Xochitecatl [ʃot͡ʃiˈtekat͡ɬ] is a pre-Columbian archaeological site located in the Mexican State of Tlaxcala, 18 km southwest of Tlaxcala city. [1] The major architecture dates to the Middle Preclassic Period (1000–400 BC) but occupation continued, with one major interruption, until the Late Classic , when the site was abandoned.
Acetogenesis is a process through which acetyl-CoA [1] or acetic acid is produced by anaerobic bacteria through the reduction of CO 2 via the Wood–Ljungdahl pathway.Other microbial processes that produce acetic acid (like certain types of fermentation or the oxidative breakdown of carbohydrates or ethanol by acetic acid bacteria) are not considered acetogenesis.
It contains a sprawling palace with vibrantly colored murals painted in Maya style. The nearby site of Xochitecatl was a more public ceremonial complex associated with Cacaxtla. Cacaxtla and Xochitecatl prospered 650–900 CE, probably controlling important trade routes through the region with an enclave population of no more than 10,000 people.
Secondary metabolites, also called specialised metabolites, secondary products, or natural products, are organic compounds produced by any lifeform, e.g. bacteria, archaea, fungi, animals, or plants, which are not directly involved in the normal growth, development, or reproduction of the organism.
An acetogen is a microorganism that generates acetate (CH 3 COO −) as an end product of anaerobic respiration or fermentation.However, this term is usually employed in a narrower sense only to those bacteria and archaea that perform anaerobic respiration and carbon fixation simultaneously through the reductive acetyl coenzyme A pathway (also known as the Wood-Ljungdahl pathway).
Primarily produced by Gram-negative bacteria, acylated homoserine lactones (AHLs) are a class of small neutral lipid molecules composed of a homoserine lactone ring with an acyl chain. [7] AHLs produced by different species of Gram-negative bacteria vary in the length and composition of the acyl side chain, which often contains 4 to 18 carbon ...
The Actinomycetota (or Actinobacteria) are a diverse phylum of Gram-positive bacteria with high GC content. [4] They can be terrestrial or aquatic. [5] They are of great importance to land flora because of their contributions to soil systems. In soil they help to decompose the organic matter of dead organisms so the molecules can be taken up ...
While tetanus toxin is produced from Clostridium tetani, a spore forming bacteria found in soil, Tetanus is a paralytic disease that is global and commonly affects newborns as well as non-immunized individuals. Tetanus enters the body of organisms through wounds or skin breaks and can be found in manure, soil, and dust.
