome sequences became on hand. This set represents a tremendous evolutionary divergence, but in addition includes heavily comparable genomes. This quantity describes how one can use this set of genomes to track occasions in genome evolution, to extract information regarding hugely conserved and not more conserved series components, and to enhance novel equipment in genomics.

Bacterial Pangenomics: Methods and Protocols

Bacterial genomics is a mature learn interdisciplinary box, that is approached by means of ecologists, geneticists, bacteriologists, molecular biologists and evolutionary biologists operating in clinical, commercial and easy technology. because of the massive diffusion of bacterial genome research, Bacterial Pangenomics: equipment and Protocols is ready to give you the newest methodologies concerning the examine of bacterial pangenomes via masking the 3 significant components: the experimental tools for drawing close bacterial pangenomics, the bio informatic pipelines for research and annotation of series information and eventually the tools for inferring useful and evolutionary good points from the pangenome.

Aquatic biofilms : ecology, water quality and wastewater treatment

Biofilms in aquatic ecosystems colonize quite a few surfaces (sand, rocks, leaves) and play a key position within the surroundings. Aquatic biofilms offer power and natural topic to the nutrients chain, they're vital in recycling natural topic, they usually give a contribution to water caliber. This ebook is a concise evaluation of the present wisdom on aquatic biofilms, with an emphasis at the features and ecology of biofilms in average ecosystems, in addition to a spotlight on biofilm purposes associated with water pollutants difficulties.

The focus in this chapter will be on river/lotic biofilm systems. In this respect the following philosophical statement might be important: ‘you cannot step twice into the same river’ (Heraclitus 535–475 bc). Thus heterogeneity, sampling, reproducibility and comparison represent critical issues in fluvial biofilm research. As a result, river biofilms remained for a long time a neglected field in microbiological research (Leff, 1994). , 2003) and the use of model systems (Lawrence and Neu, 2003) for the study of biofilm composition and microstructure.
