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.
Nitrifying bacteria are chemolithotrophic organisms that include species of genera such as Nitrosomonas, Nitrosococcus, Nitrobacter, Nitrospina, Nitrospira and Nitrococcus. These bacteria get their energy from the oxidation of inorganic nitrogen compounds . [ 1 ]
Xochiquetzal, from the Codex Rios, 16th century.. In Aztec mythology, Xochiquetzal (Classical Nahuatl: Xōchiquetzal [ʃoːt͡ʃiˈket͡saɬ]), also called Ichpochtli Classical Nahuatl: Ichpōchtli [itʃˈpoːtʃtɬi], meaning "maiden"), [7] was a goddess associated with fertility, beauty, and love, serving as a protector of young mothers and a patroness of pregnancy, childbirth, and the ...

The biofilms produced by eukaryotes is usually occupied by bacteria and other eukaryotes alike, however the surface is cultivated and EPS is secreted initially by the eukaryote. [ 92 ] [ 93 ] [ 160 ] Both fungi and microalgae are known to form biofilms in such a way.
[11] [27] These bacteria are important in the primary production of organic carbon because the geothermally-produced H 2 is taken up for this process. [11] Hydrogen-oxidizing and denitrifying bacteria may be abundant in vents where NO 3 −-containing bottom seawater mixes with hydrothermal fluid. [11]
For the Prokaryotes (Bacteria and Archaea) the rank kingdom has not been used till 2024 [115] (although some authors referred to phyla as kingdoms [73]). The category of kingdom was included into the Bacteriological Code in November 2023, [ 116 ] the first four proposals ( Bacillati , Fusobacteriati , Pseudomonadati , Thermotogati ) were ...
[7] [8] Different styles of stromatolite lamination have been described, [9] [10] which can be studied through microscopic and mathematical methods. [10] A stromatolite may grow to a meter or more. [11] [12] Fossilized stromatolites provide important records of some of the most ancient life. As of the Holocene, living forms are rare.
