Bacteria are one-celled organisms that lack a nucleus defined by a nuclear membrane and the organelles that are associated with eukaryotic cells. Bacteria are prokaryotes that maintain their genetic material, DNA, in a long circular molecule. Bacteria...

Infectious diseases depend on the interplay between the ability of pathogens to invade and/or proliferate in the body and the degree to which the body is able to resist. If the ability of a microorganism to invade, proliferate and cause damage in the...

Bacteria have been designed to be adaptable. Their surrounding layers and the genetic information for these and other structures associated with a bacterium are capable of alteration. Some alterations are reversible, disappearing when the particular...

It was inevitable that sooner or later we would ask bacteria to make electricity. I mean, what else do they do but hang around in staggering, colossal numbers, doing pretty much nothing but eating, wiggling, and reproducing. Why not ask them to put...

Researchers at the Pennsylvania State University in Middletown, Pa., have demonstrated that a combination of ultraviolet light and metal-oxide coatings can deliver an environmentally friendly approach to keeping glass surfaces clean of biocontamination. "Ultraviolet light has been used for years to disinfect water,"...

Scientists say a new bacteria species discovered in Yellowstone's thermal pools could improve the use of bacteria to produce ethanol.Researchers found the bacteria in Octopus and Mushroom springs as well as in Green Finger Pool. The bacteria thrive in hot water, growing best between 120...

The microorganisms that live in your gut could explain one of the sources of obesity, says a new study from researchers at Washington University. Bacteria live throughout the body, but some intestinal bacteria appear to be better than others at...

The growth rate of Bacillus Megaterium and how different lightings effect its growth rate.

Bacterial transformation is what happens when a bacterial cell accepts outside DNA and incorporates it into its own DNA, something that generally happens with plasmids. To this end, an experiment took place in which E. coli bacteria was transformed with FlouroGreen in order to test the hypothesis that the transformed bacteria will glow and grow on an Ampicillin plate.

Bacteria consist of only a single cell, but don't let their small size and seeming simplicity fool you.
