By A.N. Rai, B. Bergman, Ulla Rasmussen

Cyanobacterial symbioses are not any longer considered as mere oddities yet as vital parts of the biosphere, happening either in terrestrial and aquatic habitats around the globe. it truly is changing into obvious that they could input into symbiosis with a greater variety of organisms than hitherto identified, and there are numerous extra nonetheless to be came across, rather in marine environments. The chapters conceal cyanobacterial symbioses with crops (algae, bryophytes, Azolla, cycads, Gunnera), cyanobacterial symbioses in marine environments, lichens, Nostoc-Geosiphon (a fungus heavily on the topic of arbuscular mycorrhiza fungi) symbiosis, and synthetic institutions of cyanobacteria with economically very important crops. furthermore, cyanobiont variety, sensing-signalling, and evolutionary elements of the symbiosis are handled. popular specialists actively excited by learn on cyanobacterial symbioses care for ecological, physiological, biochemical, molecular, and utilized points of all identified cyanobacterial symbioses. This quantity on cyanobacteria in symbiosis enhances the 2 past volumes on cyanobacteria released via Kluwer (Molecular Biology of Cyanobacteria, edited via D.A. Bryant and Ecology of Cyanobacteria, edited by means of B.A. Whitton and M. Potts). jointly, the 3 volumes give you the such a lot entire remedy of cyanobacterial literature as an entire. The booklet will function a worthy reference paintings and textual content for educating and examine within the box of plant-microbe interactions and nitrogen fixation.

Microbiological Methods for Assessing Soil Quality (Cabi Publishing)

This e-book presents a range of microbiological equipment that are acceptable or already utilized in local or nationwide soil caliber tracking programmes. an outline is given of techniques to tracking, comparing and handling soil caliber (Part I), via a variety of tools that are defined in adequate element to take advantage of the booklet as a realistic guide within the laboratory (Part II).

Hydrocarbon and Lipid Microbiology Protocols: Activities and Phenotypes

This quantity good points protocols for investigating the hydrocarbon- and lipid-specific actions of microbes. They comprise tools for learning chemotaxis, the colonisation of hydrocarbon surfaces, hydrocarbon uptake, breathing, nitrogen fixation, sulphate relief, membrane stabilisation via cis-trans isomerisation of membrane fatty acids, and the creation of biosurfactants and biopolymers in line with the presence of hydrocarbons.

Antibiotics: Challenges, Mechanisms, Opportunities

A chemocentric view of the molecular buildings of antibiotics, their origins, activities, and significant different types of resistance Antibiotics: demanding situations, Mechanisms, possibilities makes a speciality of antibiotics as small natural molecules, from either average and artificial assets. figuring out the chemical scaffold and useful workforce buildings of the most important sessions of clinically precious antibiotics is necessary to knowing how antibiotics engage selectively with bacterial goals.

Better understanding of partner specificity in Geosiphon with respect to the endosymbiont requires progress in the taxonomy of Nostoc (Mollenhauer and Mollenhauer, 1996), particularly at the molecular level (Paulsrud and Lindblad, 1998; Paulsrud, 2001). 22 KLUGE, MOLLENHAUER, WOLF AND SCHÜßLER 4.

1998). As a whole, some 40 percent of all lichen-forming fungi associate with trebouxioid green algae. These phycobionts are particularly dominant in the in lichen floras of cool and temperate regions. Trentepohlia and related genera (Ulvophyceae) represent another major group of lichen phycobionts. These algae are particularly common in tropical and subtropical lichen floras. , 1998). Coccomyxa is the primary phycobionts of tripartite Nephroma and Peltigera species (Tschermak-Woess, 1988; Vitikainen, 1994; Friedl and Büdel, 1996; Miadlikowska and Lutzoni, 2000).
