The Science of Ultra-Fresh

Test Methods Test Examples Micro-Organisms Definitions Dust Mites Safety

Definitions

Acaricide A substance that kills mites or ticks.**

Antibacterial Referring to an agent or treatment which prevents the growth of bacteria. Can be bactericidal (kills) or bacteriostatic (inhibits growth).

Antifungal Referring to an agent or treatment which prevents the growth of fungi. Can be fungicidal (kills) or fungistatic (inhibits growth).

Antimicrobial A generic term referring to a substance or treatment that inhibits the growth of microorganisms.

Bacteria Simple unicellular organisms that can cause spoilage or odours, as well as infections and health issues.** Bacteria can be classified into 2 basic groups (gram positive and gram negative) based on differences in the structure of their outer cell walls.

Dust Mites Microscopic creatures, related to spiders, which thrive in bedding and carpets, commonly feeding on flakes of shed human skin. Dust mite excretions have been recognized as a significant cause of allergies and asthma.**

Fungi Single or multi-cellular organisms that obtain their nutrients from the breakdown of organic material. Fungi can cause product degradation (rotting), as well as creating stains and odours. Yeasts, molds and mushrooms are all fungi.

Micro-organisms Small or microscopic forms of life, including bacteria, yeasts, fungi, and molds.

Mildew A common name for dark coloured molds which cause disfiguration and degradation. They can be found in interior (i.e. bathrooms) and exterior environments (i.e. tenting, awnings, painted siding).

Molds A widespread group of fungi that are filamentous and reproduce by spore formation. They form hypha and mycelia. Molds are often found on wood, paper, cotton and other natural materials where they can cause degradation.

Virus A genetic element, containing DNA or RNA, which invades biological cells and reproduces using the material of the cell. Viruses are not cells and cannot replicate by themselves. Viruses cannot be controlled by antimicrobials.

Yeasts

A group of fungi which are unicellular and flourish in habitats where sugars are present.
