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.
In clayey soil, bacteria are capable of reorienting and moving clay particles under low confining stress (at shallow depths). However, inability to make these rearrangements under high confining stresses limits bacterial activity at larger depths. Furthermore, sediment-cell interaction may cause puncture or tensile failure of the cell membrane.
Microbial metabolism is the means by which a microbe obtains the energy and nutrients (e.g. carbon) it needs to live and reproduce.Microbes use many different types of metabolic strategies and species can often be differentiated from each other based on metabolic characteristics.
Microbial cell factory is an approach to bioengineering which considers microbial cells as a production facility in which the optimization process largely depends on metabolic engineering. [1] MCFs is a derivation of cell factories, which are engineered microbes and plant cells. [ 2 ]
[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 ]
Since the cell wall is required for bacterial survival, but is absent in some eukaryotes, several antibiotics (notably the penicillins and cephalosporins) stop bacterial infections by interfering with cell wall synthesis, while having no effects on human cells which have no cell wall, only a cell membrane.
The mathematical models used to describe the bacterial swimming dynamics can be classified into two categories. The first category is based on a microscopic (i.e. cell-level) view of bacterial swimming through a set of equations where each equation describes the state of a single agent.
While exoelectrogen is the predominant name, other terms have been used: electrochemically active bacteria, anode respiring bacteria, and electricigens. [1] Electrons exocytosed in this fashion are produced following ATP production using an electron transport chain (ETC) during oxidative phosphorylation.
