Academic literature on the topic 'Bacteria-protozoa interactions'

This chapter reviews current advances regarding plant–microbe interactions in aquatic Utricularia. New findings on the composition and function of trap commensals, based mainly on the advances in molecular methods, are presented in the context of the ecological role of Utricularia-associated microorganisms. Bacteria, fungi, algae, and protozoa colonize the Utricularia trap lumen and form diverse, interactive communities. The involvement of these microbial food webs in the regeneration of nutrients from complex organic matter is explained and their potential contribution to the nutrient acquisi

The book ends with a chapter devoted to discussing interactions between microbes and higher plants and animals. Symbiosis is sometimes used to describe all interactions, even negative ones, between organisms in persistent, close contact. This chapter focuses on interactions that benefit both partners (mutualism), or one partner while being neutral to the other (commensalism). Microbes are essential to the health and ecology of vertebrates, including Homo sapiens. Microbial cells outnumber human cells on our bodies, aiding in digestion and warding off pathogens. In consortia similar to the anae

Processes in Microbial Ecology discusses the major processes carried out by viruses, bacteria, fungi, protozoa, and other protists—the microbes—in freshwater, marine, and terrestrial ecosystems. The book shows how advances in genomic and other molecular approaches have uncovered the incredible diversity of microbes in natural environments and unraveled complex biogeochemical processes carried out by uncultivated bacteria, archaea, and fungi. The microbes and biogeochemical processes are affected by ecological interactions, including competition for limiting nutrients, viral lysis, and predatio

The soil is a repository of microorganisms such as bacteria, fungi, algae, and protozoa. Among these, more bacteria are found, most of which are located in the rhizosphere region of the soil. The rhizosphere, under the direct control of plant root secretions, is the complex, narrow area of the soil. It is densely populated with microorganisms (mostly bacteria) that interact with the plants. These interactions influence the growth of the plant directly or indirectly. Plant growth-promoting rhizobacteria (PGPR) inhabiting the rhizosphere colonizes the plant roots and increases plant growth via different mechanisms. Iron is an essential micronutrient required by almost all life forms including plants. Oxidation of Fe2+ (soluble) to Fe3+ (insoluble) due to the soil's aerobic conditions limits its bioavailability. Siderophores are selective low molecular weight ferric ion chelators secreted by bacteria to acquire iron from the surrounding. They bind to iron (Fe3+) with high specificity as well as high affinity. By helping the insolubilisation of iron, it promotes the growth and yield.
