Hace 6 horas · The microorganisms used in sulfide processing (Table 2) belong exclusively to archaea and bacteria (both prokaryotes), while metal extraction from non-sulfidic materials may involve also eukaryotes (described in Sects. 5 and 6).Iron- and sulfur-oxidizing prokaryotes catalyze sulfide dissolution through the oxidation of ferrous iron and reduced inorganic sulfur compounds, respectively (Fig. 2).
Hace 6 horas · Leprosy, also known as Hansen's disease (HD), is a long-term infection by the bacteria Mycobacterium leprae or Mycobacterium lepromatosis. Infection can lead to damage of the nerves, respiratory tract, skin, and eyes. This nerve damage may result in a lack of ability to feel pain, which can lead to the loss of parts of a person's extremities from repeated injuries or infection through ...

Hace 6 horas · This suggests an adaptation of technologically used yeasts to metabolization of dicarbonyl compounds, possibly as a result of beer yeast domestication. In beer production, 1,2-dicarbonyl compounds such as 3-deoxyglucosone (3-DG) and 3-deoxymaltosone (3-DM) are formed via Maillard reaction or caramelization especially during malt kilning or wort boiling, resulting in substantial concentrations ...

Scientific investigation into the origin of birds began shortly after the 1859 publication of Charles Darwin's On the Origin of Species. In 1860, a fossilized feather was discovered in Germany's Late Jurassic Solnhofen limestone. Christian Erich Hermann von Meyer described this feather as Archaeopteryx ...
Hace 6 horas · Climate change presents significant challenges to agriculture in developing nations, affecting farmers’ livelihoods and food security. In Ethiopia, agriculture is crucial to the economy and the well-being of millions.
