Bacteria (Agriculture)

Microscopic organisms having round, rod-like, spiral or filamentous single-celled or noncellular bodies often gathered into colonies.

Bacteria (Beauty)

A group of single cell microorganisms that can cause disease by producing poisons that are harmful to human cells. The undamaged skin has natural substances that prevent bacteria from entering living tissues. Synthetic cosmetic materials can deplete these substances.

Bacteria (Beer Brewing)

Single-celled organisms which are generally undesirable in beer. Bacterial contamination can result in sour, musty, or vegetable-like flavors in beer, and can cause bottles to gush when opened, or (in extreme cases) even explode. Fortunately, most bacteria do not like hops, alcohol, or low pH -- all of which are present in finished beer. Certain unusual styles of beer (e.g. Lambic, Oud Bruin, Berlineer Weisse) actually rely on bacterial fermentation for their unique tart character.

Bacteria (Cancer)

One-cell organisms, some of which can cause disease. They are found in soil, air and water and also in the tissues of humans, plants and animals.

Bacteria (Carpet)

Any of numerous widely distributed unicellular micro-organisms exhibiting both plant and animal characteristics, and ranging from harmless and beneficial to those that cause disease. Extremely small (.4-10 microns), single-cell microscopic organisms. They are the most numerous organisms on earth and are formed everywhere, especially in soil. Because they are microscopic they are easily airborne, and they are carried in water as spores are some of the most resistant forms of life known. Bacteria reproduce at an astounding rate given proper growth conditions (food source, moisture, temperature). Most are saprophytic (feed on non-living organisms), though many are parasitic (feed on living organisms). In water damage situations, the by-product of bacterial growth is the characteristic “sour” odor associated with initial stages of damage, and later, bacteria are responsible for the musty odor associated with mildew. Most bacteria (and their odors) are killed or controlled with extreme heat and sunlight (ultraviolet), or by such chemicals as alcohol, chlorine, ammonium chlorides, and others.

Bacteria (Culinary)

Single celled micro-organisms (plural)

Bacteria (Dairy Production)

Single-cell organisms living either independently or in close association with other living organisms. Often referred to as microbes or microorganisms because of their microscopic size. Some bacteria are beneficial, but others cause infectious diseases.

Bacteria (Developmental Psychology)

Tiny creatures making up a division (Bacteria) of microorganisms that are typically one-celled, have no chlorophyll, multiply by simple division, and can be seen only with a microscope: They occur in three main forms, spherical (cocci), rod-shaped (bacilli), and spiral (spirilla); some bacteria cause diseases such as pneumonia and anthrax, and others are necessary for fermentation, nitrogen fixation, and so on.

Bacteria (Ecology)

Microscopic organisms from the Moneran Kingdom. Some bacteria are very helpful and others carry harmful diseases.

Bacteria (Environment)

(Singular

Bacteria (Evolution)

Tiny, single-celled, prokaryotic organisms that can survive in a wide variety of environments. Some cause serious infectious diseases in humans, other animals, and plants.

Bacteria (Female Health)

Tiny one-celled creatures that reproduce by splitting in half

Bacteria (Food Industry)

Bacteria are a large group of single celled microscopic life forms whose genetic material (D.N.A.) is not bound within a membrane or stabilised by special proteins (known as histones).
See microbes.

Bacteria (Food Irradiation)

One-celled microorganism that can cause illness and spoil food, sometimes without changing the food's taste, smell, or appearance.

Bacteria (Food Preservation)

A large group of one-celled microorganisms widely
distributed in nature. See MICROORGANISM.

Bacteria (Food Safety)

Tiny, one-celled microorganisms found in the environment. Bacteria multiply rapidly in food under the right conditions, and some bacteria can cause foodborne illness. Helpful bacteria can be used to make yogurt, vinegar and some cheeses.

Bacteria (Forestry)

Typically one-celled microorganisms which have no chlorophyll, multiply by simple division, and can be seen only with a microscope

Bacteria (Genetics)

Tiny one-celled organisms.

Bacteria (Genetics and Food)

Large group of single celled micro-organisms which lack an organised central nucleus. Bacteria are everywhere — in soils, water, air, and on or in the tissues of plants and animals. They play an important role in global ecology, promoting chemical changes such as decay and nitrogen cycling (the processes by which nitrogen and its compounds move through the environment and in living organisms). They can have a beneficial or deleterious effects on their host.

