Lars Ljungdahl
Lars Gerhard Ljungdahl (1926-2023) was a Swedish biochemist, famous for his part in the discovery of the major carbon fixation in the form of the Wood-Ljungdahl pathway as well as lignocellulose degradation by bacteria and fungi. He died in July 2023 at age 96. Education He graduated from Stockholm Stads Tekniska Mellanskola (The City of Stockholm's Technical Secondary School) in 1943. While taking night classes, he received a degree in engineering from Stockholm's Technical Institute (STI) in 1945. In 1958, at age 32, Ljungdahl left Sweden to gain his Master's and then his PhD under Harland Wood at Case Western Reserve University, receiving his PhD in 1964. Research Dr. Ljungdahl focused on anaerobic microorganisms and their interactions with the environment. This led to what can be considered the two main discoveries of his career: the acetyl-CoA pathway, now known as the Wood-Ljungdahl pathway, and the degradation of plant lignocellulose by bacteria and fungi.

Wood–Ljungdahl Pathway
The Wood–Ljungdahl pathway is a set of biochemical reactions used by some bacteria. It is also known as the reductive acetyl-coenzyme A (acetyl-CoA) pathway. This pathway enables these organisms to use hydrogen () as an electron donor, and carbon dioxide () as an electron acceptor and as a building block to generate acetate for biosynthesis. In this pathway carbon dioxide is reduced to carbon monoxide (CO) and formic acid (HCOOH) or directly into a formyl group (R−CH=O), the formyl group is reduced to a methyl group (−CH3) and then combined with the carbon monoxide and coenzyme A to produce acetyl-CoA. Two specific enzymes participate on the carbon monoxide side of the pathway: CO dehydrogenase and acetyl-CoA synthase. The former catalyzes the reduction of the CO2 and the latter combines the resulting CO with a methyl group to give acetyl-CoA. Some anaerobic bacteria use the Wood–Ljungdahl pathway in reverse to break down acetate. For example, sulfate-reducing b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Moorella Thermoacetica
''Moorella thermoacetica'', previously known as ''Clostridium thermoaceticum'', is an acetogenic, thermophilic, strictly anaerobic, endospore-forming, bacterium belonging to the phylum Bacillota. Researchers at the Lawrence Berkeley National Laboratory Lawrence Berkeley National Laboratory (LBNL, Berkeley Lab) is a Federally funded research and development centers, federally funded research and development center in the Berkeley Hills, hills of Berkeley, California, United States. Established i ..., including Peidong Yang, were able to induce ''M. thermoacetica'' to photosynthesize, despite its not being photosynthetic. It also synthesized semiconductor nanoparticles, thus using light to produce chemical products other than those produced in photosynthesis.

Karolinska Institute
The Karolinska Institute (KI; ; sometimes known as the (Royal) Caroline Institute in English) is a research-led medical university in Solna within the Stockholm urban area of Sweden and one of the foremost medical research institutes globally. The Nobel Assembly at the Karolinska Institute awards the Nobel Prize in Physiology or Medicine. The assembly consists of fifty professors from various medical disciplines at the university. The current vice-chancellor of Karolinska Institute is Annika Östman Wernerson, who took office in March 2023. The Karolinska Institute was founded in 1810 on the island of Kungsholmen on the west side of Stockholm; the main campus was relocated decades later to Solna, just outside Stockholm. A second campus was established more recently in Flemingsberg, Huddinge, south of Stockholm. The institute also has a Centre for Reparative Medicine, consisting of two nodes, one in Stockholm and one in Hong Kong. The Karolinska Institute is Sweden's thir ...

Tulane University
The Tulane University of Louisiana (commonly referred to as Tulane University) is a private research university in New Orleans, Louisiana, United States. Founded as the Medical College of Louisiana in 1834 by a cohort of medical doctors, it became a comprehensive public university in the University of Louisiana in 1847. The institution became private under the endowments of Paul Tulane and Josephine Louise Newcomb in 1884 and 1887. The Tulane University School of Law and Tulane University Medical School are, respectively, the 12th oldest law school and 15th oldest medical school in the United States.

Clostridium Ljungdahlii
''Clostridium ljungdahlii'' is an anaerobic, rod-shaped, motile, endospore-forming, gram-positive bacterium. It is named after the Swedish biochemist Lars G. Ljungdahl. When originally harvested from the waste matter of animals, it tended to produce acetate with respect to ethanol, but a major undertaking to increase the ethanol-to-acetate ratio was initiated. A 1993 publication by researchers from the University of Arkansas, in cooperation with Oak Ridge National Laboratories, showed results from a series of continuous reactor studies caused a major change in the bacterium's preference for ethanol production, which increased from <0.1 g/ L to 1.8 g/L in a continuous stirred tank reac ...

1926 Births
In Turkey, the year technically contained only 352 days. As Friday, December 18, 1926 ''(Julian Calendar)'' was followed by Saturday, January 1, 1927 '' (Gregorian Calendar)''. 13 days were dropped to make the switch. Turkey thus became the last country to officially adopt the Gregorian Calendar, which ended the 344-year calendrical switch around the world that took place in October, 1582 by virtue of the Papal Bull made by Pope Gregory XIII.
