(Terminology)Standard Terminology Relating to Bioenergy and Industrial Chemicals from Biomass
Standard Terminology Relating to Bioenergy and Industrial Chemicals from Biomass
SCOPE
1.1 This document is composed of terms, definitions of terms, descriptions of terms, and acronyms used in ASTM documents related to the field of bioenergy and industrial chemicals from biomass. Terms that are adequately defined in a general dictionary are not defined in this terminology standard.
1.2 This standard includes terminology used in areas related to bioenergy and industrial chemicals from biomass, such as, but not limited to: characterization and identification of biomass, aseptic sampling, preservation of biological samples, sustainability, denatured fuel ethanol, cooking fuels and biomass conversion.
1.2.1 The bylaws for Committee E48 allow the definitions approved in current E48 standards to be added to this terminology standard editorially. The definitions will have an attribution to indicate the standard(s) containing the definition. Subcommittee E48.91 can also develop definitions for the terminology standard. Those definitions will be attributed to the subcommittee.
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

3. Terminology
3.1 Definitions:
aerobic—able to live, grow, or take place only where free oxygen is present. E1126
aerobic fermentation—fermentation processes that require the presence of air. E1126
anaerobic—living or active in an airless environment. E1126
anaerobic bacteria—microbes whose metabolisms require the absence of free oxygen. E1126
anaerobic digester—a chemical reactor in which anaerobic bacteria are used to decompose biomass or organic wastes to
produce methane and carbon dioxide. E1126
anaerobic digestion—degradation of organic matter by microbes in the absence of air (oxygen) to produce methane and carbon
dioxide (biogas). E1126
anaerobic fermentation—fermentation processes conducted in the absence of air. The following anaerobic fermentation
processes are significant in obtaining useful forms of energy from biomass: (1) alcoholic fermentation, fermentation processes
whereby certain microorganisms convert glucose and other substrates with alcohol as an end product, (2 ) methane fermentation,
generally termed anaerobic digestion (See also anaerobic