Bacteria (Health and Beauty)

A group of single cell microorganisms that can cause disease by producing poisons that are harmful to human cells. The undamaged skin has natural substances that prevent bacteria from entering living tissues. Synthetic cosmetic materials can deplete these substances.

Bacteria (Hepatitis C)

Any of various one-celled microorganisms of the plant kingdom, existing as free- living organisms or as parasites of other organisms. Bacteria reproduce through subdivision, and are classified according to their shape and behavior.

Bacteria (Human Body)

a group of microscopic, single-cell organisms that lack a nucleus. Bacteria inhabit almost all environments, including organic matter, soil, water and the bodies of animals. Some are harmful to humans, others are beneficial. Bacteria are the chief cause of infectious diseases in humans.

Bacteria (Huntingtons Disease)

A small, single-celled living organism that has DNA and can replicate its own DNA without the help of a host cell. Some bacteria are helpful to humans, such as those that live in our stomach and help with digestion, while some are harmful, releasing toxins or poisonous waste products.

Bacteria (Immunization)

Tiny one-celled organisms present throughout the environment that require a microscope to be seen. While not all bacteria are harmful, some cause disease. Examples of bacterial disease include diphtheria, pertussis, tetanus, Haemophilus influenza and pneumococcus (pneumonia).

Bacteria (Incontinence)

Microscopic organisms that can cause infection and are usually treated with antibiotics.

Bacteria (Microbiology)

All prokaryotes that are not members of the domain Archaea.

Bacteria (Nutrition)

A single-celled very tiny organism. Some bacteria can cause disease; other "friendly" bacteria are normally present in the body and perform such useful functions as aiding digestion and protecting the body from harmful invading organisms.

Bacteria (Pests)

Bacteria are germs which are so small that they can only be seen through a microscope. They come in various shapes (spherical, rod-shaped, and spiral shaped) and sizes (length ranges from 0.5 to 50 mm.

Bacteria (Physical Geography)

Simple single celled prokaryotic organisms. Many different species of bacteria exist. Some species of bacteria can be pathogenic causing disease in larger more complex organisms. Many species of bacteria play a major role in the cycling of nutrients in ecosystems through aerobic and anaerobic decomposition. Finally, some species form symbiotic relationships with more complex organisms and help these life forms survive in the environment by fixing atmospheric nitrogen.

Bacteria (Planetary Science)

Single-celled microorganisms whose cells lack a nucleus. Bacteria comprise a major domain of life called prokaryotes. In contrast, the cells in eukaryotes have a well-defined nucleus; eukarya include molds, plants, and animals. Another major domain is called archaea, microorganisms with genetic features distinct from prokarya and eukarya. Most methane-producing bacteria are actually archaea, but for simplicity many biologists informally refer to all non-eukaryotes as "bacteria."

Bacteria (Pool and Spa)

Single-celled, microorganisms. Can vary from harmless to pathogenic and include such types as E. Coli and pseudomonas aeruginosa. Bacterial growth is the direct result of inadequate sanitation and is affected by such factors as bather load, pool or spa cleanliness, water temperature, water chemistry and filtration.

Bacteria (Sanitation)

A group of universally distributed, rigid, essentially unicellular microscopic organisms lacking chlorophyll. They perform a variety of biological treatment processes including biological oxidation, sludge digestion, nitrification, and denitrification.

Bacteria (Science)

Single-celled organisms that have no membrane around the DNA of their cells (no nucleus)

Bacteria (Sexually Transmitted Diseases)

Bacteria are one kind of microscopic (too small to see) germ. Many types of bacteria can make people sick or cause infections. Bacteria live in water, dirt, plants, animals or humans. Humans naturally have some in their body already. Humans can also get some from other people when they have unprotected sex. These kinds of BACTERIA can make people sick. There are medicines called ANTIBIOTICS that kill BACTERIA. Bacteria cause some sexually transmitted diseases, for example, chlamyida, gonorrhea, syphilis and "trich."

Bacteria (Speleological)

Unicellular microscopic plants. They are autotrophs, ie make their own food. They sometimes form aggregations. Very important in caves as decomposers causing high CO2 levels seen in some caves. Probably play a role in most speleogenesis.
Biology - Flora & Fauna.

Bacteria (Women's Health)

Microorganisms that can cause infections.

Bacteria (Womens Health)

Microorganisms that can cause infections.
