METHANOGENIC [6 records]

Record 1 2016-05-24

English

Subject field(s)
  • Microbiology and Parasitology
  • Biochemistry
  • Biomass Energy
DEF

Microorganisms capable of producing methane.

CONT

The third group involves diverse species of methanogenic bacteria which utilize the H2 and CO2 and acetate for growth and production of the final products, CH4 and CO2.

French

Domaine(s)
  • Microbiologie et parasitologie
  • Biochimie
  • Énergie de la biomasse
CONT

Les bactéries méthanogènes. Elles nécessitent l'action préalable des deux premiers groupes [les bactéries acidogènes et fermentatives] car elles transforment H2, CO2 et acétate pour produire les composés gazeux CO2 et CH4.

Record 2 2016-02-25

English

Subject field(s)
  • Biochemistry
  • Civil Engineering
CONT

At any given temperature enough time(minimum digester tank volume) must be provided to allow the methanogenic bacteria to process the organic material properly.

French

Domaine(s)
  • Biochimie
  • Génie civil
DEF

Grand récipient dans lequel on procède à la fermentation d'une matière organique.

Record 3 2015-03-11

English

Subject field(s)
  • Waste Management
CONT

The anaerobic bacteria used are commonly a mixture of methanogenic bacteria that use methane as their main source of carbon; these bacteria are found in anaerobic sediment or digester sludge.

OBS

The term "sludge" is considered to be an uncountable noun. However, it is often found in the plural form (sludges), particularly when speaking of different types of sludge.

Key term(s)
  • digester sludges

French

Domaine(s)
  • Gestion des déchets
CONT

Les bactéries anaérobies sont communément un mélange de bactéries méthaniques qui utilisent le méthane comme source principale de carbone; elles se retrouvent dans les sédiments anaérobies et dans les boues des digesteurs.

Key term(s)
  • boue de digesteur

Spanish

Record 4 2003-01-16

English

Subject field(s)
  • Microbiology and Parasitology
CONT

The third group involves diverse species of methanogenic bacteria which utilize the H2 and CO2 and acetate for growth and production of the final products, CH4 and CO2.

CONT

Estimates are also difficult because of the complexity of methanogenic food chains which implies large spatial and temporal variations of the CH4 emission rates within individual exosystems.

French

Domaine(s)
  • Microbiologie et parasitologie
DEF

Qui produit du méthane.

OBS

L'épithète «méthanogène» n'est pas attesté dans les dictionnaires généraux. Les termes «méthanisant» et «méthanigène» ont été suggérés sans grand succès.

Record 5 2000-11-08

English

Subject field(s)
  • Biological Sciences
DEF

An anaerobic digester in which the acidogenic(acid-forming) reactions are separated from the methanogenic reactions.

French

Domaine(s)
  • Sciences biologiques
DEF

Type de digesteur en continu qui permet de séparer la phase acidogène et méthanogène dans 2 digesteurs distincts.

Spanish

Record 6 1981-03-20

English

Subject field(s)
  • Biochemistry
CONT

The acid forming stage involved the fermentative bacteria which hydrolyse polymers and ferment the products to organic acids, alcohols, CO2 and H2. The methane-forming stage involved the methanogenic bacteria as such which catabolized the products of the fil stage with production of the final products, CH4 and CO2.

French

Domaine(s)
  • Biochimie
CONT

Longtemps, on a découpé le déroulement de la fermentation anaérobie en deux phases: - la phase acide ou acidogénèse; - la phase méthanique ou méthanogénèse.
