Xochitecatl is located in a dominant position upon the summit of a 4 km-wide extinct volcano that forms a range of hills that rises approximately 200 meters above the floor of the Puebla-Tlaxcala Valley; the so-called Atlachino-Nativitas-Xochitecatl block, which is located in the centre of the valley.
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.
Bacterial microcompartments are widespread, organelle-like structures that are made of a protein shell that surrounds and encloses various enzymes. provide a further level of organization; they are compartments within bacteria that are surrounded by polyhedral protein shells, rather than by lipid membranes. These "polyhedral organelles ...
Other bacterial cell surface structures range from disorganised slime layers to highly structured capsules. These are made from secreted slimy or sticky polysaccharides or proteins that provide protection for the cells and are in direct contact with the environment. They have other functions, including attachment to solid surfaces.
The root microbiome (also called rhizosphere microbiome) is the dynamic community of microorganisms associated with plant roots. [1] Because they are rich in a variety of carbon compounds, plant roots provide unique environments for a diverse assemblage of soil microorganisms, including bacteria, fungi, and archaea.
Structure of a Type VI secretion system. The type VI secretion system (T6SS) is one of the bacterial secretion systems, membrane protein complexes, used by a wide range of gram-negative bacteria to transport effectors. Effectors are moved from the interior of a bacterial cell, across the membrane into an adjacent target cell.
Food poisoning, also known as foodborne illness, is a common sickness caused by swallowing food or liquids that contain harmful bacteria, viruses or parasites, and sometimes even chemicals.
A detailed and comprehensive literature review on the various aspects of sophorolipids production (e.g. producing micro-organisms, bio-synthetic pathway, effect of medium components and other fermentation conditions and downstream process of sophorolipids is available in the published work of Van Bogaert et al. [5] [16] This work also discusses potential application of sophorolipids (and their ...
