Whois & Analysis for molekule.com

Bacteria (common noun bacteria, singular bacterium) constitute a large domain of prokaryotic microorganisms.

Typically a few micrometres in length, bacteria have a number of shapes, ranging from spheres to rods and spirals.

Bacteria were among the first life forms to appear on Earth, and are present in most of its habitats.

Bacteria inhabit soil, water, acidic hot springs, radioactive waste, and the deep portions of Earth's crust.

Bacteria also live in symbiotic and parasitic relationships with plants and animals.

Most bacteria have not been characterised, and only about half of the bacterial phyla have species that can be grown in the laboratory.

The study of bacteria is known as bacteriology, a branch of microbiology.

A virus is a small infectious agent that replicates only inside the living cells of other organisms.

Viruses can infect all types of life forms, from animals and plants to microorganisms, including bacteria and archaea.

A mold or mould is a fungus that grows in the form of multicellular filaments called hyphae.

In contrast, fungi that can adopt a single-celled growth habit are called yeasts.

Volatile organic compounds (VOCs) are organic chemicals that have a high vapor pressure at ordinary room temperature.

Their high vapor pressure results from a low boiling point, which causes large numbers of molecules to evaporate or sublimate from the liquid or solid form of the compound and enter the surrounding air, a trait known as volatility.

For example, formaldehyde, which evaporates from paint, has a boiling point of only –19 °C (–2 °F).

An air purifier or air cleaner is a device which removes contaminants from the air in a room.

These devices are commonly marketed as being beneficial to allergy sufferers and asthmatics, and at reducing or eliminating second-hand tobacco smoke.

The commercially graded air purifiers are manufactured as either small stand-alone units or larger units that can be affixed to an air handler unit (AHU) or to an HVAC unit found in the medical, industrial, and commercial industries.

Air purifiers may also be used in industry to remove impurities such as CO2 from air before processing.

Pressure swing adsorbers or other adsorption techniques are typically used for this.
