The electromagnetic wavelength range between 100 nm and 1, including ultraviolet radiation (UV), the visible light spectrum (VIS) and infrared radiation (IR).

Streptococci (sci. classification streptococcaceae) belong to the family of lactic-acid bacteria populating the intestine (like lactobacilli and enterococci) and are Gram-positive, anaerobic but aerotolerant pathogens arranged in chains. Like staphylococci, they exhibit very little UVC resistance.

Extremophilic organism that can grow and reproduce in conditions with a low availability of water. Many mold and yeast species are xerophilic.

Intake or retention of electromagnetic waves by converting wave energy to heat energy.

Adenine (C5H5N5) is one of the four organic complementary bases in DNA and RNA. It forms two hydrogen bonds with thymine in the DNA double-helix.

Chemically, aerobic processes are oxidation reactions. Organisms which require oxygen for metabolism are aerobic; most bacteria and pathogens are aerobic organism.

Amino acids are organic compounds of amine (-NH2) and carboxylic acid (-COOH) with specific side-chains (-R) which join together in long chains to form proteins, neurotransmitters, and transport. Amino acids primarily contain hydrogen, nitrogen, oxygen, and carbon; they form one of the basic building blocks of life.

Amorphous material contains atoms in an irregular shape rather than an ordered structure. An amorphous state is generated via rapid heating or cooling. The opposite of an amorphous structure is a crystalline structure.

Organisms which do not require any oxygen for metabolism are anaerobic organisms; intestinal bacteria for instance are anaerobic organisms.

Aspergillus is a microorganism which belongs to the thermotolerant moulds. Aspergillus niger (black mould), Aspergillus amstelodami and Aspergillus fumigatus are the known members of this genus. They grow best at high temperature, and a number of these aspergillus species form metabolic products that are toxic for humans (mycotoxins) by causing foo [..]
