Enteric fermentation was the second largest anthropogenic source of methane emissions in the United States from 2000 through 2009. [7] In 2007, methane emissions from enteric fermentation were 2.3% of net greenhouse gases produced in the United States at 139 teragrams of carbon dioxide equivalents (Tg CO 2) out of a total net emission of 6087.5 Tg CO 2.

Enteric fermentation occurs in the gut of some animals, especially ruminants. In the rumen , anaerobic organisms, including methanogens, digest cellulose into forms nutritious to the animal. Without these microorganisms, animals such as cattle would not be able to consume grasses.
Animal agriculture is a similarly large source (30%); primarily because of enteric fermentation by ruminant livestock such as cattle and sheep. According to the Global Methane Assessment published in 2021, methane emissions from livestock (including cattle) are the largest sources of agricultural emissions worldwide [ 10 ] A single cow can make ...
Enterobacter taylorae is a Gram-negative bacteria formerly known as Enteric Group 19, and also known as Enterobacter cancerogenus. [1] Strains of E. taylorae are positive for: Voges-Proskauer, citrate utilization, arginine dihydrolase and malonate utilization. They ferment D-glucose and also ferment D-mannitol, L-rhamnose and cellobiose.
The genus Hafnia is one of more than 40 genera that currently comprise the order Enterobacterales.. Although Møller originally described this genus in 1954, the legitimacy of this group was constantly challenged over the next two decades, often being referred to by synonyms such as "Enterobacter alvei", "Enterobacter aerogenes subsp. hafniae" and "Enterobacter hafniae" but it is mostly ...
It is designed to selectively isolate gram-negative and enteric (normally found in the intestinal tract) bacteria and differentiate them based on lactose fermentation. [1] Lactose fermenters turn red or pink on MacConkey agar, and nonfermenters do not change color.
This culture media is important in medical laboratories by allowing the identification of enteric bacteria microbes in a short period of time. [4] Rapid lactose fermentation produces acids, which lower the pH. This encourages dye absorption by the colonies, which are now colored purple-black.
Fermentation is used to produce the heme protein found in the Impossible Burger. Fermentation can be used to make alternative protein sources. It is commonly used to modify existing protein foods, including plant-based ones such as soy, into more flavorful forms such as tempeh and fermented tofu.
