BS/EN 17399-2020 pdf download.Algae and algae products – Terms and definitions.
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminological databases for use In standardization at the following addresses:
• IEC Electropedia: available at http:/Jwww.elcctropedia.orgJ
• ISO Online browsing platform: available at https://www.iso.orgJobp
3.1
algae biorefinery
facility that integrates algae biomass conversion processes and equipment to produce a spectrum of bio-based products (food, feed, chemicals, materials) and bioenergy (biofuels, power and/or heat)
ESOURCE: International Energy Agency Bioenergy. Task 42 – Biorefining In a Circular Economy.I
3.2
algae oil
glyceridic fraction of lipids derived From algae
3.3
algae strain
population of unicellular/pluricellular organisms of a single algae species, all descended from the entirety/or a part of an organism or several organisms, being synonymous with a monoclonal culture and a genetic representative of a single algae species
NOTE This definition includes sexual and asexual reproduction.
3.4
amino acid
organic molecule that consist of a basic amino group (—NH2), an acidic carboxyl group (—COOH), and an organic R group (or side chain) that is unique to each amino acid
NOTE In this context the term amino acid is short for a-amino laipha-aminol carboxylic acid. Each molecule contains a central carbon atom, called the a-carbon, to which both an amino and a carboxyl group are attached.
3.5
artificial light
photons from a source other than the sun
EXAMPLE fluorescent light and LEDs
Note 1 to entry: The energy to produce light could come from a mix of sources that can range from fossil fuels, nuclear plants and renewable and sustainable sources, such as wind. photovoltaics. biomass, etc.
Note 2 to entry: Energy consumed and emissions associated with this should be accounted for in the assessment of the sustalnability.
liquid fuel for energy purposes other than for transport, including electricity and heating and cooling, produced from biomass
ISOURCE: Directive (EU) 2018/2001 on the promotion of the use of energy from renewable sources]
3.9
biomass
material of biological origin excluding material embedded in geological formations and/or fossilized
EXAMPLE (Whole or parts of) plants, trees, algae, marine organisms, microorganisms, animals, etc. [SOURCE: EN 16575:2014, definition 2.71
3.10
biomass fuel
gaseous and solid fuels produced from biornass
[SOURCE: Directive (EU) 2018/2001 on the promotion of the use of energy from renewable sourcesj
3.11
carbohydrate
biomolecule consisting of Carbon, Hydrogen and Oxygen, characterizable, in a first approximation, by the formula (CH2O)
Note I to entry: They include sugars, oligo and polysaccharides as well as polyols derived.
Note 2 to entry: Gross composition”: carbohydrates, lipids, polyols and proteins plus ashes should sum as close as possible to 100 % dry weight of algae biomass as a raw material for food, feed and other applications.
3.12
contamination
presence of hazardous and/or undesired substances, materials or organisms that can result in physical, chemical and/or biological modifications of properties
3.13
cya nobacteria
photoautotrophic, mixotrophic or heterotrophic prokaryotic organisms, able to obtain energy by using chromophores
3.14
deoxyribonucleic acid
DNA
polymer of deoxyribonucleotides occurring in a double-stranded (dsDNA) or single-stranded (ssDNA) form
[SOURCE: EN ISO 22174:2005, definition 3.1.2]
3.17
eukaryotes
organisms with a cell structure in which the nucleus is surrounded by a nuclear membrane
[SOURCE: ISO 6107-8:1993, definition 18]
3.18
fouling
non-target organisms either on the surface or within algal biomass (epiphytes or endophytes), including macroalgae, microalgae, bacteria, cyanobacteria, fungi. or animals, including harmless organisms and pathogens
NOTE This also includes such organisms within production systems not directly associated with target organisms, but associated with tanks, ropes/nets, bioreactors and all cultivation surfaces: potentially compromising quality and value including purity and safety of target algal growth
3.19
genus
principal taxonomic category that ranks above species and below family
NOTE When using taxonomy to name an organism, the genus is used to determine the first part of its two-part name (genus and species)
3.20
heterotrophy
metabolism that utilizes organic compounds as energy and carbon source
NOTE Light is not required as an energy source.
3.21
Identification
process for determining that an isolate belongs to one of the established taxa
[SOURCE: EN ISO 22174:2005, definition 3.1.9]
3.22
labyrinthulomycetes
labyrinthulea
class of protists or chromista that produce a network of filaments or tubes and includes the family Thraustochytriaceae
3.23
lipids
class of natural organic substances characterized by very low water solubility, high organic solvents solubility, high carbon and hydrogen content, biosynthesized for energy storage and/or metabolic and structural functions.BS/EN 17399-2020 pdf download.
