ecological success  n.

p. 402

The ecological success of cyanobacteria is unmatched. Consider Prochlorococcus marinus, a member of the marine phytoplankton and arguably the most abundant photosynthetic organism on our planet.

electrogenic sulfide oxidation  n.

p. 571

This coupled metabolic process happens so fast that it can only be explained if the microbes move the electrons generated from hydrogen sulfide oxidation as electrical currents along the filaments. For this reason, the process is referred to as electrogenic sulfide oxidation.

electromicrobiology  n.

p. 761

With the development of diverse processes that exploit microbial electricity, a new field in microbiology called electromicrobiology has emerged.

endemic cholera  n.

p. 724

Explain why endemic cholera primarily affects children, whereas both children and adults were vulnerable in Haiti and to infection by O139 V. Cholerae.

endergonic  adj.

p. 139

The xdeltamxG is positive if the reaction consumes energy (endergonic) and negative if it releases energy (exergonic).

endogenous retrovirus sequence  n.

p. 497

Surprisingly, humans and other animals carry in their genomes a profusion of so-called endogenous retrovirus sequences.

endolysin  n.

p. 480

Another viral protein accumulates in the cytoplasm (endolysin) and gains access to the periplasm once the holin pores form.

endosymbiotic nitrogen  n.

p. 382

Endosymbiotic nitrogen fixers

El context és en una taula.

endosymbiotic theory  n.

p. 590

These organelles were once bacteria that found their way inside another cell and evolved together (the endosymbiotic theory).

energy-coupled transport  n.

p. 174

For example, the large vitamin B12 (cobalamin) molecule is transported across the outer membrane by energy-coupled transport.

Enterobacter asburiae YT1  [nom científic]

p. 579

They isolated two strains from the biofilms, Enterobacter asburiae YT1 and Bacillus sp. YP1.

entry mechanism  n.

p. 473

To enter the host cell, the viral membrane first has to fuse with the host cell membrane, a feat carried out by the proteins of the envelope that recognize specific receptor of the host cell membrane and induce the fusion of the viral envelope (Fig. 17.8). Not all enveloped viruses use this entry mechanism.

environmental trigger  n.

p. 375

Two of the major environmental triggers of sporulation are the near depletion of nutrients and sufficient cell density.

enzymatic regulation  n.

p. 186

Enzymatic regulation. One critical feature of biosynthetic pathways is not depicted in our metabolic map (Fig. 7.13).

epibiont  n.

p. 529

The metabolic exchange from the cyanobacteria to the bacterial epibionts is beautifully revealed!

epidemic cholera  n.

p. 723

Why was Haiti vulnerable to epidemic cholera?

epigenetic regulation  n.

p. 705

The HSV strategy is something entirely different: epigenetic regulation. This term refers to any process that not only turns genes on or off in one cell, but also maintains the pattern of gene expression in its daughter cells, without changing the DNA code (hence epi, meaning "near to" or "on top of" -genetics).

EPS  n. (exopolysaccharide)

p. 257

Many bacteria make their cell envelope even more complex by surrounding it with a slippery coat assembled from a variety of extracellular polysaccharide materials or exopolysaccharides (EPSs; chapter 2).

Epsilonbacterium  [nom científic]

p. 405

The Epsilonbacteria include microaerophilic species such as Helicobacter pylori, the causative agent of stomach ulcers.

eukaryotic genetic exchange  n.

p. 208

Note how different eukaryotic genetic exchange is in this respect: when eukaryotic gametes fuse, their complete set of chromosomes mix.

evolutionary consequence  n.

p. 506

Evolutionary consequences. Phages have strongly affected bacterial evolution, possibly on a large scale.

exopolysaccharide  n. (EPS)

p. 257

Many bacteria make their cell envelope even more complex by surrounding it with a slippery coat assembled from a variety of extracellular polysaccharide materials or exopolysaccharides (EPSs; chapter 2).

external structure  n.

p. 26

This chapter and the next deal with structures of prokaryotic cells, focusing first on the external structure (this chapter) and then on the interior structure of the cell (chapter 3).

extracellular electron transfer  n.

p. 603

Some microbes have evolved complex electron transport chains that allow them to transfer electrons outside the cell, a process known as extracellular electron transfer.

extraterrestrial life  n.

p. 370

Endospores are highly resistant to extremes of temperature, radiation, reactive oxygen, acid, and alkali, Indeed, they are the most resistant of all known biological structures. For this reason, endospores readly enter into conversations about extraterrestrial life.
