BS 17399:2020 pdf download – Algae and algae products – Terms and definitions
This document defines the terms related to functions, products, and properties of algae and algae products. In order to better pack the methodologies, algae are regarded as a functional group of organisms consisting of microalgae, macroalgae, cyanobacteria and Labyrinthulomycetes.

3 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:

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) [SOURCE: International Energy Agency Bioenergy. Task 42 – Biorefining in a Circular Economy.]
algae oil
glyceridic fraction of lipids derived from algae
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.
amino acid
organic molecule that consist of a basic amino group (−NH 2 ), 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 α-amino [alpha-amino] carboxylic acid. Each molecul contains a central carbon atom, called the α-carbon, to which both an amino and a carboxyl group are attached.
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 sustainability.
energy derived from biomass
NOTE Biomass can be processed into solid, liquid or gaseous fuels or stored energy in biomass can be directly converted into other forms of energy (e.g. heat, light).

liquid fuel for transport produced from biomass
[SOURCE: Directive (EU) 2018/2001 on the promotion of the use of energy from renewable sources]
liquid fuel for energy purposes other than for transport, including electricity and heating and cooling, produced from biomass
[SOURCE: Directive (EU) 2018/2001 on the promotion of the use of energy from renewable sources]
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 2.7]
biomass fuel
gaseous and solid fuels produced from biomass
[SOURCE: Directive (EU) 2018/2001 on the promotion of the use of energy from renewable sources]
biomolecule consisting of Carbon, Hydrogen and Oxygen, characterizable, in a first approximation, by the formula (CH 2 O) n
Note 1 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.
presence of hazardous and/or undesired substances, materials or organisms that can result in physical,chemical and/or biological modifications of properties
photoautotrophic, mixotrophic or heterotrophic prokaryotic organisms, able to obtain energy by using chromophores
deoxyribonucleic acid
polymer of deoxyribonucleotides occurring in a double-stranded (dsDNA) or single-stranded (ssDNA) form
